The Mk 19 (Mark 19) is an air-cooled, belt-fed, blowback-operated 40mm automatic grenade launcher primary deployed by the U.S. Marine Corps, U.S. Army, and Special Operations forces. First introduced during the Vietnam War for riverine craft, the modern variant—the Mk 19 Mod 3—serves as a devastating crew-served heavy support weapon for infantry units and vehicle platforms.
Mounting Options: Can be stationary on an M3 tripod or mounted atop tactical vehicles including the Joint Light Tactical Vehicle (JLTV), HMMWV, Amphibious Combat Vehicle (ACV), and riverine patrol craft.
Fire Support Role: Provides suppressive fires against enemy infantry in defilade, light armored vehicles, fortified bunkers, and urban structures.
