Special MACO Formations

MACO Expeditionary Force:

A MEF is larger than a MACO Expeditionary Unit or MACO Expeditionary Brigade. Each MEF consists of a division as the ground combat element, up to 4 fighter groups as the aviation combat element, and a logistics group as the logistics combat element.

MACO Expeditionary Brigade:

Constructed around a reinforced infantry regiment, a composite MACO aircraft group, and a brigade service support group. The Marine Expeditionary Brigade (MEB), commanded by a general officer (usually a Major General or sometimes a Brigadier General), is task-organized to meet the requirements of a specific situation. It can function as part of a joint task force, as the lead echelon of the MACO Expeditionary Force (MEF), or alone. It varies in size and composition, and is larger than a MACO Expeditionary Unit (MEU) but smaller than a MEF. The MEB is capable of conducting missions across the full range of military operations.

In the Enterprise Task Group, this houses 5 different MEU's.

MACO Expeditionary Unit:

The (MEU) works together with Starfleet Navel forces and serves as the Starfleet's forward deployed, quick-response team, capable of accomplishing numerous missions around the universe.
The MEU, directed by a single commander, can be either an Aviator or Infantry Marine, is comprised of about 706 MACOs assigned to a normal ship. This number could be higher on a stationary installation, as part of a ship formation spread over several ships or a ship specifically designed to carry a full MEU, to top out at over 2,000 Marines.

The MEU's major elements are the Command Element (CE), the Ground Combat Element (GCE), the Aviation Combat Element (ACE), and the Combat Service Support Element (CSSE).
The CE is comprised of the commanding officer and supporting staff -- about 40 Marines, including the MEU XO, MEU Sergeant Major, Platoon Leaders, Platoon Lieutenants, Platoon Sergeants, Wing Commanders, XO's, Squadron Commander, and Squadron XO's. It provides the command and coordination essential for effective planning and execution of operations. In addition, the MEU CE is reinforced with specialized detachments, such as reconnaissance and surveillance elements, radio reconnaissance and electronic countermeasure teams, intelligence and counterintelligence assets, and advanced communications.

The GCE trains with ship Security in addition to regular training so they can provide support during ship board operations. They comprise of 2 rifle companies, armed with type IV phaser carbines, and 2 heavy weapons companies, armed with M-148 Machine Phasers, M-236 73mm Mortars and Torpedo Launchers,. The infantry poses 15 APC's crewed by 3 Marines and able to carry up to 15 infantry MACOs and equipment. The APC's are heavily armored with rifle ports on the sides and a top mounted M-148 Machine Phasers. It also contains 1 tank Platoon consisting of 8 LAV's and 60 Marines.

The composition and size of the ACE is based on the tactical situation, the mission and size, and space limitations within the ship or installation and can contain bombers, interceptor fighters, multirole fighters and or MAVs at the call for transport. The ACE includes fighter operations chiefs, fighter maintenance/support and aviation logistics/supply capabilities.


The final major element of the MEU is the MEU Service Support Group. About 40 Marines of the MSSG provide combat support, specifically supply; maintenance; replication of food/water supplies; explosive ordnance disposal; Marine security; combat engineering; medical; fuel storage and distribution; and other services to the planetary deployed MEU. The MSSG gives the MEU the ability to support itself for 15 days in austere expeditionary environments.


The air-ground task -force concept is designed to thoroughly exploit the combat power inherent in air and ground assets by closely integrating them into a single force. The MEU brings what it needs to sustain itself from space for the rapid accomplishment of the mission or to pave the way for follow-on forces. The size and composition of the MEU make it well suited for space born operations; security operations; noncombatant evacuation operations; humanitarian assistance operations.

Contingent upon "real world" situations, prior to deployment each MEU is thoroughly trained in 23 unique capabilities.
