Although the details depend on the model, the M1 characteristically comes with highly effective targeting optics, electronic control systems and software, and fire suppression system. Against the Iraqi Army, we could see and hit them at night, in rain or sandstorms, and at longer range. Personally, I am all for the Iraqis adopting Russian tanks and equipment. That will make it easier if we or an ally has to settle their hash again in the coming years.
Oh yeah the M1A1’s during Desert Storm could engage and destroy the Iraqi tanks at ranges well outside their detection range. In fact @ 73 Easting, some of the Iraqi commanders thought they were being hit with airstrikes.
