Comparing: AMX 30 1er prototype vs. E 50

Developed as part of a competitive search for a unified European tank. The vehicle turned out to have maneuverability, engine power, and effective anti-tank engagement distance superior to all other vehicles except the Leopard 1. The armor of the vehicle was quite thin, but it was decided that technological advances in anti-tank shells had essentially rendered armor obsolete: survivability would depend on mobility and firepower.

In 1945 the E 50 was conceived as a standard medium tank of the Panzerwaffe to replace the Panther and Panther II. It existed only in blueprints.
