The M791 APDS-T penetrates lightly armored vehicles, self-propelled artillery, and aerial targets such as helicopters and slow-moving, fixed-wing aircraft. It is a fixed-type, percussion, primed round. It consists of a sabot-encapsulated projectile body crimped to a steel cartridge case. The projectile body consists of a solid tungsten alloy penetrator, pressed-on aluminum windscreen, pressed-in tracer pellets, molded discarding-type nylon sabot, staked aluminum base, and welded or pressed-on nylon nose-cap. The projectile sabot and nose-cap are black with white markings.
The M792 HEI-T can destroy unarmored vehicles and helicopters and suppress anti-tank guided missile (ATGM) positions and enemy squads beyond coax range. It is a fixed-type, percussion-primed round. The one-piece projectile body contains HEI and is crimped onto a steel cartridge case. The hollowed steel projectile houses an M758 mechanical fuze, 32 grams of an HEI mix, and a pressed-in tracer. The projectile is yellow with a red band, black markings, and a gold tip.
Direct Impact: striking the target crushes the projectile's probe cap. This pushes the probe rearward, which thrusts the firing pin into the detonator, which detonates the HEI mixture.
Grazing Impact: due to spin decay (loss of forward velocity), the projectile strikes the target with insufficient force. Spin decay triggers the setback spring to overcome centrifugal force, pushes the body assembly forward, and thrusts the detonator into the firing pin.
Self-Destruct: if it does not hit a target, the projectile self-destructs at 3,000 meters. However, head and tail winds, depending on their severity, can reduce the distance at which the round self-destructs.
The M919 APFSDS-T round penetrates lightly armored vehicles, self-propelled artillery, and aerial targets, which includes helicopters and slow-moving fixed-wing aircraft. It is a fixed-type, percussion primed round that consists of a sabot-encapsulated projectile crimped into a steel cartridge case. The projectile is made of slate gray, corrosion-protected, depleted uranium. This round has greater effective range, penetration capabilities, and tracer burn time than the M791 APDS-T.
