The Fleet Marine Force Warfare Insignia, also known as the Fleet Marine Force badge or FMF pin, are three military badges of the United States Navy which are issued to those U.S. Navy officers and sailors who are trained and qualified to perform duties in support of the United States Marine Corps. There are currently three classes of the Fleet Marine Force pin, being that of enlisted, officer, and chaplain. Enlisted The Fleet Marine Force Enlisted Warfare Specialist Device (FMFEWS) is a qualification insignia of the United States Navy earned by enlisted U.S. Navy sailors assigned to the Fleet Marine Force of the U.S. Marine Corps who have successfully completed the requirements of the Enlisted Fleet Marine Force Warfare Specialist (EFMFWS) Program per OPNAV Instruction 1414.4B.
