Chapter 1141: PTRR-39 anti-tank gun

The German wheeled infantry fighting vehicles were harvesting the lives of Soviet soldiers. At this time, the Soviet soldiers fell like sheep under the German machine guns.
The scene was very brutal and very bloody.
A machine gunner crawled in the grass, trying to use his machine gun to greet the Germans, but when his machine gun was about to fire, the 40mm tank gun on the opposite side fired at him. Several shells were on him. The explosion around him broke him apart.
Not all people were brave enough to fight the war. After the deadliest group was killed, the rest of them all began to run backwards involuntarily.
There are fewer and fewer people resisting, but this does not mean there is no.
Ostrov is one of them.
He was originally walking behind the team. After the German tank appeared in front of him, he knew that the situation was not good. If he turned his head and ran at this moment, he might run away.
But he didn't. He still remembered his mission.
He put down his long rifle from his back, opened the front bipod, and pointed the thick muzzle at the front. The huge was just right by him. withstand.
This gun is totally different from the Monashin Gan rifle equipped by the Soviet infantry. In terms of length, even without a bayonet, it has reached a terrible length of 1.7 meters, almost the same height as a person.
Therefore, this gun cannot be carried behind your back. Almost all of them are carried, just like carrying a bamboo pole. The muzzle faces the sky and looks quite awe-inspiring.
This is the anti-tank weapon of the Soviet infantry, the anti-tank gun.
Individuals dealing with enemy tanks are always an unavoidable problem. The German solution is to use recoilless guns, while the Soviet solution is anti-tank guns.
This weapon has actually been invented during World War I when the Germans first invented it.
If you want to penetrate the opponent's armor, you need enough energy. For guns, one is to increase the caliber and the other is to increase the length.
Increasing the caliber can increase the weight and charge of the warhead, thereby increasing the kinetic energy of the warhead, and increasing the length of the barrel can increase the work of the gunpowder, thereby increasing the initial velocity of the warhead.
The anti-tank gun is such a thick and long thing.
The Soviets have never given up research on anti-tank guns. In the past few years, they have put forward 15 designs for anti-tank rifles with calibers ranging from 12.7 mm to 25 mm.
After conducting a large number of experiments and investigations, the proposal put forward by the Soviet Union Light Weapons Range Research Group finally won the welcome of the Soviet Union's top leaders. (NIPSVO is the group of people who designed the 14.5 high-speed bullet)
Their product is the current PTRR-39 anti-tank gun. The caliber of this gun is 14.5 mm, which is a very compromise solution. If the caliber is too large, the recoil on the human body will be quite large, and it will produce human life. Threatened.
If the caliber is small, the power is not enough.
After being trial-produced, this gun penetrated the 20 mm armor placed at 20 degrees at 500 meters and 30 mm armor at 100 meters using only ordinary bullets.
After using a special warhead, it can reach a penetration depth of 50 mm. For an anti-tank gun, this is already quite sky-defying.
Historically, this type of gun was not mass-produced, because Germany fooled the Soviet Union, and their armor was not 50 mm thick. Historically, the German No. 3 and No. 4 were really not very solid.
But now it’s different. The German tank has never been able to be penetrated. It is simply a sharp sword hovering above the Soviets. The Soviets thought of various ways, such as the current anti-tank gun, although it cannot penetrate. The armor of the German main battle tank is, after all, a good weapon of great power. Therefore, although the production is complicated, the troops are still equipped in small batches, so that the troops will not be caught off guard in front of the enemy's tanks.
If you can’t penetrate the opponent’s main armor, you can also hit other things, such as the slot observed in front of the tanker. If you aim and hit, 14.5mm bullets can fly in. For example, if the opponent’s track is broken, so It's okay, even when you go around, hit the side and tail of the opponent, it is possible to penetrate, and you will not be helpless.
Now, to deal with the German wheeled armored vehicles, let alone, absolutely no problem!
Ostrov squinted his eyes, he held his breath, pointed at the wheeled armored car that was moving towards him, and pulled the trigger.
"Hum!" The 14.5mm armour-piercing incendiary flew out of his muzzle. Although the muzzle had been equipped with a retractor, there was still a huge recoil. For a moment, his shoulders seemed to have been smashed. It hurts to pat it abruptly with a spade~EbookFREE.me~.
He got up, holding his rifle and ran.
In many military novels, snipers are too awesome. Holding Barrett’s sniper is even more awesome. In fact, the sniper has to be added with two words before it, called cannon fodder sniper!
No matter how powerful the sniper is, are there any artillery? If you hit someone with a gun, they will hit you with artillery. Your position has long been exposed!
Especially for large-caliber rifles, the recoil is quite large. If there is no muzzle brake, the recoil will knock people away.
It sounds mysterious, but in fact, the muzzle brake is very simple. At the front end of the muzzle of this anti-tank gun, there is something like a horizontal plug, which is much wider than the barrel and has a small hole in the middle. Let the bullets come out.
At the same time, when the bullet is shot out, the expanded gunpowder gas behind will also rush out, and a large part of it will impact the reflecting surface of the device, and make part of the air flow deflected and discharged through the side holes, thereby providing control. Retreat.
Then, the gas did lighten the recoil of the gun. At the same time, when the gas spreads to both sides, it also blows up things on both sides.
For example, at the location where Ostrov was just now, the dust flew up several meters! A soldier who has survived the test of war can lock his position immediately.
Run, run quickly, if you run slowly, there will be a dead end!
The sniper must have very good physical fitness. In addition to carrying this big gun, he also has to run fast!
"Boom!" At this moment, an explosion sounded hundreds of meters away, and he successfully killed an infantry fighting vehicle!
But at the same time, other infantry fighting vehicles also found his hiding place. In an instant, two or three infantry fighting vehicles, not stingy with ammunition, and 40 mm shells flew out of the muzzle, toward Shoot in the direction of Ostrov!
