Grenade machine gun

The Heckler & Koch 40mm Grenade Machine Gun (GMG) provides unrivalled infantry suppression combining the best characteristics of the heavy machine guns or light mortars usually employed in this role.

Conventional rifle ammunition provides no fragmentation effect and is largely not effective enough against advancing armoured infantry fighting vehicles and battle tanks. On the other hand, mortars have the disadvantage of a relatively low rate of fire.

The GMG combines the advantages of both of these two types of weapons delivering high flexibility and firepower combined with the fragmentation effect of mortar ammunition.

The GMG is usually mounted on WMIK (weapons mount installation kit) Land Rovers but can also be used from ground-based tripods.
