Marine Air-Ground Task Force (MAGTF, pronounced MAG-TAF) is a term used by the United States Marine Corps to describe the principal organization for all missions across the range of military operations. MAGTFs are a balanced air-ground, combined arms task organization of Marine Corps forces under a single commander that is structured to accomplish a specific mission. The MAGTF was formalized by the publishing of Marine Corps Order 3120.3 in December 1963 "The Marine Corps in the National Defense, MCDP 1-0". It stated: A Marine air-ground task force with separate air ground headquarters is normally formed for combat operations and training exercises in which substantial combat forces of both Marine aviation and Marine ground units are included in the task organization of participating Marine forces. Since World War II in many crises the United States Marine Corps has deployed projection forces, with the ability to move ashore with sufficient sustainability for prolonged operations. MAGTFs have long provided the United States with a broad spectrum of response options when U.S. and allied interests have been threatened and in non-combat situations which require critical response. Selective, timely and credible commitment of air-ground units has, on many occasions, helped bring stability to a region and sent signals worldwide that the United States is willing to defend its interests, and is able to do so with a powerful force on short notice. Composition The four core elements of a Marine air–ground task force are: The command element (CE), a headquarters unit organized into a MAGTF (MEU, MEB, MEF) headquarters (HQ) group, that exercises command and control (management and planning for manpower, intelligence, operations and training, and logistics functions) over the other elements of the MAGTF. The HQ group consists of communications, intelligence, surveillance, and law enforcement (i.e., military police) detachments, companies, and battalions, and reconnaissance (Force Reconnaissance), and liaison (ANGLICO) platoons, detachments, and companies. The ground combat element (GCE), composed primarily of infantry units (infantry battalions organized into battalion landing teams, regimental combat teams, and Marine divisions). These organizations contain a headquarters unit that provides command and control (management and planning for manpower, intelligence, operations and training, and logistics functions) as well as scout/sniper, aviation liaison/forward air controller, NBC defense, communications, service (supply, motor transport, weapons maintenance, and dining facility), and Navy combat medical and chaplain's corps personnel. The GCE also contains combat support units, including artillery, armor (tank, assault amphibian, and light armored reconnaissance),
