The M830 is an American high explosive anti-tank (HEAT) round meant primarily for the 120 mm M256 main gun of the M1A1 and M1A2 Abrams. Aside from the double safety, propellant containment bag and M764 fuze, it is identical to the German DM12A1. The cartridge weighs approximately 53.4 lb (24.2 kg). The round was praised for its performance during the 1991 Gulf War. It is no longer manufactured and has been replaced by the M830A1.
