Royal Manticoran Marine Corps
The Royal Manticoran Marine Corps is a component of TRMN. Members of this component tend to focus on the Marine Corps aspect of the stories. RMN ships with a sufficient number of members who are Marines may form a Marine detachment, or MarDet. They wear the uniform of the RMMC and are addressed by Marine titles.
Within the context of the stories, Marines form an integral part of a ship's crew; they man the ship's weapons, are crucial to damage control and are used for boarding parties or to provide a quick-reaction ground force on a planet's surface. While Marines can be deployed as a garrison force, such arrangements usually last only until they are relieved by Army units.
Marines can be promoted when they have meet the "Time in Grade", the "Time in Service" and passed any necessary courses. The courses can be found here:http://wiki.trmn.org/wiki/index.php/RMMC_Enlisted_Training_Center
