There is no doubt that at a distance of 1,000 meters, the IS-3 easily jumped away from the hard-core armor-piercing shells fired by the 88 guns, leaving a white spot on Shoushan Mountain, which did not cause any damage to it at all. Pen, fun, and www.biquge.info

1000 meters did not break through, continued to advance, advanced 200 meters, that is, 800 meters away, and fired at IS-3.

At 800 meters of straight shooting, the kinetic energy of the hard-core armor-piercing projectile is much higher than that of the 1000-meter distance, but it still cannot pose a threat to the IS-3 on the front, and it has a trace on the plow-blade inclined armor and is ejected. At a distance of 800 meters, the frontal can completely block the hard-core armor-piercing shells of the long-barreled 88 gun.

"Push 500 meters and try!" The bearded man watched from the side, ricocheting at a distance of 800 meters, it was not unexpected, if it could penetrate it, it would be a surprise, 800 meters away, even IS could jump 800 ordinary armor-piercing shells.

The cart with the 88 long-barreled cannon pushed forward, stopped 500 meters away from the IS-3, and pointed at the IS-3 with the barrel cross.

The gunner sloppily stuffed a hard-core armor-piercing projectile into the barrel, at a distance of 500 meters, for a hard-core armor-piercing projectile, the kinetic energy attenuation is not ruthless, if it is 500 meters away to block the 88 long-body gun, the beard will be satisfied.

Tank guns are fired with a trigger, unlike ordinary guns, which are pulled with a gun rope.

The gunner aimed at the front of the IS-3, pulled the trigger, and the old barrel of the 88 gun retreated sharply under the aid of the retreat, the muzzle of the gun spewed flames, and the projectile flew towards the IS-3 with an unrivaled momentum. Almost instantly, the projectile hit the front of the IS-3 with a loud "bell", but was drowned out by the sound of cannonballs.

"Quick, let's see if it's broken." The smoke cleared, and the bearded man stared at IS-3, and his main concern now was whether IS-3 had been penetrated.

"Report, no breakdown!" Soon, the news came back that at a distance of 500 meters, it failed to penetrate the frontal head armor of the IS-3.

"Okay, let me take a look." The bearded man also went forward to see how it was.

In front of the beard, the armor of the IS-3 was punched, but it did not penetrate, the projectile got stuck in the armor and should have penetrated by half, judging by the thickness.

"Four hundred meters, continue!" The bearded man shouted excitedly.

The 88 gun was pushed forward again by 100 meters, with a long barrel, closer to the IS-3.

"Fire!"

"Boom!"

The long barrel erupted again, and the projectile slammed into IS-3 again, making a sound.

After the smoke cleared, this time the bearded man personally ran up to see the frontal armor of the IS-3.

At 400 meters, it still didn't break through, but the projectile was deeply stuck in the armor, and it seemed that it could be penetrated with more force.

"Three hundred and fifty meters." This time it was only 50 meters advanced, with some caution.

350 meters, hard-core armor-piercing projectile.

After the 88 gun fired, the bearded man immediately went to take a look, but at a distance of 350 meters, the frontal armor of the IS-3 could not block the hard-core armor-piercing shell of the long-barreled 88 gun, and a hole was pierced, and the beard could see through the pierced hole.

Although 350 meters could not block the attack of the 88 guns, the bearded man was also satisfied.

However, he also wanted to see how far he could penetrate the front of the IS-3, so he let the 88 gun retreat 10 meters and shoot at the IS-3 at a distance of 360 meters.

And this cannon just met the requirements of the bearded, and the projectile of the hard-core armor-piercing projectile just penetrated the armor of the IS-3, but it did not penetrate all of it, half of it penetrated, and half of it was stuck in the armor, revealing its head.

"In other words, this tank can block the hard-core armor-piercing shells of the 88 guns at a distance of 360 meters?" The bearded man said happily.

"Yes, frontal armor could block German 88mm long-barreled anti-tank guns at a distance of 360 meters." The testers were also very happy, thinking about how to imitate these tanks, which are very similar to their IS tanks, and it should not be difficult to imitate.

In addition to hard-core armor-piercing bullets, there are also armor-piercing bullets and cap-piercing bullets, which are common armor-piercing bullets in the German army, so they must also be tested.

The armor-piercing projectile does not have much requirements for distance, it mainly relies on the metal jet formed after the explosion to penetrate the armor, and there is no requirement for kinetic energy, but the armor-piercing projectile is easy to be stopped by the gap armor, which is simple, hang some tracks on the front, and simply and effectively defend against the armor-piercing projectile.

The cap-piercing shell is to weld a tough, blunt coat cap on the outside of the head of the armor-piercing bullet to reduce jumping, and it is also the most widely used anti-armor artillery and tank gun shells in World War II.

The cap-piercing projectile needs the kinetic energy given when the gun is fired, and the frontal armor of the tank is quickly hit to penetrate it, and the flat warhead reduces and increases the resistance of the shell's flight, so a soft substance is added to the shell, and it will be bounced off as soon as it touches the tank armor, so that it can be hit on the armor of the tank, which has a good effect on the inclined armor.

Because the cap-piercing shell has a good penetration effect on inclined armor, it is necessary to give it a try.

The IS-3, which had been hit several holes by hard-core armor-piercing shells, was towed away, and a new IS-3 was driven up again for testing with armor-piercing bullets.

The test distance started directly at 500 meters, but at 300 meters, the IS-3 penetrated head-on, which was 60 meters less than the hard-core armor-piercing projectile.

60 meters may not seem like much, but even 1 meter away on the battlefield is enough to decide life and death.

For the frontal protection test, the beard was very satisfied, as for the defense of the turret, it did not penetrate after 100 shots, so the wise choice of the beard was not tested.

As for the sides and back, the bearded man did not let the test either, and on the battlefield, the tank only had to face the enemy head-on and block the shells fired from the front.

The key to a tank is protection, which can block enemy fire. The second is firepower, capable of delivering blows to the enemy.

The IS-3 is equipped with a 122mm gun, which is very powerful, but, but, ah, because the space is too narrow, it has to be used in separate installations, which also leads to its firing speed of only 1~2 rounds per minute, which is super cheating.

However, the bearded man clearly ignored the ultra-slow reloading of the IS-3, and in his opinion, the protection of the tank was the most important. It seems that it was scared of the German tanks, and now he is most concerned about the protection capabilities of the tanks. On the battlefield, the tank only needs to face the enemy head-on and block the shells fired from the front. (To be continued.) )
