The United Nations Space Command Marine Corps serves as an orbitally-deployed force-in-readiness. As outlined in the UNSC Code and as originally introduced under the Interstellar Security Act of 2147, it has three primary areas of responsibility:
* The seizure or defense of advanced orbital bases and other planetary operations to support campaigns of the UNSC Navy;
* To act as a heavily-armed quick-reaction task force for any and all planetside operations by the Navy,
* The development of tactics, technique, and equipment used by orbital landing forces; and
* Such other duties as the Chancellor may direct

Marine Fleet Security possess two special forces trained combat elements, with Fleet Antiterrorism Security Teams and Recapture Tactics Teams. 
Fleet Antiterrorism Security Teams, also known as 'FAST' are a rapid deployment force that can maintain a high level of readiness and can deploy to any marine facility within 48 hours. They are used to bolster on site security and anti-terror capabilities and are deployed in the aftermath of terrorist activity or during terror alerts, in case of genuine attack. 
Recapture and Assault Teams, also known 'RAT' are a special force for dealing with on base emergancies. They deal with hostage situations, sniper attacks and hostile actions in or against the base, VIP protection on and around the base, joint operation with police forces in the apprehension of Marine or Navy offenders and collection of information, such as HUMINT and SIGINT of potential offenders or for concurrent terrorist or violent situations.
