Same reason why Israel keeps a bunch of really old tanks around. China used to expect an apocalyptic ground war with Russia, and the older tanks would work as mobile artillery for non-frontline troops.And why is there still 59s in service with the PLA? Shouldn't these round-turret old dudes belong to museums or the Middle East?
Sonic "weapons" only displayed and installed for parades.Nice picture but what are those four boxes on the right of the commander with the machinegun?
Perhaps a kind of aps? And what about the original laser self protection system behind the gunner?
