The STARFLEET Marine Corps permanently stationed aboard the USS Dauntless. The 360th MSG falls under the 8th Brigade of the SFMC.
The Spirit Riders are a group of Dauntless crew-members who prefer a more formal, militaristic style of membership, with their own system of ranks and different uniforms.
In addition to joining in with Dauntless activities, including events and occupying Duty Stations across the ship, the 360th also holds its own events and conducts activities distinct from those of the mothership.
The Spirit Riders acts as a Department aboard the USS Dauntless, with the Officer In Charge (OIC) serving at the level of Department Head in the Dauntless' Senior Staff.
Sectors the Dauntless operates in. Where the Dauntless crew has an Away Team in each Sector, the Spirit Riders have a unit (or several units) embedded within that team, and so they share a name. For example, the Dauntless' 'Sigma Team' would include the Spirit Riders 'Sigma Squad'.
A Squad is the Marine equivalent of an Away Team, but a Squad consists of between one and three Fireteams (of up to four Marines each). If a Squad becomes too large, it may be elevated to the level of Platoon, and the Squad itself may be split up into more than one Squad within that Platoon.
In addition, the Spirit Riders operate in virtual space (The Dauntless' "Omega Sector") and deploys units under that designation also. All Marines serving within Omega Squad also serve in their geographically-assigned Squads, and Omega Squad allows non-Marines to join.
Due to staffing shortages, it may be necessary for a single Marine to serve in multiple capacities, in order to ensure that all necessary posts are filled. Traditionally, in such a situation, the Marine will use the highest-level position as his official post, with the lower ones filled in an "Acting" capacity.
The Spirit Riders currently consist of the following members:
