The study of anti-tank guns in the USSR began in 36, and it can be said that it was the Spanish Civil War that put heavy pressure on the Soviets regarding anti-tank weapons. Pen ~ fun ~ pavilion www.biquge.info

After that, the Soviet design unit designed a total of 15 anti-tank rifles of different calibers from 12.7 mm to 25 mm, and after a large number of investigations and experiments, the plan of the Soviet scientific research group on the range of small arms was finally confirmed.

This is a 14.5 mm anti-tank gun codenamed PTRR-39.

It is 1.7 meters long, with a barrel of 1180 mm and weighs about 24 kg. At a distance of 500 meters, a normal bullet penetrates 20 mm of armor placed at 20 degrees, and at 100 meters, it penetrates 30 mm of armor.

However, in later history, this gun did not shine, the production was complicated, and at the same time, the Soviets felt that it was too powerful, and only a small number of this gun were produced, and finally it was cut.

As a result, it was only after the Barbarossa plan that the Soviets found out that they did not have a suitable anti-tank gun in their hands! As a result, in a hurry, the PTRS-41 rifle was made, which can be regarded as a handy weapon.

And now, in the Spanish Civil War, the sudden appearance of the Panther tank surprised the Soviets, so they tinkered with this anti-tank gun and sent it to the Spanish battlefield, ready to test its performance through the battlefield.

But now, before this test has begun, it has already been captured here!

Any armored soldier wants his tank to be thick enough to withstand the blows of the opponent, and absolutely does not want to be penetrated by the opponent!

Now that this weapon of the Soviets was discovered, Guderian was very cautious.

So, on the square of the railway station, where a fierce exchange of fire had just broken out, find an open space, and the test of this anti-tank gun began.

The test was tasked with the Panzergrenadier machine gunner Ilya, who had been an anti-tank gun shooter before he became a machine gunner and had extensive experience with Germany's own Mauser 13.2 mm anti-tank gun.

The target was placed three hundred meters away, and under the light, everything was clear.

"Bang!" As he pulled the trigger, the barrel of the gun shook backwards, and the columnar multi-chamber brake in front of the muzzle spewed gas backwards, and there was a cloud of dust all around.

Despite the rubber cushion added to the back of the stock, Ilya felt a tremendous force hitting his shoulder, something that only the strongest warriors could use!

In many military novels, the 12.7mm Barrett rifle is quite admired, thinking that it is an omnipotent weapon and a trump card in the hands of snipers.

Cannon fodder sniper! No matter how well a sniper hides, as long as he shoots, he will reveal his target, and that's because of the muzzle brake!

In order to counteract the recoil, you need to spray some gunpowder gas backwards, and these gases will make a lot of noise! The next moment, it will be discovered by the other party, and then it will attract a counterattack covered by artillery fire!

Now, this 14.5 mm anti-tank gun is in the same state.

300 meters away, a piece of 20 mm thick armor, with that 14.5 mm bullet caught in the middle! The warhead has passed, however, the body is still embedded in it!

"It seems that the Soviets simply did not realize how hard our armor is." After receiving the report, Guderian finally breathed a sigh of relief.

This piece of armor is placed vertically, and it is not tilted, and the opponent's bullets cannot penetrate it completely, so on the battlefield, there is no need to worry about being observed by anti-tank men with this rifle, even in the rear!

How deep the armor can the tank penetrate is still related to the quality of the armor, Germany now does not have to worry about rare metals, the best armor steel is used, and it is all cold-rolled process, far more than the casting steel of the Soviets, so the Soviets can penetrate the 20 mm armor placed at 20 degrees, and here in Germany, it becomes impossible to penetrate!

Even in the late stage of World War II, Germany lacked rare metals, relying on advanced scientific and technological strength, the carburizing process, which was often referred to as the case hardening process in later generations, was also very good.

"Next, let's test the penetration depth of 100 meters again." Guderian said: "Increase the thickness of the armor to 30 millimeters. ”

The Panther 2 tank is a simplified version of the Panther tank, weighing only 20 tons, and its armor behind the gun is the weakest, and the inclined armor is equivalent to a thickness of 30 mm.

After the preparations, the second experiment began again.

Now, it was already ten o'clock in the middle of the night, and almost all of them were not sleepy, and they looked at their own armor steel, which, at a distance of 100 meters, was able to withstand the blows of the latest anti-tank guns of the Soviets.

That is to say, even in street battles, the opponent cannot pose a mortal threat to his tank, at most it is to hit the tracks, load wheels and other positions, which may cause mechanical failure.

The Panther 2 tank can carry it, and the Panther 1 tank has no problem.

This problem, not a problem, no need to worry about it.

Wash and sleep, tomorrow when the northern army comes up, you will continue to attack!

Just as Guderian was about to leave, Schellner hurriedly ran out of the warehouse: "Division commander, we are in the warehouse, and we have found these things!" ”

A wooden box had been pried open with a crowbar, and inside was a series of yellow, orange and orange bullets!

The shell is made of fine copper, but the warhead is not shiny and somewhat blackened.

What has just been test-fired is just an ordinary 14.5 mm armor-piercing projectile, and what is contained in this box is, obviously, a special armor-piercing projectile!

"Try it!" Guderian said anxiously.

"Bang!" With the sound of the gun, 100 meters away, the 30 mm armor plate was pierced!

"Change to a 50mm thick one!" Guderian's face was ugly, and he continued to shout.

"Bang!" 50 mm thick armor plates, also penetrated!

"Tilt it!"

Now, it's finally blocked!

Looking at all this, everyone's faces were ugly.

This means that your Panther 2 tank, if it enters a street fight, will be pierced by this anti-tank gun from the side! Only your own 30-ton Panther 1 tank can withstand the blow of this bullet, that is to say, in the future street battles, you must send the Panther 1 as the main force!

"Immediately telegraph the discovery here to General Ciric!" Guderian said.
