Type 72Z

Not to be confused with the T-72 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 main gun with a 105mm weapons system, 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 and faster mounting and dismounting of the pack.

Battlefield 3
The Type 72Z, never referred to in-game, appears as the first few tanks Jonathan Miller and his comrades face down during the mission Thunder Run. They are operated by either the Islamic Republic of Iran Army or Peoples Liberation and Resistance.
