Name	Entered service in	Origin	Notes
T-80[14]	1976	Soviet Union	World's first turbine engine equipped tank. Though the Swedish Stridsvagn 103 that entered service in 1960s used a turbine engine alongside a diesel. However, T-80 in Hilmes's book is very different to a T-80 in real world,[15] and early models of the T-80 offer no big differences compared to T-64A in overall performance. So models prior to the T-80B should be regarded as Second generation intermediate.

• Note to the Pancerni website source: Translation of most important parts of 1st, 2nd, 2.5 and 3rd generation MBTs characteristics: "The first generation MBTs are tanks made immediately after WWII. The second generation MBTs have better sights in comparison to the first generation MBTs. Also second generation MBTs were the first ones to use laser sights and APFSDS rounds. The third generation consists of tanks armed with high caliber and velocity guns like M1A1 Abrams. Third generation tanks also use composite armour as well as armour made out of highly resistant sintered ceramic materials. Third generation tanks also have full stabilization system for the main gun. There tanks between second and third generations, like Soviet T-72 which has powerful gun which would classify it as a third generation MBT but at the same time the stabilization system is much too primitive for it to a third generation MBT. It also lacks engine power to be a third generation MBT and has ammunition with less quality."
