What components comprise a U.S. Marine Expeditionary Force (MEF)?

• A. Command Element, Marine Division, Marine Aircraft Wing, and Marine Logistics Group
• B. Headquarters USMC (HQMC), Operating Forces, Marine Corps Reserve (MARFORRES), Supporting Establishments
• C. Command Element, Navy Fleet, Aviation Wing, and Logistics Group
• D. Command Element, Marine Division, Marine Aviation Wing, and Marine Logistics Squadron

Answer: (A)

A Marine Expeditionary Force is a MAGTF built around four integrated elements: a Command Element that provides leadership, planning, and command and control; the Ground Combat Element is the Marine Division, the main land warfare force; the Aviation Combat Element is the Marine Aircraft Wing, delivering air power, including attack, transport, and air support; and the Logistics Combat Element is the Marine Logistics Group, responsible for sustainment, maintenance, supply, and health services. This combination creates a self-sufficient, rapidly deployable force capable of conducting joint operations across land, air, and sea support.
