No physical evidence for battle of stalingrad.
It's unknown that, during battle of Berlin, soviet's charged into flamethrowers and btfoed themselves.
Soviet friendly fire was entire war. Capitalism is literally retards.
Soviet human waves were events such as seelow heights where they just btfoed themselves with artillery. The penal units never existed. However instead they just btfoed themselves anyway.
Nazis did not use mines and they didn't use much of anything in general. However they didn't need to. Soviets had no problem with firing artillery at themselves.
