capabilities. &lt;ref name="urlM830/M830A1"&gt;&lt;/ref&gt; This round is meant for the 120 mm M256 main gun of the M1A1 and M1A2 Abrams. The M830 HEAT-MP-T, 120-mm cartridge is a direct translation of the German DM12A1 round with the exception that a United States design fuze system and explosive (Composition A3, Type 11) is used. The propellant system utilizes a metal cartridge case base with a rubber obturator at the stub case mouth, M123A1 Primer, and a combustible wall which encapsulates stick propellant within six containment devices to prevent spillage should breakage or separation occur. The cartridge is black with yellow markings, weighs approximately 53.4 lb (24.2 kg), and has a length of 38.6 inches (981 cm). The round was praised for its performance during the 1991 Gulf War. It is no longer manufactured and has been replaced by the M830A1.
