The Soviet Union's research on anti-tank guns began in 1936. It can be said that it was the Spanish civil war that put heavy pressure on the Soviets on anti-tank weapons.

Afterwards, the Soviet design unit designed a total of 15 anti-tank rifles with different calibers from 12.7 mm to 25 mm. After a lot of investigations and experiments, the Soviet Light Weapons Range Scientific Research Group's plan finally came to an affirmation.

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

It is 1.7 meters long, of which the barrel is 1180mm and weighs about 24kg. It uses ordinary bullets to penetrate 20mm armor placed at 20 degrees, and even 30mm armor is penetrated at 100 meters.

However, in the history of later generations, this gun did not shine and was produced in complex ways. At the same time, the Soviets felt that it was overpowering, so this gun was only produced very little, and it was finally cut.

As a result, after Barbarossa's plan, the Soviets discovered that they did not have a suitable anti-tank gun in their hands! As a result, they hurriedly got the PTRS-41 rifle, which was considered a convenient weapon.

Now, during the Spanish Civil War, the sudden appearance of the Black Panther tank surprised the Soviets, so they tinkered with this anti-tank gun and sent it to the Spanish battlefield, preparing to test its performance through the battlefield.

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

Any armored soldier hopes that his tank is thick enough to withstand the opponent's attacks and will never want it to be penetrated by the opponent!

Now that Guderian was found such a weapon from the Soviets, he was very cautious.

So, in the square of the railway station, where the fierce fire broke out, we found a piece of open space and tested this anti-tank gun.

The one who undertakes the test mission is Ilia, the machine gunner in the armored grenadier. Before he became a machine gunner, he was an anti-tank gun shooter and had rich experience in using Germany's own Mauser 13.2mm anti-tank gun.

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

"Bang!" As he pulled the trigger, the gun body trembled suddenly. The columnar multi-chamber retractor in front of the muzzle sprayed gas backwards, and dust was everywhere.

Although rubber cushioning pads were added to the butt stock, Ilia still felt a huge force hitting his shoulders. This thing can only be used by the strongest warrior!

In many military novels, the 12.7mm Barret rifle is quite admired, believing that it is an omnipotent weapon and is the trump card in the hands of a sniper. In fact, the word cannon fodder is added to the front of the sniper.

Cannon fodder sniper! No matter how well the sniper hides, as long as you shoot, you will expose your target. This is because of the muzzle-rejection device!

In order to offset the recoil, you need to spray some gunpowder gas backwards. These gases will cause a lot of noise! ​​The next moment, they will be discovered by the opponent and then be attacked by artillery fire!

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

300 meters away, a 20mm thick piece of armor clamped the 14.5mm bullet in the middle! The warhead has passed, but the bullet body is still embedded inside!

"It seems that the Soviets didn't realize how hard our armor was." After receiving the report, Guderian finally breathed a sigh of relief.

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

How much depth of armor can be penetrated by a tank is related to the quality of the armor. Germany does not have to worry about rare metals now. It uses the best armored steel, and it is all cold-rolled, far exceeding the cast steel of the Soviets. Therefore, the Soviets could penetrate 20mm armor placed at 20 degrees, and when they arrived in Germany, it became impossible to penetrate!

Even in the late period of World War II, Germany lacked rare metals, and relied on its advanced scientific and technological strength to adopt carburizing technology, which is commonly known as the surface hardening process in later generations, and the hardness is also very good.

"Next, let's test the depth of 100 meters." Guderian said: "Add the armor thickness to 30 mm."

The Black Panther 2 tank is a simplified Black Panther tank with only a 20-ton weight. Its gun has the weakest armor behind it. If it is converted into tilted armor, it is equivalent to a thickness of 30 mm. Now, it is necessary to test whether this tank can withstand the impact of this anti-tank gun from behind!

After preparation, the second experiment began again.

Now, it is already past ten o'clock in the evening, and almost everyone is not sleepy. They look at their armored steel and can withstand the attack of the latest anti-tank guns like the Soviets at a distance of 100 meters.

In other words, even in street fighting, the opponent cannot pose a fatal threat to his tank. At most, it can hit tracks, load-bearing wheels and other positions, which may cause mechanical failure.

Even Black Panther 2 tanks can withstand it, and Black Panther 1 tank, there is no problem.

This question is not a problem, so there is no need to worry about it.

Let's go to bed. When the Northern Army comes tomorrow, our side will continue to attack!

Just as Guderian was about to leave, Scherner hurriedly ran out of the warehouse: "Teacher, we have also found these things in the warehouse!"

A wooden box had been pried open with a crowbar, and inside it were yellow and orange bullets!

The shell is made of best copper, but the bullet is not shiny and a little black.

The one I just tested was just an ordinary 14.5mm armor-piercing bomb, and the one I contained in this box was obviously a special armor-piercing bomb!

"Try it!" said Goodrian anxiously.

"Bang!" As the gunshots, 100 meters away, the 30 mm armor plate was penetrated in response!

"Switch to 50mm thick!" Goodrian continued to shout.

"Bang!" The 50mm thick armor plate was also penetrated!

“Land incline!”

Now, it was finally blocked!

Seeing all this, everyone's face looked ugly.

This means that if your Black Panther 2 tank enters street battle, it will be penetrated by this anti-tank gun from the side! Only your 30-ton Black Panther 1 tank can withstand the attack of this bullet. In other words, if you go to street battles in the future, Black Panther 1 will be the main force!
Chapter completed!
