The T-90 is the main battle tank of the Russian armed forces. While the T-80 is a better tank in terms of speed, the T-90 cost a 1/3 as much. The T-90 uses a 125mm cannon with an auto-loader, so it can fire faster than an M1A1 abrams tank. However, the gun is less accurate and as a result will be less likely to get a hit.
