Colonel

Colonel is a military rank, the equivalent of which is used by the service organizations of many civilizations.

Use in Starfleet

The rank of Colonel is the most senior and final commissioned rank used by Starfleet's Marine Core. The rank is equivalent to the Star Fleet Rank of Captain.

Colonels are some of the most experienced marine officers currently in service. It is very uncommon to find Colonels serving as part of a ship based Marine Detachment. Due to their experience Colonels command brigade-sized units and as such are often assigned to large starbases and marine facilites that are spread across the Federation. Colonels can also be found in command of Starfleet vessels that have been assigned to the Marine Corp for their exclusive use.
