| ||For an overview of grenade launcher models in the Fallout series, see grenade launcher.|
U.S. automatic grenade launchers were manufactured in two major variants, accepting 25mm and 40mm grenades, together with a variety of additional equipment, such as an electronic fire control system (though most of these systems have failed in the decades after the war, becoming little more than dead weight).
The auto grenade launcher is a powerful, automatic explosive weapon firing belt-fed 40mm grenades. Delivering a high volume of explosive ordnance at the range, it's difficult to ignore, especially when taking into account the damage bonus from the right perk cards (it does not benefit from Heavy Gunner).
