Double-check the copper core bullet.

Good guys, it's all shattered.

It feels as if it has hit the highest level of protective steel.

The warhead is already completely deformed.

This is not surprising.

Oddly enough, what about its kinetic energy?

How is its kinetic energy disarmed? Why didn't it poke into the plaster cast?

The biggest drawback of soft body armor is that it cannot effectively disperse the kinetic energy of the bullet quickly, resulting in the warhead being blocked and continuing to move forward.

It will pull the body armor into the target's body to a depth of tens of millimeters, thus indirectly causing damage to the human body.

If the bullet is powerful enough, it can cause internal bleeding to the target, and may even lead to death.

This is also the reason why the high-end body armor is all hard and not soft.

The protective performance of soft body armor is insufficient!

However, Wang Buan completely subverted this.

The soft body armor he developed and produced has also reached the fourth level of protection.

According to the relevant national standards, as long as it can defend against the close-range shooting of copper-core bullets with 79 micro-punches, it is considered to have reached the four-level protection standard.

This is a height that soft body armor has never been able to reach.

From this level, all body armor needs to be inserted into steel plates.

From this level onwards, all body armor will become heavy and difficult.

"Chief Engineer Wang, what is the principle?"

"Trade Secrets. ”

"Understood. ”

Then they asked no more.

They don't need to know about this kind of trade secret.

In fact, it's all thanks to memory metal. The bullet of the seventy-nine micro rush successfully triggered the counterattack of the memory metal.

At the moment of impact, the memory metal dented. However, the dent is less than a millimeter, and it is already an automatic rebound. It used its own rebound energy to dissolve all the energy of the warhead.

In this way, the warhead naturally cannot cause any fatal damage to the plaster cast on the back of the body armor.

The effect of memory metal is indeed very magical. Unfortunately, the production is too small.

For the time being, it can only be used as body armor.

"Forget it. ”

"Let's use MP5!"

"Good. ”

The big star MP5 is on the field.

When it comes to submachine guns, only two in the world are the most famous.

The first one, an MP5 from Germany.

The second, Uzi from Israel.

Both submachine guns had their own characteristics. The amount of equipment is also very large.

In the past, the police Flying Tigers in Xiangjiang used MP5. After returning to the motherland, a considerable number of MP5s were still preserved.

It must be admitted that the Germans have always been the most sophisticated in their weapons. The performance is very good.

No matter what kind of troops, MP5 is a very good choice.

"Come, Chief Engineer Wang, will you try it?" Liang Ge said with a smile.

"Okay!" Wang Buan agreed without thinking.

Playing with guns? That's definitely going to be loved.

It's just that there was no chance before.

During military training, only five rounds were fired.

Before they could figure out the trick of target shooting, all five bullets had already been fired. I can only regret it.

"Will you shoot?" Cheng Kailong said cautiously, "Do you want to teach." ”

"I don't want you to teach. Wang Buan shook his head stupidly.

Well, he's just holding grudges.

If you don't let me see the beautiful flight attendant, I'm just holding a grudge!

"I'll teach you. "Ding Chen came up.

"Okay. Thank you. Wang Buan immediately changed his attitude.

Ding Chen seriously explained the basics of shooting.

Wang Buan's comprehension is not bad.

It didn't take long to get the hang of it.

Raise your gun.

Shoot.

"Da Da Da!"

"Da Da Da!"

MP5 is definitely a good gun.

It has very little recoil. Makes shooting very well controlled.

At the same time, its grip, as well as the ergonomics of the entire gun, are very scientific. Great for Asians.

If it's a Chicago typewriter or something, heavy and hard, it is estimated that Asians will not be used to their size.

Spot shot.

Long point shot.

Short point shot.

A magazine runs out quickly.

Ding Chen obviously wanted to make Wang Bu'an enjoyable. Immediately another magazine was replaced.

"Thank you. ”

"No, I don't. ”

Wang Buan also did not refuse to come.

After thanking him, he continued to shoot. We must make up for all the previous regrets.

However, shooting is not a pleasant thing to do.

Even if the recoil is small, it's hard.

After firing three magazines in a row, Wang Buan felt a little soreness in his arm.

That's enough.

Almost.

Seeing that Ding Chen still had to change the magazine, he hurriedly shook his head.

Take a break.

Take a break.

He couldn't hold it up with such continuous shooting.

Fortunately, it was a submachine gun. If it's an assault rifle, three magazines in a row, the recoil is enough for him.

Ding Chen motioned to everyone

All firearms were taken away for safety.

Check the condition of the individual body armor.

Good.

There is no damage.

There is almost no mark.

But the dummy behind the body armor seems to be a bit of a problem.

There were many depressions in its skin. The depth is about two millimeters. This is what the bullets of the submachine gun left behind.

Although, the body armor is to block the warhead. However, the impact of the warhead is still there.

If it's not a dummy, but a living person, it is estimated that it will be more uncomfortable.

However, the result is already ideal.

Because, at a depth of two millimeters, it will hardly hurt the muscles and bones.

Generally speaking, the muscles of the human body are able to withstand such depressions. At most, it feels more painful.

In other words, it has excellent protection. Almost negligible.

It's not easy.

Shots that can protect the MP5 will definitely be famous all over the world.

Because......

The MP5 is definitely not an ordinary submachine gun.

It has almost become one of the iconic equipment of anti-terrorist forces in various countries around the world.

Especially those countries that are unable to produce their own standard weapons. The MP5 submachine gun will almost always be chosen as the first option. The number of equipment it has is very large.

If......

Well, is it if......

Assuming that the terrorists wore the body armor developed by Wang Buan, then it would be a big problem.

The MP5 submachine gun can't do fatal damage to them at all!

Basically, it's not lethal.

Unless it's a headshot.

"Let's change Uzi. ”

"Okay. ”

Soon, Uzi submachine guns came into battle.

Ding Chen raised a handful of Uzi and motioned to Wang Bu'an if he wanted to try.

Wang Buan shook his head.

Don't try it.

It's not fun, actually.

It's nice to experience it.

If you play with guns for a long time, you will probably be tired to death.

Special forces, after all, special forces, are definitely not something that ordinary people can do. Not only does it take hellish physical fitness, but even playing with guns requires 120 points of perseverance.

"You're coming?"

"I'm coming!"

Cheng Kailong personally went into battle.

He picked up two handfuls of Uzi. At the same time, fire was fired.

"Snort!"

"Snort!"

The rate of fire of the Uzi submachine gun was too fast.

A magazine that spits out almost in a second.

Uzi is very lightweight. The grip is also quite special. Therefore, it is the only submachine gun that can be used with one hand, but both hands can be fired at the same time.

It is also almost the fastest rate of fire submachine gun. In a very short period of time, a terrifying rain of bullets can erupt.

More than sixty rounds of ammunition were poured on top of the body armor.

Two magazines are clearly not enough.

Keep shooting.

More than thirty magazines were fired in one go.

Scrutinize.

The result was pretty much the same as guessed.

The power of Uzi is actually inferior to MP5. After all, it's the barrel that's too short.

Its muzzle velocity is only about 320 meters per second.

Of all the submachine guns, it has the lowest muzzle velocity.

More often, the distance of Uzi's action is between a few meters and tens of meters. If it's more than fifty meters, I'm afraid it won't be of much use.

And the MP5 is within 100 meters, and it still has a relatively strong suppression ability. There is also a strong effect within two hundred meters.

Judging by the use of Uzi submachine guns, they are mainly used by close guards.

Their range is basically within 50 meters.

Due to the weaker power of the warhead, the dummy suffers less damage.

In other words, after wearing Wang Bu'an's brand body armor, even if it is a face-to-face shot from an Uzi submachine gun, it can be unharmed.

Of course, a slap in the face doesn't count.

Ding Chen was very satisfied.

Liang Ge was also very satisfied.

Cheng Kailong is also very satisfied.

Obviously, Wang Bu'an's brand body armor has a very good effect.

Weapons such as high-powered assault rifles, sniper rifles, anti-aircraft machine guns, and bazookas have not yet been tested.

However, judging from the current test results, it is already very ideal.

After all, it weighs only three kilograms!

With such a light weight and such good protection properties, it is simply breathtaking.

In the field of body armor, Wang Buan can definitely win the Science and Technology Progress Award.

Of course, maybe he didn't care about any of that at all.

Someone else is a super inventor.

There are so many products in the Tyrannosaurus Rex industry.

The drone of White Feather Whale Technology has made the world even more noisy.

When the situation was at its most tense, the Dingjun Mountain Special Training Camp was also ready to go out to support at any time. Therefore, they are very familiar with Wang Buan.

It would be nice if it could reduce the damage of the assault rifle.

As for complete defense......

It can only rely on metal inserts.

What the?

Don't want metal inserts?

At present, no one's body armor can do this.

"Ninety-five?"

"Eighty-one bar. ”

"Chief Engineer Wang?"

"Let's go first. ”

"Good. ”

Ding Chen waved his hand.

The first to go into battle is the Bayi bar.

The atmosphere at the scene suddenly became a little tense.

After all, this is the real test.

If it passes, it's the best body armor.

If it doesn't pass, it can only be said to be a small regret. But there is no way.

At present, the world's most advanced technology is at this level.

Unless it is to add a metal insert.

"What's the distance?"

"Fifty meters. ”

"Good. ”

Why not a hundred meters?

The main thing is the engagement of modern special forces, which is getting closer and closer.

Fifty meters is a normal distance. Beyond 100 meters, neither side will open fire easily. so as not to expose the target in vain.

From this point of view, the engagement of special forces is indeed very cruel.

After all, it's only fifty meters away!

Once a party is in a passive state of being beaten, there is almost no chance to fight back.

A few gunshots rang out, and several could have been killed.

At a distance of two hundred meters, it is definitely a hundred shots and a fatal blow.

Fifteen years ago, in northern Burma......
