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.
Conqueror (tank)
The variants of the Conqueror tank and developments directly related to its development are:In the United Kingdom, Conqueror tanks are displayed at The Tank Museum, Bovington, and the Land Warfare Hall of the Imperial War Museum Duxford. Other tanks are in the collections of the Musée des Blindés in France, the Royal Museum of the Army in Brussels and the Kubinka Tank Museum, Russia. One is privately owned in the United States as part of the Littlefield Collection and another is in use as a gate guardian outside the Royal Tank Regiment Officers' Mess, which was restored by 2nd Royal Tank Regiment Light Aid Detachment (REME) in 2009, having previously been in a deteriorating state at Castlemartin Ranges (where it had previously been the guardian "Romulus" before being replaced by a German Leopard MBT).
