Starfleet Marine Corps Organization
The Starfleet Marine Corps is organized within Starfleet, the Commandant of the Marine Corps is commanding officer of the SFMC. S/he is responsible for organizing, recruiting, training, and equipping the Marine Corps so that it is ready for operation. The Marine Corps is organized into three principal subdivisions: Headquarters Marine Corps, the Operating Forces, and the Supporting Establishment.
The Operating Forces are further subdivided into three categories: Marine forces assigned to Unified Combatant Commands, Marine Corps Security Force Regiment which are the men and women guarding Starfleet installations, and Marine Security Guard detachments at Federation embassies.
Marine Corps Forces are further divided into Marine Forces Command (consisting of I Marine Expeditionary Force), Marine Forces Beta (II Marine Expeditionary Force), Marine Force Delta (III Marine Expeditionary Force) and Marine Force Gamma (IV Marine Expeditionary Force).
Marine Aerospace-Ground Task Force
In the today's Starfleet Marine Corps, the basic framework for deploy-able Marine units is the Marine Aerospace-Ground Task Force (MAGTF), a flexible structure that can vary in size. A MAGTF is composed of four elements: the command element (CE), the ground combat element (GCE), the aviation combat element (ACE) and the logistics combat element (LCE). A MAGTF can operate independently or as part of a larger coalition. It is a temporary organization formed for a specific mission and dissolved after completion of that mission.
The MAGTF structure reflects a strong tradition in the Corps towards self-sufficiency and a commitment to combined arms, both essential assets to an expeditionary force often called upon to act independently in discrete, time-sensitive situations. The history of the Marine Corps as well has led to a wariness towards relying too much on its sister services, and towards joint operations in general.
A MAGTF varies in size from the smallest, a Marine Expeditionary Unit (MEU), based around a reinforced infantry battalion and a composite squadron, up to the largest, a Marine Expeditionary Force (MEF), which ties together a Division, an Aerospace Wing, and a Logistics Group under a MEF Headquarters Group.
The four Marine Expeditionary Forces are:
- I Marine Expeditionary Force located at
- II Marine Expeditionary Force located at
- III Marine Expeditionary Force located at
- IV Marine Expeditionary Force located at
