MBT-70 joint venture between the US and Germany. 3 crew, all in the turret. 1400bhp diesel engine. American version had a longer version of the 152mm Gun/Missile launcher from the M551 (a weapon that doesn't really work). German version used the Rhienmetal 120mm smoothbore gun simmilar to the one on the Leopard 2 and the M1A1.
