*The Marines do not have a unit equivalent to the Army’s Corps. The Marine Expeditionary Force could command multiple Marine divisions, but during Operation Phantom Fury it only contained the 1st Marine Division. In reality, the MEF was part of theMulti-National Corps—Iraq.
Note: In the Army, the term ‘Regiment’ is used for historical purposes only, i.e. 503rd Infantry Regiment or the 4th Cavalry Regiment.
