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.
[1]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.
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.
[citation needed] This comparison is based on the fact that the MEF HQG contains several of the key components of the BSB and Army MEB (viz., network support, military intelligence, military police, and long-range surveillance) resident in its organic communications, intelligence, law enforcement, and radio battalions and attached force reconnaissance company.
[citation needed] (While the tank battalion of a MARDIV has fewer tanks than an ABCT, with 58 vice 90, respectively, the MARDIV assault amphibian vehicle (AAV) battalion has four companies of 42 AAVs each and is capable of transforming an entire Marine infantry regiment into an amphibious mechanized infantry force.)
[citation needed] The MEF, which varies in size, is capable of conducting missions across the full range of military operations and to support and sustain itself for up to 60 days in an austere expeditionary environment.
The MEB, which varies in size, is capable of conducting missions across the full range of military operations and to support and sustain itself for up to 30 days in an austere expeditionary environment.
