Panzer VIII Maus
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by advancing Soviet military forces.

The Chi-To was a thirty-ton, all-welded tank with a maximum armor thickness of about 75 mm. It was much larger than the Type 97 Chi-Ha, with a longer, wider, tall chassis, supported by seven road wheels. The main armament, a Type 5 75 mm tank gun was housed in a large powered, well-armoured hexagonal gun turret. The main gun's muzzle velocity gave it an armor penetration of 75 millimeters at 1,000 meters. The tank had a Type 97 heavy tank machine gun mounted in the hull and a ball mount on the side of the turret for a second one. Two Type 4 Chi-To tanks are known to be completed prior to the end of the war. Neither of the completed tanks saw combat use.
