text: Heavier multi-shot grenade launchers like the ARWEN 37 are used as tear gas and smoke projectors in riot control, while military launchers like the Milkor MGL are used to provide heavy sustained firepower to infantry; most such devices, dating back to the Manville machine-projector, use a revolver-style cylinder, though a handful of pump-action weapons built like oversized shotguns, such as the China Lake grenade launcher and GM-94, also exist.
