The 60mm mortar cartridges are designed for use with the M224 lightweight company mortar system (LWCMS) in all light infantry battalions including Airborne, Air Assault and Ranger.

The M720 60mm High Explosive (HE) cartridge with M734 Multi-Option Fuze is used against personnel and materiel providing both fragmentation and blast effect. It consists of a multi-option fuze, tail assembly, and projectile body with a TNT or composition B explosive fill.

The M720A1 HE cartridge with M734A1 Multi-Option Fuze incorporates several new design features, which significantly decreases its sensitivity to unplanned stimuli (enhanced insensitive performance). A new insensitive main charge called PAX-21 has replaced the composition B explosive. Additional changes have been made to the fuze adaptor, packaging and fuze explosive charge. Lethality is maintained by using a high fragmentation steel (HF-1) shell body. The M720A1 also incorporates the highly reliable and countermeasure resistant M734A1 Multi-option fuze.

The M721 illuminating cartridge provides visible light illuminating capability at the same effective range as the companion High Explosive (HE) cartridges. The M721 is ballistically similar to the M720A1 HE Cartridge, allowing a gun to illuminate and fire on the same target without adjustments. The M721, and infrared illuminant, M767 rounds are identical except for the composition of the illuminant.

The M722 WP smoke cartridge provides a smoke cloud for spotting or marking a target area. It is assembled with the M745 point detonating fuze which functions on impact. The cartridge has in integral burster charge, white phosphorus filler, a thin wall shell, fin assembly, a four increment M204 propelling charge, and an ignition cartridge.

The M767 provides infrared illumination which greatly enhances the effectiveness of night vision devices at the same effective range as the companion High Explosive (HE) cartridges. The M726 is ballistically similar to the M720A1 HE Cartridge, allowing a gun to illuminate and fire on the same target without adjustments. The M726, and visible light illuminant, M761 rounds are identical except for the composition of the illuminant.

The M768 High Explosive/Point Detonating (HE/PD) cartridge uses the new M783 dual safety, point detonating/delay fuze. It will also use PAX-21 insensitive explosive fill, and a new fuze adapter and packaging that enables the round to meet most insensitive munitions requirements. Lethality is maintained by using a high-fragmentation, steel (HF-1) shell body.

The M888 round is used against personnel and materiel providing both fragmentation and blast effect. It uses the M935 point detonating fuze, fin assembly, and a projectile body with a TNT explosive fill.
