The Vroombar is the tank we don't deserve

Einzelganger7: By reading the title I just want to say that the "Brummbär" is a nickname given by the Allies and "Stupa" by the German, the actual name is Sturmpanzer IV so the Sturmtiger is a completely different vehicle. The first had a 150mm cannon and the chassis of a Panzer IV while the second had a 380mm raketenwerfer (rocket thrower) and as the name suggests, it has the chassis of a Tiger I.
