Back to topic - americans once builded gun for 152mm AT rockets,and used it on light tank M551 Sheridan.They planned to use it on MBT 70 tank,but abadonned that project.
Could somebody built something like MBT 70 with better AT rockets ? And would be such tank better then those with 130/140mm guns ?
