m1a3

Latest version of U.S. tank M1 Abrams. Enhanced with such nifty features as NBC and independent thermal imaging as well as a stabilizer for the 120mm smoothbore allow the M1A3 Abrams to fight in all conditions and on the move.

1 battalion of these could have routed the whole fucking Iraqui Army in a few days.(With zero causualties)
