For a time, countless shells of various calibers flew from all directions and smashed on the body of the "KV-1" tank, ping-pong, and there were piercing whistling and explosions everywhere, but the "KV-1" tank was indestructible, Sun Hui turned the muzzle and opened fire again, destroying a "No. 3" tank.

What Sun Hui is doing now is the standard "free fire", that is, as long as it is a target that can be seen and is close, no matter what tank, anti-tank gun or armored vehicle, he will do it all. After a while, the German array burst into flames and explosions.

The German armored vehicles and motorcycles dodged to the side, and the German tanks attacked the "KV-1" tank while moving, attracting the fire of the "KV-1" tank, and some anti-tank guns also began to shoot, the Germans' shelling was very accurate, but although the shells fired by the German tanks hit the "KV-1" tank like a torrential rain, they did not cause any damage to the "KV-1" tank, Sun Hui's shooting was not even interfered with, and the girls' courage gradually increased. Every time Sun Hui destroyed a German tank, they let out a cheer, and even Du Lili, who had always been afraid of battle, dared to drive the tank and take the initiative to rush forward to ram the German light tank, and crushed two German anti-tank guns one after another.

Seeing the garbage performance of the German anti-tank guns, Sun Hui couldn't help but secretly rejoice.

At this time, the main anti-tank equipment of the German army was a light towed artillery, that is, the 35/36 37 mm anti-tank gun, which was equipped in a special anti-tank company, and each infantry regiment was under the jurisdiction of an anti-tank company. Confidence in this artillery was established during the Polish campaign in August-September '39, however, due to the extremely limited armored armament of the Polish army, this weapon did not undergo any severe tests in the German-Polish war. The real test came 1 year later, when this artillery met in France with British tanks with heavy armor protection.

The advantages of the 35/36 anti-tank gun were mainly due to its maneuverability. It was a light artillery with a total combat weight of only 432 kg, the gun was run on two large wheels equipped with pneumatic tires, and it was not difficult to operate the gun by relying on the manpower of the gunner squad. It can be towed by a car or some similar light vehicle, and it is also very easy to put it on a truck case or a railroad flatbed. It can fire armor-piercing shells as well as grenades, so it can perform a variety of missions, not just a single task against armored vehicles. Its weakness is its rather poor armor-piercing ability. At '34 it was considered satisfactory in armor-piercing, but by '39 it was far behind. However, this flaw was overshadowed by the old tanks it faced in the Spanish Civil War and the Polish War. In addition, the sloping deck adopted on the tank easily nullified the small projectile of the 37-mm anti-tank gun.

During the German lightning attack on France, the Type 35/36 anti-tank guns were sent to France along with the German armored units as the main firepower pillar for the defense of enemy tanks. However, this artillery did not meet the high hopes placed on it by the Germans. During this time, a large number of German transport vehicles and their equipment were seriously damaged by the British army, and tracer bullets ignited a sea of fire. So much so that when the British Matilda tanks were machine-gun fire at a distance of 600-800 yards (548-731 m), the German anti-tank gunners abandoned the guns and fled. Some German soldiers surrendered with their hands raised, others pretended to be dead and lay on the ground! None of the anti-tank weapons they were equipped with could penetrate the armor of the British Matilda-1 and Matilda-2 tanks, not even the field guns from which they fired grenades. Only a few of the British tanks had their tracks broken, and a few tanks caught fire after being hit by German tracer shells, mainly in the engine room of the "Matilda-1" tank. One of the British tanks "Matilda" was directly hit by 1 German 37-mm anti-tank gun with 14 shells, but it did not cause a lethal effect, the only effect was to penetrate a little armor!

The French campaign had proved that the 37-mm anti-tank gun was no longer a good weapon, so the Germans immediately began to implement the next development plan. The design of the plan was ready at the time, but it was not yet ready for the transition to production. In the meantime, the 37-mm gun has also been improved, and a better anti-tank shell has been produced for it, which has a higher muzzle velocity and 30% higher armor-piercing power than standard shells. Until the advent of new types of artillery, such a transitional approach is also justified. For the Germans, it is not known whether it was lucky or unfortunate, from the second half of 40 to the first half of 41 was a relatively calm period in terms of armored operations, therefore, the shortcomings in the performance of the 37-mm anti-tank guns in their hands were temporarily covered up in the past.

In the second half of the 40s, a new type of first anti-tank gun appeared, which was a scaled up version of the 37-mm anti-tank gun, and it was also listed as a main gun on German tanks. Significant savings were made possible in production due to the use of the same caliber for tank guns and anti-tank guns, and since 40 years later, a universal ammunition has been used on both guns. This new type of artillery is the Type 38 anti-tank gun, which will become the main force of German anti-tank weapons in wartime. In order to reduce the recoil acting on the gun, it has a high-efficiency muzzle brake, which also creates conditions for the use of lightweight anti-recoil devices, so that the weight of the whole gun is reduced. It was covered with hardened rubber tires to simplify maintenance and save on the amount of rubber that was in short supply at the time. When marching, the impact from the ground is absorbed by a resilient and robust torsion bar cushion. These two features of this gun, the muzzle brake and the torsion bar buffer, were so successful that they were used in every anti-tank gun produced in Germany later. Despite all the clever new designs, the armor-piercing power of this gun was slightly better than the outdated Type 35/36 37mm anti-tank guns.

And in the early days of the Soviet-German war, the disadvantages of the insufficient power of German anti-tank guns can be said to have reached their peak.
