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.
History of the tank
France started studying caterpillar continuous tracks from January 1915, and actual tests started in May 1915, two months earlier than the "Little Willie" experiments. At the Souain experiment, France tested an armoured tracked tank prototype, the same month "Little Willie" was completed.Ultimately however, the British were the first to put tanks on the battlefield, at the battle of the Somme in September 1916.
