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.
Renault FT
The Renault FT (frequently referred to in post-World War I literature as the FT-17, FT17, or similar) was a French light tank that was among the most revolutionary and influential tank designs in history. The FT was the first production tank to have its armament within a fully rotating turret. The Renault FT's configuration – crew compartment at the front, engine compartment at the back, and main armament in a revolving turret – became and remains the standard tank layout. As such, some historians of armoured warfare have called the Renault FT the world's first modern tank.
