The M79 is a grenade launcher that appears in Medal of Honor: Warfighter. The M79 grenade launcher is a single-shot, shoulder-fired, break-action grenade launcher and first appeared during the Vietnam War. While largely replaced by the M203, the M79 has remained in service in many units worldwide in niche roles.
The M79 Grenade launcher is the default class ability for the Assaulter when an M320 is not equipped to the player's weapon. The M79 is best used to flush out enemies from behind cover or from elevated positsions. The player is given 2 rounds of ammo and is not replenishable.
