how was the Panzer 8 Maus crap? its secondary gun was a 75MM GUN!!!:o .. look carefully in some pictures of the frontal armor, no penetrating hits.. even from 88mm german and russian guns.. give it 1-2 years for development it wud have turned the tide of the war

It was never completed and was very slow due to it's very heavy weight.

The maus was a megalomaniacs wet dream, nothing more. It was too heavy to be mobile, it was to resource and labour intensive to produce and it was still vulnerable to air attack and heavy artillery bombardment. At turning the tide of the war it would have been as much use as bright pink uniforms for ambushing soldiers.
