A Troop, 2nd Squadron, 14th Cavalry Regiment, 2nd Stryker Brigade Combat Team, 25th Infantry Division of Schofield Barracks, HI conducted a Mk 19 range as part of their month-long exercise at Yakima Training Center, WA.
The Mk 19 grenade launcher (also known as the Mark 19) is an American 40 mm belt-fed automatic grenade launcher that entered U.S. military service during the Cold War, first seeing action during the Vietnam War and remaining in service to the present day.
The Mk 19 is a belt-fed, blowback-operated, air-cooled, crew-served, fully automatic weapon that is designed not to cook off. It fires 40 mm grenades at a cyclic rate of 325 to 375 rounds per minute, giving a practical rate of fire of 60 rounds per minute (rapid) and 40 rounds per minute (sustained). The weapon operates on the blowback principle, which uses the chamber pressure from each fired round to load and re-cock the weapon. The Mk 19 can launch its grenade at a maximum distance of 2,212 meters (7,257 ft), though its effective range to a point target is about 1,500 meters (4,900 ft), since the large rear leaf sight is only graduated to 1,500 meters. The nearest safe distance to launch the grenade is 310 meters in training and 75 meters in combat. Though the Mk 19 has a flash suppressor, it serves only to save the eyesight of its operator; it does not conceal the weapon's position. For night operation, a picatinny rail quadrant sight can be added for thermal and night vision optics. [ Ссылка ]
