The main gun on the American M1A1 Abrams Main Battle Tank is a German-made Rheinmetall 120-mm smoothbore gun, capable of firing High-Explosive Anti-Tank (HEAT) rounds, and Armor-Piercing, Fin-stabilized, Discarding Sabot (APFSDS) rounds, either of which will provide an indiscriminate screaming hot death to any of the foes of America with precision accuracy.
He was one of Patton's tankers and one heckuva military hero!
