Marine Expeditionary Force

A Marine Expeditionary Force, (abbreviated MEF) is a large organization of the UNSC Marine Corps that contains at least one division-sized unit of Marines.

An MEF is likely the same or similar to the Expeditionary Forces of the 20th century, one example of which was the 1st Marine Expeditionary Force of the US Marine Corps, who were separated into the 1st Marine Division, the 3rd Marine Aircraft Wing and the 1st Marine Logistics Group. Overall, an MEF is designed to be self-sustaining, already covering important requirements such as a large number of troops, an Air defense, and spare men required for maintenance, treating wounded and delivering supplies.
