It was replaced by the Mk 19 grenade launcher in service with the United States Armed Forces. DesignThis weapon is a manually-operated, belt-fed. The use of a split breech mechanism allowed the weapon to be light and simple. Test resultsThe Mark 18 was used primarily on small boats or in fixed positions such as bunkers; their primary users were the so-called "river rats" and the SEALs. They could be mounted on M2HB, M60, M1919 tripods, or pintle mounts, but could not be fired without such a mount.{{Citation needed|date=December 2018}} See also
