|Starfleet Military Assault Command Operations|
|Service type:||Special Assault Forces|
|Dates active:||from ca. 2130s|
|Primary missions:|| planetary defense,|
Starship excursion operations
|Motto:||Semper Invictus ("Forever Invincible")|
The United Earth Military Assault Command Organization (commonly abbreviated as MACO, MACO Corps and alternately called Military Assault Command Operations) was a military organization. The MACO motto was Semper Invictus, Latin for "forever invincible". (ENT - The Romulan War novel: Beneath the Raptor's Wing, STO novel: The Needs of the Many; ST reference: Star Trek Encyclopedia)
The MACOs (pronounced "MAY-ko") were not originally associated with Starfleet. As of 2153, MACO weapons and technology were three years more advanced than those of United Earth Starfleet.
The military official that oversaw MACO was a High General. MACO posts included Atlanta, Georgia and the Janus loop. Training posts included the old United States Army Station at West Point in New York, and others in Chicago, San Francisco, London, Paris, Berlin, Moscow, Beijing, Tokyo, and ShiKahr on Vulcan. (Star Trek: Enterprise)
Following the foundation of the United Federation of Planets, the organization was disbanded. (TOS movie: Star Trek Beyond)
Known as Starfleet Military Assault Command Operations (commonly abreviated as SMACO or MACO) during the time of the Federation in the 24th century. In 2375, following the end of the Dominion War, MACO was integrated into Starfleet, and its members were reassigned to the operations division of Starfleet. However, they retained their operating ranks and some independence from Starfleet. (Star Trek: Intrepid)
The Military Assault Command Operations was founded in 2133, as a military alliance by the European Hegemony and several western nations, including the United States and Canada. It later transitioned as the primary ground force of United Earth.
In 2151 through 2160, MACO was commanded by High General George Casey. (Star Trek: Enterprise)
A detachment of troops commanded by Major Joss Hayes was assigned by High General Casey to the starship Enterprise for its mission into the Delphic Expanse in 2153, upon request by Captain Jonathan Archer. They saw their first action six weeks into the mission; in September, Hayes and a six-man team rescued Archer, Commander Tucker, and Kessick from the clutches of a trellium mining planet. (ENT episode & novelization: The Expanse)
Since the Earth Starfleet was not a military organization, MACO troops were used to fulfill any military functions needed aboard Earth Starfleet vessels. MACOs fought in the Undine War in the 25th century. (STO novel: The Needs of the Many)
In 2155, during the Earth-Romulan War, the Military Assault Command Operations were heavily involved in the ground scale engagements against the Romulans. They were known to have suffered losses at Deneva and Berengaria VII by sneak attacks from the Romulan Star Empire. Due to Starfleet's limited number of ships, there were fears on how to get MACO troopers to the front lines without adequate ship support. (ENT- The Romulan War novel: Beneath the Raptor's Wing)
Following the Romulan War and the founding of the United Federation of Planets, most of MACO was absorbed into the Federation Starfleet as Starfleet Security, with the rest becoming the Starfleet Marine Corps. Some MACO officers joined Starfleet, such as Major Balthazar M. Edison, who became captain of the USS Franklin. (ENT- Rise of the Federation novel: A Choice of Futures, TOS movie: Star Trek Beyond)
In 2375, following the end of the Dominion War, MACO was integrated into Starfleet, and its members were reassigned to the operations division of Starfleet. However, they retained their operating ranks and some independence from Starfleet. (Star Trek: Intrepid)
Some Starfleet ships had MACO squads on board such as the USS Gemini-A, a Excelsior-class starship, the USS Gemini-B, a Ambassador-class starship, commanded by Major George Travis and the USS Intrepid, a Galaxy-class starship and the USS Intrepid-A, a Sovereign-class starship, commanded by Major/Corporal Sascha Money. (Star Trek: Intrepid)
MACOs have consistently demonstrated a level of competance in small-unit-tactics, close-quarters-combat, and even hand-to-hand combat that put Starfleet Security from any era to shame. (Star Trek: Intrepid)

Uniforms and equipmentEdit
The MACO uniforms and equipment were worn by United Earth military personnel in the 22nd century and later in the 24th century by MACO officers of the Federation. (Star Trek: Enterprise, Star Trek: Intrepid)
The standard combat uniform worn by MACO personnel was a two piece uniform with matching undergarment, gloves and boots. The overall color of the combat uniform and boots was gray with white, black, and brown camouflage effects. The belt, gloves and undergarments were a brown color. This uniform was worn in and out of combat. (Star Trek: Enterprise, Star Trek: Intrepid)
MACO issued its own environmental suits, distinct from the ones used by contemporary Starfleet personnel. MACO EV suits had a silver color, with support systems located in a backpack. The helmet featured two lights in a more central position than on the Starfleet suits. (Star Trek: Enterprise)
The MACOs still used this environmental suit in the 24th century. (Star Trek: Intrepid)
Arms and equipmentEdit
- Stun baton (22nd century, 24th century)
- Stun grenade (22nd century, 24th century)
- Phase pistol (22nd century)

An equipment belt was normally worn, carrying the stun baton, two stun grenades, the holstered phase pistol, three phase pistol charges, and a hand scanner. (Star Trek: Enterprise)

The MACO Enterprise mission patch depicted a mako shark. (Countdown text commentary, ENT Season 3 DVD) The mission patch was designed by Scenic Art Supervisor Michael Okuda. (Star Trek: Costumes: Five Decades of Fashion from the Final Frontier, p. 217)
The patch was later used during the production of Star Trek Beyond, modified to feature the name of the USS Franklin rather than Enterprise. The MACO patch was stenciled on the sides of PX70 motorcycles used in the film  and was printed onto T-shirts given to the cast and crew.
MACOs after 2161Edit
There have been no references to any separate Earth military after the final MACO appearance in 2161. There has only been one explicit mention of a Human holding an army rank after this point in history, and the officer in question – Colonel Patrick West – was shown to be a member of Starfleet in 2293 wearing a vice admiral's rank (which would make him a lieutenant general in the army).
Star Trek Beyond co-writer Doug Jung once noted about the disbanding of MACO, "I thought it'd be kind of interesting [....] You can make some modern analogies in terms of like the CIA, which is – you're asking these people, you're training them their whole lives to see the world one way, and then you say, 'Oh, by the way, you're now obsolete, but we'd like you to do [this other thing].' It's tough."
The novelization of The Expanse states that Captain Archer was initially uncomfortable with the notion of military personnel serving aboard Enterprise but reconciled himself to the idea, given that it seemed as if the MACOs would be beneficial to the search for the Xindi weapon. The same novelization also suggests that MACO be pronounced "Mah-co" rather than "May-co", despite the latter being the commonly used canon pronunciation.
In the Romulan War Pocket ENT novel Beneath the Raptor's Wing, the "O" in MACO stands for "organization" instead of "operations," making the MACOs' proper title Military Assault Command Organization.
According to the novel The Needs of the Many, MACOs continued to exist into the 25th century.
In Star Trek Online, the MACOs are an elite Starfleet force, using the standard Starfleet ranks, rather than the army/marine style. They have allied with the Klingon Honor Guard to form Task Force Omega, for the purpose of fighting the resurgent Borg Collective. Starfleet player characters can obtain specialized MACO armor and weaponry through the completion of Special Task Force missions against the Borg. It is widely considered to be some of the most powerful ground equipment available.
