Col. Nate Shepard, ex-marine. Former 2nd Fleet Attack Pilot.
During his 9 years military career, he participate in 14 successful attacks on the Vanduul. Though he never got any medals or commendations, he was praised and admired by his squad mates. He's a man you can trust in the battlefield, and someone you should have on your side, because for him, friends and family are everything. And that's exactly what kept him from advancing in the ranks, he would sometimes refuse orders to protect his squad and for that he received various punishments.
After leaving the Navy, he was recruited by Atlas Defense Industries, a freelancing company, as a combat pilot. He's yet to prove himself to his new bosses.
