Type 72Z

The Type 72Z is an Iranian-developed, extremely modernized version of the Soviet T-55 tank. The upgrades to the T-55 which creates a Type 72Z is the replacement of the older 100mm D-10 main gun with the 105mm M68, to allow for a longer service life, high efficiency, and simple replacement process without needing to remove the tank's entire turret, as well as an improved stabilization system for the main gun. The Type 72Z also features an improved power supply, engine, and unified internal systems into a so-called "power pack", designed to allow for a shorter repair time.
