From Halopedia, the Halo wiki
The M5100 40mm low-trajectory missile (LTM) is a kind of missile explosive ordnance employed by the United Nations Space Command. It is the primary munition used in the M80 Multiple Launch Rocket System and its derivatives, replacing the 65mm Argent V missiles used in the M79 MLRS. However, it is not the only munition used by the launcher.
