YaATW2KT: The Second Mexican-American War

[RN7]

Although U.S. Abram's were been fitted with DU armour from 1988 I would not think all of them had DU armour by the Twilight War. Certainly baseline M1's with 105mm guns would not have had DU armour, and the M1A1's of national guard units like the 49th Armored Division would be among the last to be fitted with DU armour. So U.S. tanks in the southwest would in general not have the same armour protection as those on the front lines in Europe.
