M79 Grenade Launcher

The M79 grenade launcher is a single-shot, shoulder-fired, break-action grenade launcher that fires a 40×46mm grenade, which uses what the US Army calls the High-Low Propulsion System to keep recoil forces low, and first appeared during the Vietnam War. Because of its distinctive report, it has earned the nicknames of "Thumper", "Thump-Gun", "Bloop Tube", "Big Ed", and "Blooper" among American soldiers as well as "Can Cannon" in reference to the grenade size; Australian units referred to it as the "Wombat Gun". While largely replaced by the M203, the M79 remained in service in many units worldwide in niche roles.

In addition to 40mm grenades, the M79 is capable of firing a rocket-powered grapnel hook (Range 12/24/48).
