Marine expeditionary unit


A Marine Expeditionary Unit (MEU, pronounced "Mew"), formerly called Marine Amphibious Unit (MAU), is the smallest Marine air-ground task force (MAGTF) in the United States Fleet Marine Force. Each MEU is an expeditionary quick reaction force, deployed and ready for immediate response to any crisis, whether it be natural disaster or combat missions.

A Marine Expeditionary Unit is normally composed of: a reinforced Marine infantry battalion (designated as a Battalion Landing Team) as the ground combat element, a composite medium tiltrotor squadron forms the aviation combat element, a combat logistics battalion provides the logistics combat element, and a company-size command element serves as the MEU headquarters group. Troop strength is about 2,200 and usually commanded by a colonel, and is deployed from amphibious assault ships. Currently, a Marine expeditionary unit embarks Marines and equipment onto the amphibious warfare ships of an Expeditionary Strike Group (ESG) which also includes escort ships and submarines to protect them from air, surface, and submarine threats. For further protection and strong air support, such an ESG is often deployed along with one or more carrier battle groups.

The MEU is unique in that its air and ground combat elements are combined with a logistics combat element under one commander; other services do not unite the command of air and ground forces until much higher command levels.

When the United States Army integrates with Air Force assets, it typically is at the theater or corps level, with a general commanding, while at the division level it will integrate with Army aviation, which can be organized as organic at the battalion level.
