The MK19 Mod3 40mm Grenade Machine Gun was first developed by the Navy in the early 1960's. TACOM-ARDEC has since suggested modifications to this system which has enabled the Army to deploy the MK19 in the harsh environments encountered during world-wide operations and has therefore enhanced its performance. The MK19 firing rate is over 350 grenades per minute and it is effective to ranges of over 2200 meters. The system was deployed in Southwest Asia during Operation Desert Storm and devastated enemy infantry.
