Four M134D Gatling-style machine guns were transferred through U.S. counterterrorism assistance to the Philippine Marine Corps in June 2017; the Marine commandant said troops in Marawi were the priority recipients, while available sources document supply and intended operational priority rather than specific firing incidents.

The best-known Western example is the M2 Browning family, a belt-fed, recoil-operated heavy machine gun used from ground mounts, vehicles, boats, and aircraft mounts. In the Battle of Marawi, Philippine reporting documents a caliber 50 heavy machine gun used by government forces for suppressive fire during urban fighting, while Nigerian reporting from the Boko Haram Insurgency documents a .50 inch Browning machine gun recovered from Boko Haram terrorists at Gombi in 2015.

In the Yemen Civil War, Amnesty International reported Belgian Minimis deployed by The Giants Brigades, tying the weapon to UAE-backed coalition-aligned ground forces around the Hodeidah offensive.
