The third generation is in Western parlance determined by the usage of thermal imagers, digital fire-control systems and special (composite) armour (Soviet doctrine, however, de-emphasizes thermal vision and electronic fire control, preferring large-caliber gun and engines of high power).

The second generation was equipped with NBC protection (only sometimes), night-vision devices, a stabilized main gun and at least a mechanical fire-control system.

The first generation of main battle tanks was based on or influenced by designs of World War II, most notably the Soviet T-34. In 1973, Rolf Hilmes saw three tank generations and three "intermediate generations", which consisted mainly of upgraded vehicles.
