This is hair-raising.
Sucks to be the guys who suddenly find out the untermenschen have T-34s and KV-1s and none of the wonderful German guns will penetrate the enemy tanks’ armor.
The Aryan Supermen were obliged to climb onto the back of the Soviet tank, chop through the ventilation grill over the engine with an axe, and then place a hand grenade through this improvised opening to try to disable the engine. Meanwhile, the Red Army infantry were, in theory, being kept too busy by the other Wehrmacht guys on the team to shoot Hans off the back of the tank before he was finished with the axe-and-grenade improvisation.
The Germans also had a gimmick of mines affixed to a plank and then maneuvered in front of the tank with a rope by a guy hiding in a nearby hole in the ground, as another low tech solution to the problem.
Relying on kludges is bad enough under peacetime conditions. This stuff could get you killed.
