Comparing: AMX 30 B vs. Centurion Action X

Developed in 1966. The vehicle had maneuverability, engine power, and effective anti-tank engagement distance superior to all other vehicles except the Leopard 1. Great view range allowed the vehicle’s commander to coordinate the actions of the crew and to maintain situational awareness, greatly increasing the vehicle’s effectiveness. 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. A total of 2,800 vehicles were manufactured.

The Action X turret was planned to be used for later variants of the Centurion tank. One prototype of the turret was mounted on the chassis of the Centurion Mark 7, and another was used for ballistic trials. The vehicles with the Action X turret never entered mass production or saw service.
