Efferus Bellator -
Born on Bajor under the Cardassian occupation, and soon orphaned, Bellator joined the resistance as son as he could hold a phaser. First as a child, doing his best to clean and repair the cell's equipment, then later participating in active missions. After the occupation ended, Efferus Bellator entered the Bajoran Militia, eventually earning the rank of Major.
During the Dominion War, with Bajor signing the non-aggression treaty, Bellator left for Starfleet, and soon transferred over to the Starfleet Marine Corps. He quickly rose through the ranks via mostly battle field promotions, until Reaching the Rank of Major. From there now Major Efferus's career record becomes even more obscure, as nearly all his personnel file was classified. He was Promoted to Lieutenant Colonel and recently has begun assembling various assets from within SFMC and Starfleet, and assigned to a unit known only at the 301st Marine Expeditionary Unit. It's mission, and composition remains unclear, but perhaps their unit 'name' is a hint – 'The Battle Born,' their motto, “Been there, done that, back for more!”
