There are three types of T-80 in the mid 1990s – T-80B, T-80U and T-80UD.
The T-80 were only in the western regions against NATO. In 1990. There were 3735 T-80B, 617 T-80BV, 410 T-80U and 500 T-80UD. Further production into the mid 1990s would have been T-80UD.
T-80B had gas turbine engine which had high fuel consumption and higher running costs as the engines were more expensive to run and maintain. The T-80B and T-80U cannot create engine smoke due to the higher engine temperatures, but have smoke grenade launchers.
The T-80B is the fastest at 70 kph and had the best tank fire control of Soviets tanks, including fire on the move capability.
70 kph is 9.7 on road and 48 kph cross country or 6.6 cross country or 10/7 in game terms, which is close to game stats.
T-80B protection is as the T-64B, so
Front 11, -1 vs HEAT

Rear 6
T-80BV adds Kontakt-1 ERA which is -2 against HEAT weapons only.
T-80U protection improves. It has the Kontakt-5 ERA which adds 120mm against APFSDS and 500mm against HEAT. Frontal armour goes up to around 780mm APFSDS and 1320mm against HEAT. So base armour is 660mm APFSDS and 820mm HEAT which seems a little high. Fourth edition these small differences go away.
Front 12, -1 vs HEAT (ERA adds -1 APFSDS, -2 vs HEAT). Actually these would be positive modifiers?

Fuel is 1840 litres with the option of adding three 200 L fuel drums on the deck. 1840 Litres gives 500 km road range which gives the fuel consumption of 37 in game terms.
T-80UD goes back to a diesel engine which has the multi-fuel option. Top speed drops to 65 kph road and 45 kph cross country or 9/6 in game terms. Internal fuel drops to 1770 L. Range increases to 580 km, so fuel consumption is 31.
Coaxial 7.62mm OPPK has 1250 rounds or 5 belts.
The commanders hatch NSV has 500 rounds on the T-80B and 450 rounds on the T-80U series.
See T-64 for the 125mm rounds. The only differences are all versions could launch anti-tank missiles – at the start of the war each tank would have 4 missiles.
T-80B had 38 rounds with 28 in the autoloader.
T-80U series had 45 rounds, also with 28 in the autoloader.
The T-80B could launch the 9M112 Kobra [AT-8 Songster], range is 100-4000 meters or 10-400 hexes. Penetration is 600mm or 12.
T-80U and T-80UD had the 9M119 Svir [AT-11 Sniper], range is 5000 meters or 500 hexes, penetration is 700mm which is 12.
