Armour T-72 MBT
“The T-72, which entered production in 1971, was first seen in public in 1977. The T-72, introduced in the early 1970s, is not a further development of the T-64, but rather a parallel design chosen as a high-production tank complementing the T-64. The T-72 retains the low silhouette of the T-54/55/62 series, featuring a conventional layout with integrated fuel cells and stowage containers which give a streamlined appearance to the fenders. 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.” 
“Laser rangefinders appear in T-72 tanks since 1978, earlier examples were equipped with parallax optical rangefinders, which could not be used for distances under 1000 meters. Some export versions of T-72 lacked the laser rangefinder until 1985 or only the squadron and platoon commander tanks (version K) received them. After 1985, all newly made T-72 came with reactive armour as standard, more powerful 840bhp V-84 engine and an upgraded design main gun, which can fire guided anti-tank missiles from the barrel. With these developments the T-72 eventually became almost as powerful as the more expensive T-80 tank, but few of these late variants reached the economically ailing WARPAC allies and foreign customers before the Soviet bloc fell apart in 1990.
Since 2000, export vehicles have been offered with thermal imaging night-vision gear of French manufacture as well (though it may be more likely that they might simply use the locally manufactured 'Buran-Catherine' system, which incorporates a French thermal imager).
