The Fleet Marine Force Combat Operation Insignia (FMFCOI) must be authorized by the Marine Corps unit commander in order to be worn by U.S. Navy sailors such as hospital corpsmen, Religious program specialist, and chaplains assigned to Marine Corps units and Seabees assigned to naval units operating with Marine Corps units.
