The 120mm M830 High Explosive Anti-Tank-Multi Purpose - Tracer (HEAT-MP-T) is a chemical energy, multi-purpose projectile with an anti-personnel capability. It is largely a technology transfer from the ballistically identical German model DM12A1 except for the M764 fuze, double safety, and propellant containment bag. The round consists of a fin stabilized steel body which is loaded with Composition A3 Type II explosive. The fins are canted and impart spin to the projectile. A copper shaped charge liner and wave shaper are contained within the warhead. The projectile has a steel spike with a nose cap switch and a shoulder switch for full frontal area functioning. An electrically initiated base detonated fuze is located in the rear of the body. The propellant system employs single perforated stick propellant. The approximate cartridge weight is 53.4 pounds.
