Ballistic Silence of Special Years

Chapter 677 Simulation (2)

Rushing to the elevator, Qiao Li quickly pressed the up button, wishing she could teleport to the door of the textile company and rush in again.

Now is a good opportunity. Although the murderer cunningly asked the hostages to get food and water and escaped the sniper's sniper, but he used children as threats to control the female hostages, but he also left hidden dangers for himself.

As long as you go in now and get close to the plane, at the distance just now, Qiao Li is confident that she can kill her with one blow.

However, as soon as he got out of the elevator door, Zhong Jun's voice came from the earphones.

"Joe, stop! Stop! The time is lost!"

Qiao Li couldn't help but anxiously glanced at the company's gate, then walked quickly to the special police who were stuck behind the wall outside the gate, and asked in a low voice, "What's going on inside now?"

The special policeman turned his head, made a silent gesture, and then handed a PAD in his hand to Qiao Li.

The internal screen of the company is on the PAD, and the scene inside can be seen through the special police hose spy mirror, and the content of the company's internal monitoring probe can also be called up simultaneously.

I saw that the female hostage had already got the food and water and returned to the murderer. She had to do this because her daughter was still in the hands of the murderer.

The current situation has returned to the previous one again, the female boss became a hostage again, the child was grabbed by the collar, hugged the mother's leg and looked around in horror, looking pitiful and helpless.

In an industrial area about two kilometers away from the cloth market, Li Zheng was lying on the roof, aiming at the fourth floor of a controlled factory opposite.

This is his request. Set up a scene that is roughly similar to the scene, use the power of the police to find glass with the same material and thickness as the unapproved market windows, and find a card slot desk with the same style as the company. The fourth floor of the factory building is arranged in roughly the same scene as the hostage-taking scene in the cloth market.

Fang Bin used all the resources.

The Criminal Police Brigade, the Patrol Brigade, and the police station worked together to find the management of the cloth market and call out the glass specifications used in the decoration that year. At the same time, all the owners of the furniture city in L City received phone calls from the police and WeChat. The picture, the question is only one sentence - do you have a card slot desk of the same style? !

Soon, the table and glass were delivered, and the patrol team was responsible for ensuring the on-site construction.

According to the general situation within that company, a simulated scene was set up, and only a small shooting angle and area could be seen on the roof of Li Zhengyuan's building.

Compared with the cloth market, this place is already extremely close to the scene.

"That's all I can do in a short time."

Fang Bin looked at the factory opposite.

"This distance is a bit far, 30 meters more."

He was worried that the 30 meters more distance would affect Li Zheng's performance.

Li Zheng adjusted the handwheel calmly, and said, "It's okay, the main thing is the height and angle, just roughly the same, and the distance doesn't have a big impact."

After adjusting the aiming parameters of the sniper rifle, Li Zheng began to use the gun...

Two plastic mannequins placed in the corner of the factory are placed one behind the other in a state of hostage-taking.

Under the 8x magnification, Li Zheng can clearly see the situation behind the glass.

In fact, for a sniper of Li Zheng's level, it is easy to focus on a target the size of half a head at 180 meters.

And he has received corresponding shooting training through the window.

In the underground shooting range of Unit 203, there are all kinds of strange equipment. In the wild shooting range, there are also vehicles such as trucks and SUVs. The simulation is this kind of long-distance penetration. The task of killing targets through car window glass and building glass situation.

Under such a height difference, how many degrees to correct and where to aim are all very particular.

When he was at Base 203, Li Zheng learned at least two aspects of glass-related sniper subjects——

One is as a sniper behind glass shooting distant targets.

The second is as a sniper to shoot at the target behind the glass from a distance.

Therefore, Li Zheng is no stranger to this kind of shooting. He was helped by Lao Sun when he was in the 203 base, and he raised some points and learned a lot of good things.

At that time, the instructor and Lao Suntou in 203 told Li Zheng that when using a sniper rifle to shoot at a target behind the glass, the sniper rifle with a caliber above 7.62mm is the first choice, and the shooting position should try to make the ballistic trajectory perpendicular to the glass.If you only need to kill the target, the larger the caliber, the better, because the larger the caliber, the less affected by the glass; if you want to rescue the hostages, try to choose 7.62 or .308 caliber. If you have a large caliber such as .50 Even if the sniper bullets didn't hit the hostages, they would still cause some collateral damage.

Secondly, when using a 7.62mm sniper rifle to shoot at a target behind a 5mm thick ordinary flat glass, when the shooting angle is within 30° of the incident angle, the projectile will basically maintain integrity after penetrating the 5mm glass; as the incident angle increases, the projectile will penetrate the glass. There will be a certain amount of horizontal offset after that, but the offset is within an acceptable range.

However, when a 5.8mm sniper rifle shoots at a target behind a 5mm-thick ordinary flat glass, the projectile will disintegrate. Although the offset is still relatively small, the offset and disintegration of the warhead after the small-caliber ammunition penetrates the glass will appear to be correct. Possibility of injury from hostages who get too close.

In addition, thicker tempered glass will intensify the damage to the projectile and reduce the kinetic energy of the projectile, but the projectile that penetrates ordinary tempered glass (excluding laminated glass) within the standard range distance is enough to kill targets without protective equipment. There is no need to worry about things like the lack of kinetic energy of the warhead and the inability to penetrate the skull.

In addition, if the hijacker is in a car, he will usually be closer to the glass. The closer the target is to the glass, the less difficult it is to snipe.

But the "radiations" on the unbreakable safety glass will make it very difficult to shoot again.

If the hijacker is on a school bus, bus or train, he may be far away from the glass, which increases the chance of deflecting the bullet.

When shooting through non-safety glass, snipers must be aware of the possibility of a "shatter effect" in which sharp shards of glass may be thrown towards hostages and abductors inside the home.

This is why a police sniper in a certain place shot a hijacker on a bus at a distance of 30 meters a year ago, but the warhead deviated and injured the hostage, which caused a sensational news.

Generally speaking, Li Zheng felt that the pressure of this sniper mission was not too great.

Just out of caution, he asked to set up a mock site for test shooting.

Anyhow, it involves human life and needs to be treated with seriousness and caution.

bah—

Li Zheng hit the first shot quickly.

Afterwards, the opposite side was inspecting the target.

The image was quickly sent to the mobile phone, and Fang Bin's eyes lit up when he saw it.

The bullet hit the back of the hijacker's head on the left side, but the power was enough to lift the cover of the back of the head, and he was undoubtedly dead.

Li Zheng looked at the point of impact, shook his head and said, "No, I aimed at the temple... It seems that the angle is relatively small, and the pattern on the glass has a refraction effect on the target on the window. Change the glass again and do it again. "

Fang Bin didn't dare to refute, so he hurriedly ordered someone to change the glass.

After the new glass was installed, Li Zheng changed his shoulder to aim and fired two shots.

bah—

bah—

Fang Bin was startled.

The interval between these two shots was very short. He saw that Li Zheng aimed with his left eye this time, and pulled the trigger with his left hand. At the same time, his right hand loaded the gun like lightning.

Fang Bin had never seen anyone shoot like this.

He hurriedly picked up his mobile phone and shouted "Target inspection."

Soon, the design effect screen appeared on the phone.

Both hits, all in the head.

One shot hit the temple, and another shot hit a little bit above, directly piercing the Tianling Gai.

Li Zheng looked satisfied this time, nodded and said, "Success, let's go!"

After finishing speaking, he got up to pack his guns and ammunition and then went downstairs to leave.

　It is said that it will continue for a longer time.

　　I ran to three cities today, went back to my hometown after sweeping the tomb, and accompanied my wife on some official business. I just got home and fulfilled my promise. Let me rest early tonight, and I will give you the third watch tomorrow.

　　It's worth giving a monthly pass for being so diligent, right?
