Federation Marines are members of the Galactic Federation Marine Corps, also known as the GFMC, who wear advanced powered armorsuits. These suits allow them to use potent weapons and resist heavy damage in battle; few can match them in combat. One of the most common sights on Federation worlds, the Marines are the rank-and-file soldiers of the Galactic Federation. A quadruplet of elite Federation Marines, the Federation Force, are the titular protagonists of Metroid Prime: Federation Force. Some Marines in Corruption were voiced by Troy Baker.
