The Starfleet Marine Corps, or simply the Starfleet Marines, were the infantry forces of the Federation's Starfleet. Unlike the rest of Starfleet's service personnel, who used a naval ranking structure, the Marines used a rank structure based on equivalents of Earth infantry-based militaries, such as the MACOs. One early variant of the SFMC was the Starfleet Ground Attack Marines of the 2160s, a force that was considered inactive by the 24th century.
