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.
Battle of Prokhorovka
The battle has been widely described as the largest tank engagement or battle in military history, involving 1,200–1,500 tanks and sometimes up to 2,000, but this is incorrect as the battle did not involve that many tanks. The exaggerated figures originated from erroneous Soviet intelligence estimates of German armour reported during and after the battle, and subsequent postwar accounts that furthered this erroneous narrative. Some of these Soviet estimates reported figures as high as 800 German tanks and assault guns attacking Prokhorovka on 12 July.
