The MK19 grenade launcher was introduced during the Vietnam war. It can fire 40-millimeter grenades up to 1,500 meters. These can punch through three inches of steel and is best used against dismounted infantry and lightly armored vehicles. The Mk19 is most used on vehicle mounts due to its weight. Though it has low recoil, Mk19 weighs over seventy-seven pounds or about thirty-five kilograms.
