What is M1a3?
1.
A tank that doesn't really exist. That guy is sure uneducated, the latest version of the Abrams series is the M1A2 SEP. The first version of the Abrams had stabilization to fire on the move. the M1A1 incorperated an NBC Overpressure system, not sure what this guy is talking about.
The M1A3 does not exist.
2.
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)
