Free Commandoes

The Free Commandoes were a special unit of elite Starfleet marines that were attached to Starfleet Intelligence. They were formed shortly before the end of the Earth-Romulan War when the Starfleet Marine Corps was formed and the Starfleet Intelligence Command's Intelligence Assault Units were disbanded. Their formation led to senior officers tending to think of their new marine counterparts as "grunts" which promoted inter-service rivalry.
