Marine Air-Ground Task Force (MAGTF, pronounced MAG-TAF) is a term used by the
United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combi ...

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
A commitment device is, according to journalist Stephen J. Dubner and economist Steven Levitt, a way to lock oneself into following a plan of action that one might not want to do, but which one knows is good for oneself. In other words, a commit ...
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.

The four core elements of a Marine air–ground task force are:

aviation combat element (ACE), which contributes the
air power to the MAGTF includes all aircraft (

* The
logistics combat element (LCE), organized into battalions, regiments, and groups, has its own headquarters element for command and control (management and planning for manpower, intelligence, operations and training, and logistics functions) of its subordinate units and contains the majority of the
combat service support units for the MAGTF, including: heavy

Navy SEABEES are also part of MAGTF see https://www.globalsecurity.org/military/library/policy/usmc/mcwp/4-11-5/mcwp4-11-5.pdf
The four core elements describe types of forces needed and not actual military units or commands. The basic structure of the MAGTF never varies, though the number, size, and type of Marine Corps units composing each of its four elements will always be mission dependent. The flexibility of the organizational structure allows for one or more subordinate MAGTFs to be assigned.
