Nazi Machines Of War Panzer Viii Maus

By far the biggest battlefield monster to have ever been built, the 188-ton Maus dwarfed any Allied super-heavy tank. It was also over 10m long, with 220mm thick steel armour, and armed with a colossal 128mm KWK 44 L/55 gun. Developed by Porsche, only one was completed and another partially assembled before the Soviets invaded Germany.
