An automatic grenade launcher or grenade machine gun is a grenade launcher firing rounds in quick succession from an ammunition belt or large-capacity magazine. They can be attached to a tripod. Automatic launchers include the Mk 19, Vektor Y3, AGS-17, and the HK GMG, which all fire at a higher velocity than related shoulder-fired grenades. They generally function as large-caliber machine guns with a relatively low rate of fire, used from an emplaced position in a similar way to a heavy machine gun.
The heavy equivalent of the XM29 is the XM307 ACSW automatic grenade launcher that is easily convertible between the 25 mm grenade ammunition and standard .50 BMG cartridges. Both are intended to fire programmable "smart" grenades capable of being set to explode at a certain distance from launch or at a certain height above the ground. This gives the ability to hit targets inside rooms or behind hard cover that would normally not be reachable by small arms fire.

Famous quotes containing the words automatic and/or grenade:
“Predictions of the future are never anything but projections of present automatic processes and procedures, that is, of occurrences that are likely to come to pass if men do not act and if nothing unexpected happens; every action, for better or worse, and every accident necessarily destroys the whole pattern in whose frame the prediction moves and where it finds its evidence.”
—Hannah Arendt (1906–1975)
“Suddenly he found he had pressed the spring of the grenade. He struggled to pull it out of his pocket. It stuck in the narrow pocket. His arm and his cold fingers that clutched the grenade seemed paralyzed. Then a warm joy went through him. He had thrown it.
Anderson was standing up, swaying backwards and forwards. The explosion made the woods quake.”
—John Dos Passos (1896–1970)
