The 40×46mm Low-Velocity grenades are used with handheld grenade launchers, such as the M203, the M320 or the M32 Multiple Grenade Launcher. The types of grenades include, among others, high explosive, illuminating, smoke, non-lethal and target practice rounds.
The M397A1 cartridge is a high explosive round designed to inflict personnel casualties using air burst effect. This cartridge is a fixed round of ammunition consisting of a one-piece steel projectile body with a metal rotating band and a cartridge case assembly containing the propelling charge and percussion primer.
The M433 cartridge is a dual purpose impact type round which is designed to penetrate at least two inches (50.8 millimeters) of steel armor at 0° angle of obliquity and inflict personnel casualties in the target area. The cartridge is a fixed round of ammunition consisting of a one-piece, aluminum projectile body with rotating band, and a cartridge case assembly. The grenade has a small shaped charge that penetrates better than the HE round.
The M441 cartridge is a high explosive round designed to inflict personnel casualties using ground burst effect. The cartridge is a fixed round of ammunition consisting of a projectile body with a rotating band and a cartridge case assembly.
The M576 cartridge is intended for use in counter-insurgency and conventional operations in jungle environments, particularly during periods of poor visibility where personnel targets appear at short distances without warning and are vulnerably exposed only fleetingly. The cartridge is a fixed round of ammunition consisting of a multiple projectile assembly and a cartridge case assembly. Though it is a multipurpose round, the M576 is most effective in thick vegetated areas or for room clearing, aiming the buckshot round at the foot of the target.
The star parachute round is used for illumination and signals and is lighter and more accurate than comparable handheld signal rounds. The cartridge is a fixed round of ammunition consisting of a projectile assembly and a cartridge case assembly.
The M585 cartridge is designed for illumination and signaling with less weight and bulk and greater accuracy than comparable hand-held signals. The cartridge is a fixed round of ammunition consisting of a projectile assembly and a cartridge case assembly.
The M651 is a multipurpose round, although it is most effective for riot control and in military operations on urbanized terrain (MOUT). This chemical round is used to drive the enemy from bunkers or enclosed positions in built-up areas. It produces a white cloud of CS gas on impact. The M651 cartridge is similar in appearance to other 40mm cartridges but has a flat nose. The M651 cartridges are not explosive rounds.
The smoke canopy cartridges are designed for accurately marking the position of a man or unit located beneath moderately thick foliage for aerial observation. The cartridge has the advantage of less weight and bulk and greater accuracy than comparable existing signals. The cartridge is a fixed round of ammunition consisting of a projectile assembly and a cartridge case assembly.
The ground marker cartridges are used for aerial identification and for marking the location of soldiers on the ground, but not for screening. The difference among the models is the color of the smoke. The cartridges consist of a cartridge case, a projectile with pyrotechnic smoke payload, and a pyrotechnic impact fuze.
The M992 infrared illuminant cartridge enhances night visibility while using night vision devices. The cartridge is a fixed round of ammunition consisting of a projectile assembly and a cartridge case assembly.
The M1006 is used to incapacitate personnel without penetrating the person's body. It is used for riot control, policing and peace keeping situations. This round is most effective against individually selected targets (point round). It has a foam rubber nose and a high density plastic body. The cartridge is a fixed round of ammunition consisting of a projectile assembly and a cartridge case assembly.
The M1029 Crowd Dispersal Cartridge (CDC) is used to incapacitate personnel without any penetrations to the individual's body. It is used for riot control, policing, and peace keeping situations. It is a direct fire, low-hazard, non-shrapnel-producing, multiple ball projectile that provides friendly forces the capability to conduct crowd control. The CDC uses non-lethal, blunt trauma to stop, confuse, disorient, and/or temporarily incapacitate personnel and increase standoff distance between friendly forces and the hostile crowd. Primarily designed as an area effect munition, the CDC can be used on individuals. Although it is a non-lethal projectile, fatal injuries are possible at employment distances of less than 10 meters. Beyond 30 meters the kinetic energy dissipates until the rubber balls become ineffective.
