some light tanks. The ammunition used in the M242 may also be used in a variety of weapons such as the GAU-12 Equalizer, the French Giat M811, or the Swiss Oerlikon KBA weapon system. It has the capability to fire U.S. manufactured ammunition as well as the NATO equivalents thereof. Primarily though, it fires six types of rounds: the M791, M792, M793, M910, MK210, and M919. M791 Armor-piercing discarding sabot with Tracer The APDS-T penetrates lightly armored vehicles, self-propelled artillery, and aerial targets such as helicopters and various slow-moving, fixed-wing aircraft. M792 High Explosive Incendiary with Tracer and Self Destruct The HEI-T can destroy unarmored vehicles and helicopters and suppress anti-tank missile positions and enemy squads out to a maximum effective range of 2,200 meters. M793 Target Practice with Tracer The TP-T cartridge is a fixed-type, percussion-primed training round that matches the High Explosive Incendiary with Tracer (HEI-T M792) round ballistically. The TP-T's tracer is visible out to 2,000 meters, however, the round has a maximum effective range (accuracy-limited) of 1,600 meters. M910 Target Practice Discarding Sabot with Tracer The TPDS-T replicates the flight pattern of the M791 Armor Piercing Discarding Sabot with Tracer (APDS-T) round. The TPDS-T allows units to realistically practice sabot engagements. MK210 High Explosive Incendiary with Tracer Used by the U. S. Navy in their Mk38 naval weapon system. M919 Armor-Piercing, Fin-Stabilized Discarding Sabot With Tracer. The APFSDS-T round penetrates light armored vehicles, self-propelled artillery, and aerial targets, which includes helicopters and slow-moving fixed-wing aircraft. The dart is made of depleted uranium. Variants The M242 is currently in use by the United States Army, Navy, Marine Corps, and Coast Guard, the New Zealand Army, Royal New Zealand Navy, the Norwegian Army, the Spanish Army, the Sri Lanka Navy, the Swiss Army, the Canadian Army, the Australian Army and the Royal Australian Navy, the Israeli Navy, Philippine Navy and Philippine Army, the Singapore Army and Republic of Singapore Navy as well as several others. The wide usage results in several variations and modifications on the standard M242 weapon system. Ground vehicles The M242 is standard equipment on the U. S. Army M2 and M3 Bradley fighting vehicles; it is also in use on the LAV-25. Before the project was cancelled, the Mk44 Bushmaster II 30 mm chain gun (a successor to the M242) was used on the Marine Corps' Expeditionary Fighting Vehicle (EFV). The M242 is also
