Third generation NATO tanks; Abrams and Challenger

[Roy]

Third generation NATO tanks, mid-to-late eighties and early nineties. Useful for Cold War what-ifs and 1991 Gulf War.

United States of America - M1 and M1A1 Abrams

United Kingdom - Challenger 1 (Mk.2 ?)

Having the above would complement the US and UK NATO models already available, and provide 3rd Gen. tanks to go up against the Soviet 2nd Gen. T-62, T-64, (and to be released T-72) tanks. Someone will probably ask for the Soviet T-80 3rd Gen. tank, I'd imagine.
