The Soviet Army adopted the improved T-80BV in 1985. The hull and turret armor was reinforced using dynamic means to defeat anti-tank munitions. The 125mm gun was improved and provided with the means to accurately fire 'Cobra' guided munitions up to a range of 4000 meters while on the move or stopped. The engine was also improved, which allowed the T- 80BV to retain its excellent riding characteristics despite an increase in the vehicle's weight.
