 The Mark 19 Automatic Grenade Launcher, first fielded by the Americans in 1966, and still widely used today, weighs 62.5 kg, when attached to its tripod, and loaded with a box of ammunition.The popular Mark 19 is capable of indirect fire to 2,200 metres, an indirect fire role traditionally reserved for mortars.Even though the round carries less explosive than a 60mm mortar shell, this is thought to be counterbalanced by its much higher volume of fire.
