Marine Expeditionary Force Law and Legal Definition

A Marine Expeditionary Force (MEF) comprises a MEF Headquarters Group, Marine Division, Marine Air Wing and Marine Logistics Group. For example, the I Marine Expeditionary Force (I MEF) is composed of a headquarters element, the 1st Marine Division, 3rd Marine Aircraft Wing and the 1st Marine Logistics Group, all based on the West Coast. Two notable deployments of an entire MEF were when I Marine Expeditionary Force deployed in support of Operations Desert Shield and Desert Storm. I MEF ultimately consisted of the 1st and 2nd Marine Divisions as well as considerable Marine air and support units. I MEF also deployed to Somalia in December 1992 for the humanitarian relief effort there as well as deploying to Kuwait beginning in 2002 and taking part in the 2003 Invasion of Iraq.
