be considered as roughly analogous to a notional U.S. Army (USA) corps headquarters that also contains a combined battlefield surveillance brigade (BFSB)/maneuver enhancement brigade (Army MEB). 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. The MARDIV, containing two or three infantry regiments, an artillery regiment, and several separate armored vehicle battalions (i.e., tank, assault amphibian, and light armored reconnaissance) and other combat support battalions (i.e., reconnaissance, combat engineer, and headquarters) is approximately equivalent to a notional U.S. Army light infantry division organized with two or three brigade combat teams, division artillery (DIVARTY), a division sustainment brigade, a division headquarters and headquarters battalion and others, and is reinforced with an armored brigade combat team (ABCT). (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.) The MAW, with its aircraft groups (MAGs) and air control groups (MACGs), is comparable to a notional U.S. Air Force (USAF) numbered air force consisting of a mix of several USAF wings and USA combat aviation brigades (nominally at least two of each). Lastly, the MLG and its organic logistics regiments are the USMC organizational and functional equivalents of a USA Sustainment Command (Expeditionary) and its constituent sustainment brigades. 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. For example, the I Marine Expeditionary Force (I MEF) is composed of the I MEF Headquarters Group, the 1st Marine Division, the 3rd Marine Aircraft Wing and the 1st Marine Logistics Group, all based on the West Coast. Two notable deployments of an entire MEF were when I Marine Expeditionary Force deployed in support of Operations Desert Shield and Desert Storm. I MEF ultimately consisted of the 1st and 2nd Marine Divisions as well as considerable Marine air and support units. I MEF also deployed to Somalia in December 1992 for the humanitarian relief
