5th Marine Expeditionary Unit

The Fifth Marine Expeditionary Unit (5MEU) is attached to the 3rd Marine Expeditionary Force, as part of the Fifth Fleet.

The Marine Expeditionary Unit is a Marine Air Space Ground Task Force (MASGTF) with a strength of about 2,200 personnel. The MEU consists of a command element, an infantry battalion, a medium armoured battalion, an artillery company, a tactical fighter squadron with air-support capabilities, an air transport squadron and a combat logistics battalion.

An MEU would typically be commanded by a full Colonel, supported by a Lieutenant Colonel and a Command Sergeant Major - to form the MEU Command Staff. Each of the Battalions would typically have their own unit commander - often a Lieutenant Colonel, but sometimes a Major. Each of the squadrons would have a unit commander, normally a Major or better.
