Diamond and 1 defense. Diamond and One Defense: Mastering the Junk Defense Strategy in Basketball

What is the Diamond and One defense in basketball. How does the Diamond and One defense work. Why is the Diamond and One defense effective against certain offenses. When should coaches employ the Diamond and One defense. What are the key principles for running a successful Diamond and One defense.

Understanding the Basics of the Diamond and One Defense

The Diamond and One defense is a unique defensive strategy in basketball that combines elements of both man-to-man and zone defenses. It’s classified as a “junk” defense due to its unconventional nature. But what exactly is this defensive setup, and how does it work?

In a Diamond and One defense, four defenders form a diamond-shaped zone, while one defender plays man-to-man defense against the opposing team’s best player. This hybrid approach allows teams to neutralize a star player while maintaining a strong overall defensive structure.

Key Components of the Diamond and One

• Four defenders in a diamond formation
• One defender shadowing the opponent’s top player
• Flexibility to adjust based on offensive positioning

When to Implement the Diamond and One Defense

Coaches often turn to the Diamond and One defense in specific game situations. But when is it most effective to employ this strategy?

The Diamond and One shines when facing a team heavily reliant on a single player for scoring. It’s particularly useful against “one-man teams” or when an opponent has a standout perimeter shooter. By forcing other players to step up, it can disrupt the rhythm of even well-oiled offensive machines.

Ideal Scenarios for the Diamond and One

1. Against teams with a dominant scorer
2. When facing exceptional perimeter shooters
3. To counter predictable offensive sets
4. As a surprise tactic to throw off opponent’s game plan

Setting Up the Diamond and One Formation

The initial setup of the Diamond and One defense can vary depending on the offensive player being targeted. How should teams align themselves to maximize the effectiveness of this defense?

If the shadowed player is a perimeter threat, the defense typically aligns in a 2-3 formation. For post players, a 1-2-2 alignment is often preferred. This flexibility allows the defense to adapt to different offensive threats while maintaining its core principles.

Perimeter Player Focus

When targeting a perimeter player:

• X2 shadows the target player (2) as soon as the ball crosses half-court
• X1 positions at the top of the diamond
• X3 and X4 cover the wings
• X5 protects the paint

Post Player Focus

When targeting a post player:

• X5 fronts the top post player
• X4 positions under the basket
• X2 and X3 cover the elbows to prevent high post passes
• X1 guards the top of the key

Defensive Rotations in the Diamond and One

Effective rotations are crucial for the success of the Diamond and One defense. How should defenders move and adapt as the offense shifts?

When the ball moves, the diamond formation must adjust quickly to maintain defensive pressure. The shadowing defender stays with their assigned player, while the other four rotate based on ball position and offensive movement.

Ball Movement to the Wing

If the ball is passed to the wing (3):

• X5 covers the short corner
• X4 closes out on the ball
• X3 shifts to cover the high post
• X2 continues shadowing their assigned player
• X1 slides to the opposite elbow

Ball Movement to the Shadowed Player

If the ball is passed to the shadowed player (2):

• X5 stays in the middle to protect the paint
• X4 moves to guard the high post
• X3 provides help defense
• X2 closes out on their assigned player
• X1 shifts to the opposite elbow

Keys to Running an Effective Diamond and One Defense

Executing the Diamond and One defense requires more than just proper positioning. What are the essential elements that make this defense truly effective?

Success in the Diamond and One hinges on several key factors:

• Communication: Constant verbal cues help defenders rotate and adjust
• Anticipation: Reading offensive patterns allows for proactive defense
• Conditioning: Covering more ground demands excellent physical fitness
• Discipline: Maintaining proper positioning is crucial for containment
• Adaptability: Quick adjustments to offensive changes are essential

Training Drills for the Diamond and One Defense

Preparing a team to execute the Diamond and One defense effectively requires specific training. What drills can coaches use to reinforce the key concepts of this defensive strategy?

Two essential drills can help players master the Diamond and One:

6 on 5 Half-Court Scrimmage

This drill forces defenders to cover more ground and communicate effectively:

• Set up with 6 offensive players against 5 defenders
• For perimeter focus: Use 4 perimeter players, 1 high post, and 1 low post
• For post focus: Use 3 perimeter players, 1 high post, and 2 low posts
• Rotate players through different positions to build versatility

1 on 1 Shadow Drill

This competitive drill hones individual defensive skills:

• One defender tries to deny the ball to an offensive player for 5 seconds
• If successful, the defender earns 2 points
• If the offense receives the pass, it becomes a 1 on 1 battle (3 dribble limit)
• A defensive stop earns 1 point
• First player to 5 points wins
• Add screeners to increase difficulty and simulate game situations

Advantages and Disadvantages of the Diamond and One Defense

Like any defensive strategy, the Diamond and One has its strengths and weaknesses. What are the pros and cons of implementing this defense?

Advantages

• Effectively neutralizes a team’s best scorer
• Forces less skilled players to make plays
• Disrupts offensive rhythm and set plays
• Provides a surprise element that can catch opponents off-guard
• Allows for easy transition between man-to-man and zone principles

Disadvantages

• Can leave gaps in the defense if rotations are slow
• May struggle against teams with multiple scoring threats
• Requires excellent conditioning and communication
• Can be exploited by patient offenses that move the ball well
• May not prepare players as well for standard defensive schemes

Countering the Diamond and One Defense

Offensive teams facing a Diamond and One defense need strategies to overcome its challenges. How can offenses effectively attack this defensive setup?

Several offensive tactics can help break down the Diamond and One:

• Quick ball movement to exploit gaps in the zone
• Setting multiple screens to free the shadowed player
• Utilizing the shadowed player as a decoy to create opportunities for others
• Attacking the middle of the diamond to collapse the defense
• Employing a 1-3-1 offensive set to stretch the defense

Coaches should prepare their teams to recognize and exploit the weaknesses inherent in the Diamond and One defense. This often involves emphasizing ball movement, player movement without the ball, and capitalizing on mismatches created by the defensive alignment.

Advanced Variations of the Diamond and One Defense

Experienced coaches often develop variations of the Diamond and One to suit their team’s strengths or counter specific offensive threats. What are some advanced adaptations of this defensive strategy?

Rotating Diamond

In this variation, defenders in the diamond formation constantly rotate, making it harder for the offense to find gaps:

• Defenders move in a clockwise or counterclockwise pattern
• Rotations are timed with offensive ball movement
• Requires excellent conditioning and communication

Double-Shadow Diamond

This aggressive variation assigns two defenders to shadow key offensive players:

• Three defenders form a triangle zone
• Two defenders play man-to-man on the top offensive threats
• Highly effective against teams with two dominant scorers

Flex Diamond

The Flex Diamond allows for seamless transitions between different defensive looks:

• Defenders can quickly shift between Diamond and One, Box and One, or standard zone
• Keeps the offense guessing and disrupts rhythm
• Requires versatile, intelligent defenders

Implementing the Diamond and One in Different Game Situations

The Diamond and One defense can be particularly effective in certain game situations. When and how should coaches consider employing this strategy for maximum impact?

End-of-Quarter Scenarios

Using the Diamond and One in the final minutes of a quarter can disrupt the opponent’s set plays:

• Prevents easy looks for the top scorer
• Forces less experienced players to make decisions under pressure
• Can lead to turnovers or poor shot selection

Protecting a Lead

When holding a lead late in the game, the Diamond and One can be an effective way to maintain control:

• Slows down the opposing offense
• Limits opportunities for quick scores
• Forces the offense to use more time to find good shots

Coming Back from a Deficit

Implementing the Diamond and One when trailing can help spark a comeback:

• Disrupts the opponent’s offensive rhythm
• Can lead to turnovers and fast-break opportunities
• Psychologically shifts momentum by introducing a new challenge

The Psychology Behind the Diamond and One Defense

Beyond its tactical advantages, the Diamond and One defense can have significant psychological impacts on both teams. How does this defensive strategy affect player mentality and team dynamics?

Impact on the Offensive Team

The Diamond and One can create several psychological challenges for the offense:

• Frustration for the shadowed player who may feel limited
• Pressure on secondary players to step up offensively
• Confusion and hesitation when faced with an unfamiliar defense
• Potential for team discord if the offense becomes stagnant

Benefits for the Defensive Team

Implementing the Diamond and One can boost the defending team’s morale and focus:

• Increased engagement due to the unique defensive assignment
• Sense of empowerment in neutralizing the opponent’s top threat
• Enhanced team cohesion through necessary communication and cooperation
• Psychological edge gained from disrupting the opponent’s game plan

Understanding these psychological factors can help coaches prepare their teams mentally, whether they’re implementing or facing the Diamond and One defense. It’s not just about X’s and O’s; it’s about managing the mental game as well.

The Diamond and One “Junk” Defense

The Diamond and One is the perfect changeup to either a man-to-man or zone defense. It serves three purposes: to contain the opposing team’s best player, to take away the strengths of that player, and to disrupt the opponent’s rhythm on offense.

This defense is designed to shut down the other team’s best player by cutting off open looks. It is the perfect defense against a “one man” team since it forces other players to beat you. The opposing offense will probably line up in a 1/3/1 set to combat either defense. They will often attack it as if playing against a zone.

Starting out, the Diamond and One aligns into a 1-2-2 or a 2-3 defense depending on the offensive player being shadowed. If the player being shadowed is a perimeter player, line up in a 2-3. If the player being shadowed is a post player, line up in a 1-2-2. This wrinkle will disrupt the rhythm of the opposing offense.

Note: Breakthrough Basketball recommends youth teams playing man-to-man defense.

If the top perimeter player is 2, X2 shadows 2 as soon as the ball crosses half-court. X1 lines up in the top of the diamond.

If the top perimeter player is 1, X1 guards the ball. X2 lines up in the top of the diamond.

If the ball is passed to 3, X5 covers the short corner. X4 closes out on the ball. X3 covers the high post. X2 still shadows 2. X1 slides to the right elbow.

If the ball is passed to 2, X5 stays in the middle. X4 moves to the middle to guard the high post. X3 plays help defense on 2. X2 closes out on 2. X1 slides to the left elbow.

If the top opposing player is a post player, the defense should initially align in a 1-2-2. Switch to the Diamond and One as soon as the ball crosses half-court.

X5 fronts the top post player. X4 is under the basket. X2 and X3 are on the elbows to cut off any initial pass to the high post.

If the ball is passed to 3, X5 fronts 5. X4 is under the basket. X3 closes out on the ball. X2 denies the pass to 4. X1 slides to the right elbow.

If the ball is passed to 2, X4 switches onto 5. X5 is under the basket. X3 slides to the middle. X2 closes out on the ball. X1 slides to the left elbow.

Here are two simple drills to reinforce three concepts crucial in running the Diamond and One: denying the ball, covering ground on the zone, and fighting through screens.

Drill #1: 6 on 5 Half-Court Scrimmage

Guarding an extra player in practice will bode well for the Diamond and One during the game. It will force your players to cover more ground.

If your team is game planning against a top perimeter player, the offense should use four perimeter players, a high post, and a low post.

If your team is game planning against a top post player, the offense should use 3 perimeter players, a high post, and two low posts.

Drill #2: 1 on 1 Shadow Drill

The 1 on 1 Shadow Drill is a fun and competitive way to develop your players’ ability to shadow the offensive player on the perimeter.

The goal for each player is to earn 5 points to win the competition. Each player gets 2 points for successfully denying the ball and 1 point for getting a defensive stop.

The defender’s goal is to deny the ball for more than five seconds. Denying the ball for a five second count is worth 2 points.

If the pass is made, it becomes a 1 on 1 battle. The offensive player is limited to three dribbles.

If the offense scores, the offense switches to defense. The defense switches to the middle.

If the defense gets a stop, the defense stays on defense. The offense switches to the middle. The middle switches to offense.

Add screeners to make it more challenging for the defender to deny the ball. Teams usually set screens to get their best players open. It is crucial to teach your players how to fight through screens.

Same rules apply as before. If 2 catches a pass, 4 and 5 can set ball-screens but are not allowed to score. 2 is also not allowed to pass to 4 or 5.

Diamond And 1 Defense – Hoop Student

The diamond and 1 defense is a type of junk defense in which one defender plays man to man defense while the other defenders set up in a diamond-like zone defense.

The diamond and 1 defense is a variation of the box and 1 defense and can be considered against teams with good outside shooters.

In addition, the low post zone defender should be agile enough to move from block to block and have above average low post defense skills.

The main objectives of the diamond and 1 defense is to use the defensive team’s best defender to limit and/or eliminate scoring/play-making opportunities for the offensive team’s best player.

The best defender is typically known as the chaser while the best offensive player can be called the target.

The chaser limits opportunities for the target by implementing certain the man to man defensive techniques known as deny defense and pressure defense.

If the target does not have the ball, then the chaser will face guard and deny from baseline to baseline.

The ball denial action of the chaser causes the target to work that much harder to get open and receive the ball.

On the other hand, if the target is able to receive the ball, then the chaser applies on-ball pressure defense.

Good on-ball pressure can make it much more difficult for the target to score or make plays for the other teammates.

Also, as a side effect of the ball denial and/or defensive pressure, the target will have to use more energy than normal.

If that occurs, it can potentially affect that player’s ability to perform at an optimal level towards the end of the game.

In addition, if middle penetration happens from the top or wing areas, then one or more of the zone defenders can help and recover similar to the pack line defense.

The section below goes over the general principles, defensive rotations, and drills of the diamond and 1 defense.

General Principles

This section contains a few general principles of the diamond and 1 defense.

Deny defense
The chaser that is playing man to man defense should always try to deny the entry pass to the target whenever possible.

Pressure defense
If the target is able to receive the pass, then the chaser should apply maximum pressure defense.

However, it is also important for the chaser to not reach in to steal the ball carelessly.

If that occurs, the chaser can potentially get in foul trouble which would be bad for the defense.

High post defenders cover wings and corners
In the box and 1 defense, the high post defenders typically only cover the wing and periodically step out to guard the ball handler at the top of the key.

Also, the low post defenders cover the low post and corner areas.

However, in the diamond and 1 defense, the high post defenders are required to cover both the wings and the corners.

Therefore, the high post defenders have to be fast enough to closeout to a wing or corner when the ball is located in those court spots.

Defensive rebounding
The box and 1 defense features at least two low post defenders.

However, the diamond and 1 only has one primary low post defender near the basket.

Therefore, it is very important that all four zone defenders box out offensive players that are nearby on every shot attempt.

Chaser should be best defender
When considering the diamond and 1 defense, the chaser should be the team’s best defender but not necessarily the team’s best scorer.

If the chaser is the team’s best scorer, then that same player will most likely tire out more quickly on the offensive side of the ball.

Also, if the best defender just happens to be the best scorer, then the coaching staff should consider making the second best defender as the chaser.

Chaser is usually a guard
Generally speaking, the point guard and/or shooting guard player positions are usually designated as the chaser.

However, the chaser could also be a small forward or perhaps, even a power forward if those defenders are mobile enough to move on the perimeter consistently.

This could also be beneficial to the defense because those players usually have longer arms which makes it much easier to contest potential jump shots taken by the target.

Chaser always goes over the top
The chaser should always follow the target over the top (or the high side) whenever the target moves from baseline to baseline.

The chaser should not follow behind the target (or the low side) while in pursuit mode.

The main goal of the chaser is to always deny the entry pass first and then play 1 on 1 pressure defense if absolutely necessary.

Chasers can be switched
If the team has two or more really good defenders, the coaching staff can decide to switch out chasers periodically.

This type of defensive tactic would more than likely frustrate the target as that player will have to adapt to a brand new defender in an effort to get open.

Ball at top
When the ball is at the top of the key, the top defender takes a step above the three point line to apply pressure defense to the ball handler.

The high post defenders start at the extended high post and match up with corresponding offensive players located on the wings.

In addition, high post defenders collapse and cover the high post if the ball is located there.

The low post defender stays in the center of the lane to protect the basket.

The chaser guards the target and denies the wing or corner pass.

Ball on wing
If the ball is passed to a wing, then the high post defender on that side will guard the ball handler.

Also, the low post defender cuts across to guard the low post defender located on that side of the floor.

The defender that was located at the top drops back to protect the nail and to help and recover on possible middle penetration.

The weak side high post defender also drops back to provide weak side help defense for the low post and to prevent easy basket cuts from that side of the floor.

Ball in corner
If the ball is in the corner, then the high post defender on that side would have to sprint and closeout on the offensive player located in the corner.

The defender that was initially at the top will slide over to the extended high post on that side to provide help defense if middle penetration occurs by the corner player.

The strong side low post defender continues to front the strong side low post while the weak side high post defender continues to drop back and provide help defense if necessary.

Ball in the high post
If the ball is in the high post, then the high post defenders can execute the double team to try to force the ball out of the high post.

The downside to this is that the perimeter shooters are left open on the wings, at least temporarily.

The low post defender continues to protect the basket while the chaser continues to face guard and deny the target.

Top

For this example, X1 steps out to apply defensive pressure to the 1-man.

X3 and X4 match up to guard the 3 and 4 respectively while X5 covers the basket.

The chaser X2 face guards and denies any potential pass to the 2-man who is the target.

If the 2-man moves from one side to the other, X2 chases behind on the high side while still executing deny defense.

Wing

For this example, 1 has made a pass to 3 while 2 has cut through to the left side corner.

Next, X4 steps out to apply defensive pressure to the 4-man.

X1 drops back to protect the nail and to use the help and recover defensive technique on potential dribble drive action by 3.

At the same time, X5 slides across towards the left low post block to guard the 5-man preferably with a three-quarter low-side front.

In addition, in this instance, X3 also drops back to provide potential help defense if the ball gets into the post.

Also, if the 3-man that is located on the weak side perimeter were to cut to the basket, X3 is available to prevent easy scoring opportunities on that side of the floor.

X2 chases behind the 2-man on the high side and continues to execute man to man denial defense.

Corner

For this example, let’s assume the 3-man was located in the corner and received a pass from the 4-man.

If that were to happen, then X4 would have to sprint to closeout on 3 to prevent an easy, uncontested jump shot.

At the same time, X1 slides over from the nail spot to the extended high post to provide help defense on a potential middle drive if necessary.

X5 continues to front while X3 provides help defense if the ball gets into the low post.

X2 continues to face guard the target which is the 2-man.

High Post

This is probably the main weakness of the diamond and 1 defense.

If the ball gets into the high post, then at least one of the perimeter defenders will have to leave their defensive assignment open for at least a second or longer.

If the ball is passed back out to the perimeter, then that corresponding defender would have to quickly closeout to prevent an open jump shot.

In this example, the 5-man receives the ball in the high post.

When that occurs, X1 and X4 can execute a double team in an attempt to get the ball out of the high post.

X3 could also execute the double team with X1 but for the example X4 was chosen.

X3 stays near the extended high post to guard 3 while X5 continues to protect the basket.

Also, X2 the chaser continues to deny the ball for the 2-man.

Covering the Target

For this example, the target was able to receive the pass on the right side wing from the 1-man.

When that occurs, the chaser X2 applies defensive pressure to prevent the 2-man from getting easy, open jump shots.

Also, the other four diamond zone defenders move back into the initial alignment near the low and extended high posts.

If the 2-man drives middle, then X3 is ready to help.

On the flip side, if 2 drives baseline, X5 can help on the strong side while X4 drops back into the lane to execute the help the helper principle.

Drills

This section contains defensive drills for the diamond and 1 defense.

Chaser

In this drill, 1, 2, and 3 are the targets while X1, X2, and X3 are the chasers.

The coach is the passer indicated by the letter C at the top of the key.

The first target and chaser combination is 1 and X1 respectively.

1 takes the screens set by 4 and 5 going from baseline to baseline in an attempt to get open.

X1 cuts across the high side of 1 in an attempt to deny and/or deflect/steal the pass from the coach.

Once 1 receives the ball and takes a shot attempt or X1 gets a deflection/steal, an offensive or defensive point is given.

After that, the next target/chaser combination which is 2 and X2 participates in the drill.

5 on 4 Shell – Ball At Top

For this example, the 1-man has the ball at the top of the key.

X1 applies defensive pressure to the ball until it is passed to another location.

X2 and X3 guard the wing areas while X4 protects the basket.

5 on 4 Shell – Ball On Wing

1 makes a quick pass to the 2-man on the wing.

After that, X2 makes a quick closeout on the 2-man.

At the same time, X4 executes a three-quarter front on the high side to prevent an easy post entry pass into the 5-man.

Also, X3 drops back into the lane from the weak side high post to provide help defense and to protect against a potential lob pass over the top of X4.

X1 also drops back from the top of the key to protect the nail spot near the free throw line.

5 on 4 Shell – Ball In Corner

For this example, 3 has cut through to the right side corner and receives a pass from the 2-man.

Once the ball is in the corner, X2 makes a quick closeout on the 2-man.

Also, X1 slides over again to temporarily cover the 2-man.

If the ball is reversed back to the 2-man, then 1 can quickly contest a potential jump shot if necessary.

Additionally, since this is a 5 on 4 drill, at least one offensive player would always be open.

However, in the actual diamond and 1 defense, the open player would actually be covered with man to man defense.

Therefore, in this case, with the ball in the corner, the 1-man is left open on purpose.

Box & One Combination Defense

| Diamond Shifts | vs Odd Front | Post Double Team | Chaser |

A derivative of the Box & One combination defense is the “Diamond & One.” Similar to the Box & One, four defenders play zone while the fifth player assumes a strong pass denial position against the opponents scoring ace. The Diamond & One is best deployed when the opponents use an odd or one guard front offense.

CAUTION: Although the diamond and one is very effective in taking away the middle, it does give up the corner. If/when the corner does becomes a problem, switch to a Box & One alignment.

Shifts by Position

In the diamond and one, post X5 stays inside maintaining a low position between the ball
and basket. Wings X3 and X4 must cover the area from the free throw line extended to the corner. They do this by assuming a mid position having
one hand up when the ball is on the wing and the other hand up when the ball is in the corner. Point X1 defends the high post area, elbow to elbow.

vs.

an Odd Front Offense

Low Post Double Team

The Diamond and One combination defense lends itself readily to double teaming a strong post player.

Defensive Chaser

The key element to the Box & One defense is the ability of the chaser(s) to deny their assigned opponent the ball. This strong denial will not only keep the ball out of the hands of the opponent’s star scorer, but will also completely disrupt and break down the opponent’s set plays and continuities.

Defence – Diamond and 1

Box and 1 Defense Guide

The first decision you need to make when it comes to the Box and 1 is which one of your players is going to be the Chaser. Depending on who the star player is will also dictate who is the Chaser, but you do want to make sure the Chaser will be able to keep up with the star player.

The second decision is assigning the other four players to the box defender positions. Generally, your two tallest players will be your Low Box Defenders and your two shortest players will be the High Box Defenders.

Now lets breakdown the Box Defenders rotations because we know what the Chaser should be doing at all times – denying the ball to the star player.

Star Player Has The Ball

When the star player does manage to get the ball (and they will), all box defenders immediately collapse into the original box formation depending on where the ball is on the floor.

With the box formation, you have great help defense if the star player decides to attack with their dribble. As the box defenders help it will leave open players on the perimeter but with this defense that is a good thing. We want the star player to give up the ball and pass out to open teammates on the perimeter!

Basketball at the Top of the Key

When the ball is at the top of the key there will not be a specific player guarding the ball. The two High Box Defenders will be near the high post to discourage a pass to the middle of the zone. We want the offense to pass the basketball around the perimeter.

The two Low Box Defenders will each have a foot in the lane and the Chaser will be in complete denial.

Basketball on the Wing

When the ball is passed to a wing player, the ball-side High Box Defender will close out and guard the ball. The weak-side High Box Defender will slide across to the middle of the lane and deny the high post area.

The ball-side Low Box Defender must be fronting in the low post and the weak-side Low Box Defender should slide across to be in the middle of the lane. This will help prevent any lobs passes being thrown over the top. The ball-side Low Box Defender has to be fronting in the low post because when the ball goes to the corner they have to be able to close out and contest the shot.

The Chaser is in complete denial.

Basketball in the Corner

When the ball is in the corner it’s the ball-side Low Box Defenders responsibility to close out and guard the ball. You don’t want the offense to drive baseline from the corner so make sure you close out forcing the offense back to the middle

The weak-side Low Box Defender now slides across completely and guards the low block. If there’s no offense on the block then they stay in the middle of the lane in help position.

The weak-side High Box Defender drops into the gap to prevent any passes to the middle of the lane.

The ball-side High Box Defender has options for how to defender when the ball is in the corner.

1. 1. 1. 1. 1. Drop Back – this prevents any pass inside but does allow a pass back out to the wing.
            2. Hard Deny – this prevents any pass back out to the wing and forces the offensive player to make a tough pass which could possibly lead to a turnover
            3. Trap the Corner – this isn’t an option to do all the time, but it would catch the offense off guard

The Chaser is in complete denial.

Basketball in the High Post

When the ball gets to the high post, it’s a pick your poison scenario. You can have your High Box Defenders collapse onto the ball and double team while the Low Box Defenders hold their ground so there isn’t an easy dump pass.

With the double team, it will pressure the high post to make a decision. If your Low Box Defenders stick to their ground down low then there won’t be any passes in the lane and the high post will have to pass out to the perimeter.

If that happens, the High Box Defenders will have to recover quickly.

The Chase is still in complete denial.

Basketball in the Low Post

The Low Box Defenders have to do everything they can to make sure an offensive post player doesn’t get a seal on them in the low post. Your defenders should always be fronting or working to get post players out of their position.

If the offense gets a seal on the ball-side defender, play it straight up because it’s another pick your poison scenario. If the offense takes advantage of the three-point shot in the corner then the ball-side High Box Defender could sprint to challenge it.

The 1-2-1-1 Diamond Press Defense

Most of you who watch Clemson basketball are familiar with our pressure defense, but you may not understand how its implemented. This post is the first in a series that is meant to help expand our understanding of what exactly Clemson is doing out there, and to help you see what they do right and what they do wrong. Its not going to help those who already know a lot about basketball, just a few primers on the offense and defense we run the most often for those that don’t. Oliver Purnell’s favorite zone pressure is the Diamond, or 1-2-1-1.

What is it?

The full court Diamond-and-one defense gets its name from the alignment as seen from above the court. One player stands under the basket, with two players at the corners and another at centercourt to make a diamond shape. The 5th player is the last line of defense in the lane if the press is broken. The difference between the Diamond and the 1-3-1 is really just the position of the guy trying to make the steal. Notice in the pic below on the left, the 4 is under the post, depending on the coach’s philosophy about attacking the inbound or your personnel, and if 4 is a good interceptor of passes or the opponent is a good passing team, you can switch the PG and the 4 in initial alignment. This is a gameplan adjustment for an opponent, but I’ve seen Clemson play both depicted below (generally the one on the top, but we’ll explain the 2nd).

The Press has two primary goals, which you’ll be able to tell from how it aligns:

• Force the ball to their handler along the sideline, where he can be “trapped” by two guys and forced to lob the ball over their heads where it can be intercepted. In this case the front defender will stand at center court and try to assure the pass to the other corner.
• Force the ball to a particular handler or even deny the inbound pass. In this case the frontline defender can jump in front of the inbound man and try to intercept the pass, or set himself up so that he forces the pass to be made to the short side of the court.

So the first thing to point out is that its not the front defender’s job to stop the ball, he’s there only to try to make them pass it to one of the guys on the wing, so that then the ballhandler can be double-teamed or that pass intercepted. He should always be even with the ball.

After the pass is initiated, two defenders are supposed to run to it, with arms UP, and try to pin him against the sideline. This will be the X2 or the X3 along with another defender depending on where the pass was made (X denotes a defender, P an offensive player). The X2/3 stays back just far enough so that the inbound pass can’t be thrown behind him. If their Guard pulls back and tries to dribble around, the point defender should be there to force him to head back into the trap. One of the 2 men on the corners will come up to keep him from coming down the court. Remember, time is on the side of the defense. 

For example, if I was running a half court diamond, and if there was a P1 on X1 matchup, and he takes the ball to the left wing, our X2 should come up in front of him and keep him from coming down the court. If he goes right, the X3 should come up and prevent.

When you see the opposing Guard double-teamed, you should watch the arms of the defenders, they should be up and out away from their bodies, not reaching in to take the ball away, unless he dribbles face-on with them. If they keep their hands down and try to reach to take the ball away, they’ll get a foul called. This is not a smart foul while in the backcourt.  The defender should only move his feet into the correct position to trap the ballhandler. Their goal is only to force a bad pass by making him pick up the dribble, or get a 5/10 sec call and get the turnover. Someone else is supposed to rotate up from the other side to midcourt and pick off the pass, which should be the other corner/wing defender.

The gap-man at midcourt (who may be an X1 or X4, depending) is to shift over and stop any high arcing pass to the opposite sideline, while the 5 (the safety) stays in the lane in case the press is broken. If you see a pass and an easy layup, its because X5 was out of position to stop it, or he was outnumbered and didnt want to foul. He’ll only come out to trap someone when the ball gets to the defensive corners down the court. X1/4 will only trap at the midcourt area with one of the two wings, the X2 or the X3. In a full court set, he parallels the movement of the ball: if its passed to one side of the court (side to side, not the length) then he is supposed to shift to that side. The other wing shifts back into the middle to stop any pass to the side where he was just standing. The X5 will shift but its not but a few feet, he stays in the lane or atop the key.

For example, the inbound pass is forced to P1 on one side of the court. Lets say the X2 comes up to guard, while the X1 runs over to trap P1. The offense brings up another guard P2 to the other side of the court, giving them 3 men in the area: P1, P2, and the inbounder P3. See below.

The ball is reversed back to the inbounder P3. The X1 then hustles over to help the X3 who comes up to trap, while the X2 backs up and prevents a pass back to the original ballhandler. The X4 moves closer to the sideline at midcourt, and X5 steps over to that ballside of the lane.

If the ball gets to the mid court line, the X4 should be there to prevent them from coming down the sideline, with a wing defender to assist him in trapping. The X4 moves into the backcourt area, and watches for them to pass the ball across him, keeping in mind that they cant cross that mid court line again.

So you see they are just supposed to shift left and right, keeping the diamond alignment, as the ball travels down the court.

If the ball makes it past this trap, there could be an offensive player standing in the corner down that sideline. Imagine the P3 coming down to the corner in the picture above. You’ll see the X5 come over to guard him and prevent a 3 point shot from the corner. Whomever was helping the trap will now come down and help 5, while 4 rotates back into the post area. The X2 should already be watching from the lane to prevent a pass to the backside, while the PG should be at the top of the key.

All the way down the court, there should be a 1-2-1-1 alignment. If they can get the ball past the press like this, the defense will usually settle into a half court man/man or a zone. Sometimes you’ll notice us give up the trap after the first attempt fails to get a turnover, called a “one and done” trap.

Thats the basics of a 1-2-1-1, but both Clemson and Tennessee do run it slightly differently, with the X4 standing under the post guarding the inbounder. He’s not really guarding him, but stands there with his arms flailing and forces the pass to the short side. The PG will be back in the middle. The X4 will then go over to the wingman and help trap the man who receives the inbounds pass, or will back up to midcourt while the X1 will come up to trap.  I can recall Clemson doing both, but the man at midcourt needs to be able to move and intercept passes. Obviously this will be changed around considering who is actually in the game, because if the P3 (in the diagram) who receives the inbounds can just run by the defenders, the whole press is shot. Below is a very aggressive press where the X5 is up the court.

The X3 will be anticipating the pass back to the inbounder, while our X1 will stand between the two offensive players near midcourt and try to intercept any pass to either of them. His job is to read the shoulders of the passer: if parallel to the baseline, look to the P3 to the sideline on his left; if parallel to the sideline, look to his right to the P2.

How do most teams attack the Diamond in the full court?

You might see something like a 1-2-2 alignment initially, but there are alot of ways to attack it with various screens but the general weakness of the diamond is up the sidelines. If a team consistently beats you up the sideline, you have to adjust to something like a 1-2-2 press (X5 will come up opposite X2 into the backcourt). Clemson also runs a 1-2-2 pressure at times. There will be the inbounder and 2 guards on the corners, who will start running, and their job is to take the ball quickly and pass it down court before they can get trapped to one of the other two men down the court. Once they’ve passed it down the court they’ll have a potential numbers mismatch against the lane defender X5 and the defense must quickly get back into their half court set.

And thats why you see pure athletes playing ball at Clemson who may lack a particular skill offensively. You are forced to recruit smaller lineups, so you have to fight to win on the boards. If they are not quick, they wont be able to come up to trap before the Guard reacts, and also won’t be able to get down the court if the press is beaten with a good pass. Big guys don’t always run so fast. You need guys that can run full speed, stop and shoot a 3 pointer or jumper on offense.  Thats hard to do and keep it going.

If an offense has a really strong guard, you will not see as much challenging of the inbound passer, the defense will set up to take out their best guard by double-teaming him on the inbound pass, forcing the inbounder to push the ball to a weaker ballhandler. Once its in, the PG runs over to trap, and the man thats left on their best guard tries to prevent a pass back to him.

Comprehensive information protection in ground-to-board channels | Vatrukhin

Introduction

In the article “New possibilities of using short-wave radio communications in solving aerospace defense tasks by combat aviation”, published in No. 2 of 2017 of this journal, the issues of new information capabilities of combat aircraft outside the radio horizon based on adaptive short-wave radio communication technologies were considered, implementing the quality of radio traffic comparable to line-of-sight.

This material is a continuation of the topic in terms of one of the key aspects of the quality of radio traffic, which was practically not touched upon in the previous article – the possibility of providing comprehensive protection of information from all possible influences on it during transmission in channels with unpredictable characteristics, primarily short-wave. The topic of the article refers to the issues of maintaining the integrity and secrecy of information in conditions of interference and radio resistance by the domestic innovative technology of complex information protection against interference, imitation and unauthorized acquaintance, implemented by stochastic codes with one-time redundancy .

The possibility of widespread use of this technology is the result of many years of research by domestic scientists in the theory of data transmission and information protection, Ph.D. L.M. Finka, Doctor of Technical Sciences IN AND. Korzhika, Ph.D. S.A. Osmolovsky, Doctor of Technical Sciences G.A. Kabatiansky, Doctor of Technical Sciences I.Yu. Zhukova, Doctor of Technical Sciences M.A. Ivanova and others [1–49]. S.A. Osmolovskiy (1946–2018), a student of one of the theoreticians of the theory of communication, Doctor of Technical Sciences. L.M. Finca.

With this article, the author would like to pay tribute to the many years of work of a comrade and classmate.

The main factor of information distortion has always been and remains the constant presence of interference in communication channels, especially in radio channels. The fight against them is traditionally carried out by using error-detecting and / or error-correcting codes, which are implemented, as a rule, in data transmission equipment (ADF). The most widespread in aerial communication networks of videoconferencing was received by the APD type R-098 (“Pass”), which has been in operation over the past several decades.

Radio countermeasures are capable of fully or partially suppressing information exchange and / or changing and imposing false information. Protection against such influences is provided by special codes of imitation protection, implemented in individual devices. It is possible to neutralize the suppression of the exchange of concentrated noise interference by means of software tuning of the operating frequency (PFC), changing the direction and width of the antenna radiation patterns, etc.

Confidentiality of information, that is, protection from unauthorized acquaintance, is usually ensured by special encryption equipment using cryptographic codes. In some cases, this equipment solves the problem of confidentiality and imitation protection at the same time.

All the mentioned protection functions are traditionally solved independently of each other by similar code constructions in various types of equipment, but they have one ultimate goal – preserving the integrity of information. At the same time, violation of confidentiality can also be considered, in a sense, as a violation of its integrity, inviolability for outsiders.

All security functions are provided with codes that have some quantitative redundancy, due to which arrays of so-called “prohibited” code combinations are formed, into which, under the influence of interference, information-carrying “permitted” combinations can be transferred. Cryptographic codes of secrecy are formed somewhat well, where the main distinguishing factor of their design is a statistically equiprobable sequence of signals transmitted to the channel and not depending on the statistics of the appearance of individual letters in the original encrypted sequence.

Intuitive understanding of the influence of redundant coding on the fidelity of the received discrete data as a tool to increase the reliability can give an analogy with the process of a confidential conversation between two subscribers over a telephone channel with a lot of noise. In this process of “data exchange” illegible words and even individual letters have to be repeated several times at the request of the recipient. The more refinements and repetitions in the end, i.e. the longer the “code structure – information block”, the closer the adopted phrase is to the original, i.e.That is, the reliability of the information is higher.

It can be assumed that if the subscriber is able to receive at least something meaningfully in noisy conditions, then it is possible in the end to achieve reception with 100% reliability of any complexity of the phrase, even in the most difficult interference conditions.

A similar meaning of this phrase for a discrete channel is contained in one of the main theorems of information by K. Shannon, which claims that, in principle, you can get an arbitrarily high reliability of the received information if the speed of its transmission in the channel is less than its bandwidth (i.e.That is, the worst state of audibility – “throughput” in the above example, in which there is still an opportunity to meaningfully accept words and after changing which downward communication becomes useless due to the complete cessation of understanding the meaning of what is spoken).

Continuing the analogy with a telephone conversation, let us also assume that someone in the next room wants to record an overheard conversation with the help of technical means. The subscriber has this possibility in mind and to prevent unauthorized recording includes tap water, “stochastic”, i.e.That is, random, the noise of which makes it impossible to retain the meaning of the conversation while recording. This comparison is similar to the influence of random signals on data secrecy when further considered in the article the concept of a q-ary symmetric channel.

The most important parameter for evaluating the efficiency of data exchange is the reliability of the information received, which depends mainly on the probability of an error that is not detected by a specific security code (p _but ). An undetected error is, in fact, a loss of information arising from the transformation, under the influence of interference, of a “permitted” combination back into a “permitted” one, but corresponding to another symbol. Therefore, to reduce this transition probability, it is desirable to choose a code with a large percentage of forbidden code combinations, which is possible only with an increase in the number of redundant symbols, and therefore by increasing the length of the code combination .

Of the existing set of redundant codes that detect and correct errors, only a very small part of them is used in practice: Hamming, BCH, Reed – Solomon codes, convolutional and recently appeared turbo codes [26].This is explained primarily by the fact that the distribution of errors in real communication channels is such that none of this set of codes can provide a predetermined or guaranteed (in the interest of increasing the accuracy of the implementation of a specific information process) the probability of correct reception of information in a specific communication channel …

All of them were created with an orientation to some mathematical models of channels, which only in very rough outline describe the properties of real communication channels [5] [8].

The most often used in calculating the parameters of the noise protection code is a model of a certain idealized channel, called the “binary symmetric channel” (BSC), where the errors have equal distortion probabilities “0” or “1”.

The most striking example of non-stationary channels is short-wave. The instability of their characteristics, as well as the presence of constant grouping interference, has not allowed to create their mathematical model of acceptable accuracy to this day.

A search has begun for such a model, preferably a universal one, for which it would be possible to create a code that, for given values ​​of n and k (where n is the length of the codeword with redundancy in bits, k is the length of information bits in the codeword), provides in any communication channels some guaranteed value p _but .At the same time, it is desirable that at small p _but (about 10 ^–9 –10 ^–8 ), the consumer would practically not be given false information, and a decrease in the transmission rate (n / k) of information should be a signal for switching to another the quality of the communication channel.

A method for creating such a code was developed by a team of specialists from the Military Academy of Communications in the 70s of the last century, headed by D.Sc. L.M. Fink [1].

In the article “Universal stochastic coding in systems with decision feedback” was mathematically substantiated method of obtaining a given probability of undetected error by the method of random coding using stochastic transformations .

Random coding introduced by K. Shannon for error-correcting coding is understood as a random selection of code words from a set of possible combinations with a length equal to the length of the code.

The formula (1) obtained in this work for the probability of an undetected error in any channel is so simple that it becomes obvious that it is necessary to construct very long codes with high redundancy to obtain a small p _but

p _but <1/2 ^n-k .(1)

The creation of a new universal code was inextricably linked with the practical implementation of a new channel model, the so-called q (ku) -ary symmetric channel, without which the new code did not make sense to use, since these are, in fact, two sides of the same coin. With the new model, it became necessary to revise some of the traditional views on the rules for constructing, encoding and decoding error-correcting codes.

The concept of a q-ary symmetric channel, strictly speaking, already existed, but only as a mathematical abstraction.The merit of S.A. Osmolovsky is to transform an abstraction into a real model and create for it noise-immune random redundant codes, hereinafter called stochastic codes, which have a number of original properties in a q-ary symmetric channel. The author came to the conclusion that it makes no sense to use any of the classical codes within the framework of the new model due to the loss of their properties associated with detection, localization and correction of errors: it is necessary to create a new code using the fact of the presence of a transformed discrete channel.In the scheme he implemented (Fig. 1), the double sequential transformation proposed in [1] is applied: encoding operations (encoder K) and direct stochastic transformation using a pseudo-random sequence on the transmitting side (R) and operations of inverse stochastic transformations and decoding on the receiving side. A set of two stochastic converters R and R ^–1 , connected by a discrete communication channel DC, forms a q-ary symmetric channel.

Fig.1 . Scheme of data transmission in a q-ary symmetric channel using stochastic coding

A binary message is split into L-bit binary sets – q-ary symbols, the total number of such symbols is q = 2 ^L , an nL-bit code sequence is considered as an n-bit code block consisting of q-ary symbols, of which k – informational, and n – k – redundant.

In the K coding block, the information AND is converted into a binary n, k code with further formation into code blocks of length n q-ary symbols, where k symbols are information symbols.Then the information enters the block of the direct stochastic transformation R, which implements the randomization function (Random) of the data in a binary discrete channel (DC) on random tables with double stochastic transition matrices, the block of the inverse stochastic transform, which implements the function R ¹ , the decoding block, in which errors are detected and corrected and the consumer is issued I ¹ [2]. The randomization of binary sequences also serves as a means of improving the accuracy of describing decoding outcomes.Blocks R and R ¹ convert each q-ary symbol, and the conversion result is statistically independent of the conversion results of other symbols of the code sequence, which is inherent in cryptographic algorithms.

The property now possessed by the converted channel is the equiprobability of all situations in which decode errors occur.

Thus, a discrete channel of the new model was practically created, in which each error of an L-bit q-ary symbol is equal to the error probability of all its other (q – 1) symbols.In this case, the probability of the occurrence of each situation, leading to a decoding error, can be easily calculated, which made it possible to provide a predetermined probability of correct reception of information [2]. The author substantiated the length of the q-ary character L equal to 32 bits, at which p is guaranteed not worse than 10 ^–9 .

The current tendency to improve the accuracy of processing information flows is objective, which requires a revision of the requirements for the guaranteed probability of errors in received data after decoding downward to 10 ^–9 from the usual today, in most cases, 10 ^–6 .

Such an increase in the reliability of information is needed today in control systems when transferring target coordinates to high-precision weapons, when processing and storing large amounts of data (big data), commands for the use of special weapons, UAV control, to protect information when transferring public keys in a common network environment, identification “friend or foe”, transmission of information in the decameter wavelength range, etc.

The principle of localization of a correctly accepted sequence, using, among other things, some of the provisions of the modern theory of linear binary codes [7], is the basis for constructing stochastic codes with error correction.

The multiplicity of errors corrected by stochastic codes has the form t = d – 2 (where d is the code distance) [3]. For most anti-jamming codes, t = d – 1/2.

Optimal parameters of (n, k, q) -codes to ensure the maximum bit rate n / k are related to the channel quality (the probability of distortion of the q-ary symbol p _q ), the maximum multiplicity of correctable errors d – 2 and the code length n by the expression np _q = d – 2.

Stochastic codes have a close relationship between the properties of noise immunity and information secrecy, which allows, with appropriate implementation, to additionally ensure the secrecy and control of the integrity of the transmitted information.

A practical method for such an implementation was proposed by Ph.D. M.A. Ivanov, a specialist in the field of information security. Considering that the procedures for creating secrecy means in our state are strictly regulated and new methods of ensuring secrecy must be specified in the established order, it is proposed to solve these problems in accordance with the requirements of block cipher sizes of the standard GOST R 34.12-2015 “Information technology …Cryptographic information protection. Block ciphers “.

To obtain the necessary additional functions, it is proposed to implement multi-round stochastic transformations as blocks R and R ^–1 (Fig. 1), and to generate stochastic transformation parameters – a multi-output pseudo-random sequence generator (PRSP), which has a two-stage design and is specified in GOST R 34.12-2015 for the implementation of encryption by the gamma method.

Implementation of the proposed data transmission scheme allows to provide universal protection of transmitted data by a single algorithm with a one-time introduction of redundancy.At the same time, the problem of protection against interference by elements of stochastic noise-immune coding is solved, and the secrecy and integrity of information is ensured by other, cryptographic , in fact, direct and reverse stochastic transformation schemes and the requirements for GPSS specified in GOST R 34.12-2015 [5] .

The correcting ability of stochastic codes was tested within the framework of the “Argo” design and development work performed at the VKO Concern (the author performed the functions of the Chief Designer) on an ensemble of four stochastic codes of various lengths (8.2; ​​8.4; 16.7; 16.11), which in the short-wave channel provided the possibility of using adaptation to its states with an increase in the correcting ability of various lengths simultaneously with the signal-code structures of the applied HF modems.

In aviation management, where often only a unidirectional transmission mode with the required guaranteed probability is needed, the use of stochastic error-correcting codes may hold a good prospect. Correction of errors, in principle, contributes to the qualitative improvement of network technologies, primarily in terms of increasing their performance, since the rejection of algorithmic methods of information protection by the method of re-asking when an error is detected and the transition to code-based methods of correction significantly increases the performance of expensive network resources.In addition, with the elimination of time losses for re-request, the data exchange rate in radio networks increases.

Well, and, of course, the ability to programmatically implement two more important information security functions with one code structure – imitation resistance and secrecy – is still unique in terms of the “efficiency-cost” criterion.

Stochastic codes found practical application for work in a short-wave channel in the development of special equipment “Vesna-4M”.

Conclusion

The use of stochastic transformations in the field of integrated information protection has no analogues.

The creation of a new model of a q-ary channel and ensembles of random stochastic codes can be considered an achievement of domestic science, recognized abroad [4] [49]. Their presence made it possible to obtain high guaranteed reliability with optimal data exchange rates for a specific channel condition in a wide class of channels with unpredictable parameters, in particular, in the short-wave range.

During the entire communication session, when the characteristics of such channels can change repeatedly, the use of ensembles of codes ensures stable exchange due to the choice of the code length optimal for each channel state from the ensemble.

The use of a q-ary balanced channel in this range can be a better alternative, and a “free” one, to a special interleaving procedure widely used in shortwave modems. This procedure is undertaken with the aim of converting group errors (error bursts) into single errors, since error bursts are more likely to disintegrate into single errors.

The same code constructs, if necessary, ensure the secrecy of information.

Stochastic codes can take their place for the universal protection of information with minimal costs in advanced control systems of videoconferencing, civil aviation, including radio control channels for manned and especially unmanned aerial vehicles, where a high level of protection against all influences is required without the use of encryption equipment [6] [50 ].

They are effective for protecting information in any data exchange channels, while storing them in the computer memory, for protecting against interception and decryption of traffic in local computer networks [50], as well as when handling information on different types of media.

Public Joint Stock Company “Research and Production Association” Almaz “named after Academician A.A. Raspletin “

Public Joint Stock Company “Research and Production Association” Almaz “named after academician A.A. Raspletina “(PJSC” NPO Almaz “) is one of the most successful enterprises of the Russian defense-industrial complex, a world-renowned leader in the development of the latest anti-aircraft missile systems for anti-aircraft, anti-missile and aerospace defense.

The current geopolitical situation in the world sets before the Russian Federation the task of creating the most effective defense system against any means of attack, both from the air and from outer space.

The goal of the PJSC NPO Almaz staff is to provide the Russian Armed Forces with such equipment, which would exclude the very idea of ​​the possibility of an attack on our country by the mere fact of being put on alert!

The enterprise was founded on September 8, 1947 by the decree of the Council of Ministers of the USSR No. 3140-1028 as the main enterprise for the development of guided missile weapons. The initial topic (anti-ship systems based on a projectile aircraft) soon expanded, and now PJSC NPO Almaz is known primarily for its fundamental developments in anti-aircraft and aerospace defense missile systems (air defense and aerospace defense).

Over the years, systems and complexes of military air defense, sea-based air defense systems, and Moscow’s anti-missile defense systems were developed and put into service. The merit in the development of this technique belongs to the collectives of enterprises – Centers, which now form a single whole with PJSC NPO Almaz.

And all this is not a complete list of the company’s successful developments in the field of air defense and aerospace defense systems, adopted by the army of our country and numerous foreign countries.

PJSC NPO Almaz – protection of the peaceful sky of our Motherland.

Air attack weapons are constantly being improved, the upper limit of the use of air attack is shifting more and more towards near space, making it possible to talk about aerospace means of aggression. Accordingly, it is absolutely necessary to improve the means of protection, the creation of an echeloned defense against attacks, both from the air and from outer space.And today, PJSC NPO Almaz is developing advanced weapons, including a fifth-generation anti-aircraft missile system, which is capable of intercepting all modern and promising air and aerospace attack weapons.

The main condition for successful activity PJSC NPO Almaz is a highly qualified team of employees of the enterprise. The “Diamond Fund” can be called the people who created and polished the edges of the “Diamond”.

Scientific and technical schools under the guidance of such remarkable general and chief designers as A.A. Raspletin, B.V. Bunkin, A.G. Bassistov, V.P. Efremov, A.I. Savin, G.V. Kisunko, A.A. Lemansky, educated hundreds of doctors and candidates of sciences, laureates of the Lenin and State Prizes of the USSR and Russia. Achievements of the company’s specialists were noted by the award of the State Prize of Russia for the creation of new air defense weapons and the prize of the Government of Russia in the field of science and technology.

Today, the enterprise carries out a lot of work with young specialists, applicants and graduate students, which ensures the stable development of the scientific potential of NPO Almaz.

The basis of business success PJSC NPO Almaz – effective management using the most modern design solutions and continuous improvement of technologies in the production of prototypes and serial samples of equipment. The competitiveness of the enterprise is due to the accelerated development of its scientific and technical potential and the highly efficient work of the team of employees.

To create a Unified Air Defense Missile Defense System, a decision was made to consolidate the leading developers of air defense and missile defense systems. After all the reorganization measures were taken in 2010, OJSC MNIRE Altair, OJSC NIEMI, OJSC NIIRP and OJSC MNIIPA merged with GSKB Almaz-Antey (now NPO Almaz), becoming structural divisions – Centers.

The hosts started the meeting more actively, going to
attacking actions from the first minutes of the game segment.In the opening of the match
several dangerous throws were reflected by Melnichuk, closer to the middle of the period to the guests

Middle Eastern countries intend to acquire the ROSC-1 anti-UAV complex – Economy and Business

DUBAI, 17 November./ TASS /. As part of Dubai Airshow 2021, the Almaz Antey East Kazakhstan Concern held negotiations with a number of countries in the Middle East region on the sale of a unique complex for providing bird protection and countering aerial drones for ROSC-1 airports. Vitaly Repin, advisor to the deputy general director of the Almaz-Antey concern, told TASS during the Dubai Airshow 2021 aviation exhibition.

“ROSC-1 is a unique system, the only one in the world. It incorporates elements of artificial intelligence, and it is the only system in the world that can distinguish a small drone in a flock of birds.During the exhibition, negotiations were held. Preparatory work is underway to conclude agreements for the sale of the ROSC-1 complex. But it’s too early to talk about contracts, “he said.

The ROSC-1 complex is made on the basis of a Doppler meteorological locator; it can be equipped at the customer’s request with various destruction systems, including the Volk-18 drone. As Repin said, when the locator detects and identifies the target, then the systems are turned on for the possible interception of control of the drone and landing in the right place.Bird safety involves informing the dispatcher about the presence of a bird on the runway, on the taxiway. Further, there may be the inclusion of special means that can drive away birds, these funds are not included in the complex.

The Dubai Airshow 2021 International Aviation Show takes place from November 14 to 18 in the United Arab Emirates. Russia has prepared a number of world premieres for the air show. Thus, within the framework of Dubai Airshow, flights of the Russian MS-21-310 airliner (with Russian PD-14 engines), the medical version of the Ansat helicopter and the Mi-28NE and Ka-52E combat helicopters are planned.The latter are presented to the international public for the first time. The static exposition of Russian equipment includes a prototype of the Checkmate light tactical aircraft, as well as the Ka-226T and Mi-171A2 helicopters. In addition, a Russian Orion drone is shown.

Almaz-Antey provided the defense with answers to written questions – Rambler / news

The Russian defense concern Almaz-Antey provided the defense in the case of the Boeing 777 (flight Mh27) crash in Donbass in 2014 with answers to their written questions.This was reported by RIA Novosti with reference to the judge.

On Monday, November 1, hearings in the case of the plane crash resumed at the Schiphol specially guarded court complex in the Netherlands.

“The questions of the defense, formulated in writing, were transferred to the expert of Almaz-Antey. Comprehensive answers were provided to these questions, ”said the judge.

In June, the defense accused the prosecutor’s office of distorting the data provided by the Almaz-Antey concern in the Mh27 case.

“The prosecution stated that Almaz-Antey chose not to provide early reports, instead providing new ones that did not take into account their own investigation. This is not the case, ”said lawyer Sabine ten Dusshatte.

The plane crash trial began on March 9, 2020 in the Netherlands. There are four persons involved in it: Russians Igor Girkin, Sergey Dubinsky, Oleg Pulatov and Ukrainian Leonid Kharchenko. Pulatova is represented by an international group of two Dutch and one Russian lawyers.The rest are tried in absentia.

The decision of the Dutch prosecutor’s office not to include in the dossier of the Boeing crash in Ukraine in July 2014 the testimony of a witness claiming that the plane could not have been shot down by a Buk anti-aircraft missile system raises serious questions. This was stated on Monday at the hearing by the lawyer Sabine ten Dusshatte, representing the interests of Oleg Pulatov, who is one of the four defendants in the Mh27 case.

According to her, we are talking about the witness S45 who served in the 53rd anti-aircraft missile brigade of the Russian Federation, who was near the crash site of Boeing and who, in an interview with representatives of the Joint Investigation Group (JIT), explained why the plane could not be shot down by the air defense missile system “Beech”.The prosecutor’s office, ten Dusshatte stressed, decided not to include his testimony in the case file as not relevant to the case.

“It is unclear why the prosecutor’s office decided to withhold this information,” the lawyer said. “This information is extremely important for the case.”

More broadly, she stressed, “this raises questions about what criteria the prosecutor’s office uses to assess the relevance of information and how other data at the disposal of the prosecution are assessed.”

“That is why we requested access to the entire volume of information that is at the disposal of the prosecutor’s office,” said ten Dusshatte. came to the attention of the court and the defense. ”

The protection has been denied such access several times already.

According to Dutch law, the prosecutor’s office must provide the court with documents and materials that not only confirm the guilt of the accused, but are also exculpatory.

Interrogation of Sergei Muchkaev

Ten Dusskhatte stated that the court should continue its attempts to interrogate Sergei Muchkaev, who commanded the 53rd anti-aircraft missile brigade based in Kursk in the summer of 2014, as a witness. Earlier, Judge Hendrik Steinhuis said that the investigator did not receive a response from the Russian side to the corresponding request; in the judge’s opinion, it would hardly be possible to interrogate Muchkaev by the set deadline – December 1 of this year.

For her part, ten Dusshatte called on the court not to abandon attempts to question him as a witness.”The importance of his testimony can hardly be overestimated,” she said.

A Malaysian Airlines passenger Boeing -777, performing flight Mh27 from Amsterdam to Kuala Lumpur, crashed on July 17, 2014 in the Donetsk region of Ukraine, killing 298 people – citizens of 10 countries. The JIT announced in June 2019 that it had identified a group of four individuals suspected of involvement in the incident. These are the former head of the Donetsk People’s Republic militia Igor Girkin (Strelkov) and his subordinates Sergey Dubinsky, Pulatov and Leonid Kharchenko.The trial over them began on March 9, 2020, they are accused of allegedly delivering a Buk anti-aircraft gun to Ukraine from the territory of the Russian Federation. The trial of all the accused is being held in absentia; Pulatov’s interests are represented by two Dutch lawyers.

Russian officials have repeatedly expressed lack of confidence in the results of the JIT, which conducted the criminal investigation of the Mh27 case, pointed out the groundlessness of the prosecution’s arguments and the unwillingness to use Moscow’s findings in the course of the investigation.

A number of witnesses in the July 2014 Boeing crash in Ukraine will not be available for questioning anytime soon. This, in particular, applies to Sergei Muchkaev, who commanded the 53rd anti-aircraft missile brigade based in Kursk, Judge Hendrik Steinheis said at a hearing on Monday.

According to him, the investigator recently presented his report on the progress of the investigation into the criminal case of the Boeing crash in Ukraine. The document outlines the progress made and also states that some of the witnesses cannot be questioned.

This, in particular, applies to Sergei Muchkaev, who in the summer of 2014 commanded the 53rd anti-aircraft missile brigade based in Kursk, Steinheis said. As the judge noted, the investigator sent a corresponding request to the Russian authorities and the necessary clarifications. “So far, no response has been received,” he stated.

Ukraine and the European Union (EU) called on Russia to “admit responsibility” for the crash of the Malaysian Boeing 777 that crashed in Donbass in 2014.A joint statement by Kiev and Brussels on the results of the bilateral summit was published on the website of the office of the President of Ukraine.

The sides called on Moscow to continue trilateral negotiations with Australia and the Netherlands, as well as “to admit its responsibility and make every effort to bring those responsible for the downing of flight Mh27”.

The plane crash with the Malaysian Boeing took place on the territory of Ukraine, so it is inappropriate and unacceptable to call on Russia to take responsibility for the plane crash.This was stated by the press secretary of the President of the Russian Federation Dmitry Peskov to reporters during a conference call.

“To be honest, I haven’t had the opportunity to get acquainted with this yet, but again such calls are absolutely inappropriate, unacceptable. They are unacceptable, because after all, this tragedy took place in the skies over the territory of Ukraine, ”said Peskov.

Russian Foreign Minister Sergei Lavrov said that Moscow provided all available data on the Malaysian Boeing 777-200ER that crashed in Ukraine.Kiev, he said, is deliberately hiding important information. The head of the Russian diplomatic mission announced this at a press conference following his visit to New York for the 76th session of the UN General Assembly.

We about the Malaysian Boeing provided all the data from the radars, and much more. The Ukrainians refuse to give data from the radars, allegedly they all turned off for the period of this catastrophe, they refuse to provide the dispatcher’s negotiations from the plane, ” Lavrov admitted.

The decision on the crash in the east of Ukraine of a Boeing 777 aircraft of Malaysian Airlines will be made by the end of 2022.According to TASS, this was stated by the presiding judge Hendrik Steinhuis.

According to him, this can happen on September 22, November 17 or December 15, 2022, it is on these dates that meetings are scheduled at which a final decision can be made. According to the drawn up schedule, the prosecutor’s office will be able to issue an indictment in mid-November or early December of this year, and the defense side will be able to give its answer in March next. The last block of hearings will start in June 2022.

“Usually, the court makes a decision two weeks after the end of the hearing. However, in such a voluminous case, this is impossible. At this stage, it is impossible to say how long it will take the court to reach a verdict,” the judge said, explaining why three are reserved for a verdict. dates.

He also informed that the court in the Netherlands had attached to the case a number of documents obtained from the investigating magistrate.

“This is the content of conversations with three witnesses, a report by experts from the Institute of Forensic Science in the Netherlands on comparative speech analysis and a number of reports from the Royal Military Academy of Belgium, which were available to the prosecutor’s office, but were not previously included in the dossier,” Steinhuis said.

Club Almaz on Channel 1. Self-defense heading.

For 10 years now, since 2008, the Almaz club has been an expert on the first channel in the “self-defense” section. The program is aired in the Good Morning program. The expert is the founder of the club, self-defense expert Mikhail Almaz. The program deals with self-defense in a broad sense. This is protection not only from physical attacks, but also various kinds of scams and fraud.

Filming takes place in Moscow.This time we analyzed the current Internet frauds. Everyone can fall into the cunning networks of swindlers who adapt to modern realities. The deception pattern is often similar and has not changed for decades. It doesn’t matter what topic, but scammers always use things like freebies, naivety, and time constraints.

For example, one of the situations is the return of the rights of those deprived of drunk driving. As it turned out, it is quite easy to obtain information about a person who has been deprived of his rights in court.Then they find him on social networks, give some details, offer help for a certain amount. Yes, that’s just to return the rights after a court decision is practically impossible thing. And, if a person buys into this venture, then he will lose money, but he will not return the right.

We don’t want to make a spoiler, for those interested, watch the “good morning” program, which is aired on channel 1 on weekdays. And under the heading “self-defense”, this and other stories will certainly be shown. The question is, what does this have to do with self-defense training when it comes to cheating? However, self-defense is a broader concept than is commonly believed.
