Gonna go by series:
Star Trek Crew member : He'd be Worf. Chief security, repel boarders, board other ships, worf was also tactical officer. Orrin's tendencies would make him not good enough for a Riker
Star Wars: If not Jedi, Pilot of some sort of fighter ship. If Imperial, he'd be akin to Rommel from world war 2, he'll fight the war, but will overturn morally questionable orders.
