A very important element of infantry training for the development of psychological stability of the infantryman.
It was only from the third time that I was able to fully concentrate on throwing an anti-tank grenade in time and accurately after passing over me exactly such a tank.
We had anti-tank cumulative grenades of the RCG-3EM type. The weight of such a grenade is 1.1 kg., after the throw, a small parachute opens so that the grenade hits the tank's armor with the butt end.
We threw training grenades into tank models virtually daily from different positions. A very difficult element of learning.
