The T-72 is a Soviet-designed main battle tank that entered production in 1970.It replaced the T-54/55 series as the workhorse of Soviet tank forces (while the T-64 and T-80 served as the Soviet high-technology tanks). In front-line Russian service T-72 are being replaced by T-90, a modernized version of the T-72. While in the Ukraine T-72s are being replaced by the T-80 and T-84 MBTs.While the T-64 was deployed only in forward-deployed Soviet units, the T-72 was deployed within the USSR and exported to non-Soviet Warsaw Pact armies and several other countries. In addition to production in the USSR it has been built under license in Czechoslovakia, India, Poland and former Yugoslavia.The T-72 medium tank is similar in general appearance to the T-64.The gunner's IR searchlight is mounted to the right of the main gun. The 12.7-mm NSV anti-aircraft machine gun has a rotating mount, and there is no provision for firing it from within the tank. There are normally only a few small stowage boxes on the outside of the turret, and a single short snorkel is stowed on the left side of the turret.
