This assault gun was nicknamed "Animal Hunter". The weight of the AP shell was 48kg, while HE shell was 41kg. Otto Carius : "The shell cut the right part of the commander's cupola. I was not beheaded because I had bent down to light my cigarette. Suddenly the Russian assault gun appeared and I gave an order to the gunner to open fire. Kramer shot, and a second shell, from another assault gun, hit in the turret. I can not remember which way I left the Tiger. The head phones-the only thing I have from my destroyed Tiger".
