I was watching this T-90 vs. Abrams video today http://www.youtube.com/watch?v=9L0SPYJNhII and thought to myself this is rubbish. The Russians seem to be impressed that their tank can jump airbourne off prepared ramps and run about quickly in a field, but so what. How does a T-90 compare to the latest Abrams MBT? Can the T-90's gun penetrate the Chobham/DU armour of the Abrams? Can the T-90's armour stop the Abram's 120 gun? Has any Russian T-64/T-72 derived tank ever defeated even the earliest Abrams?
