In the United States Marine Corps, the command element is the command and control force of a Marine Air-Ground Task Force. It provides C3I for the MAGTF.

Role within the MAGTF

The Command Element, a headquarters unit organized into a MAGTF headquarters group, that exercises command and control over the other elements of the MAGTF. The HQ group consists of communications, intelligence, surveillance, and law enforcement detachments, companies, and battalions, and reconnaissance, and liaison platoons, detachments, and companies.

The size of the CE varies in proportion to the size of the MAGTF. A Marine Expeditionary Force has a MEF Information Group, approximately the size of a regiment. A Marine Expeditionary Brigade holds a battalion-sized MEB Information Group. The various Marine Expeditionary Units command a company-sized MEU Information Group. Generally, MEF postings are permanent, while MEBs and MEUs rotate their GCE, ACE, and LCE twice annually.
