Gunnery Sergeant Harold "Gunny" Lewis (U.S.M.C.): the oldest member of the team (he was about 40 at the beginning of the series), Gunny had served two turns of duty in Vietnam. Gunny is the most experienced member of the team and the only one with solid tactical skills, making him automatically the team field commander. Despite his age and years of chain smoking, Gunny has enough experience to score equal or better than his comrades at field training. He's a widower and has a daughter called Cora Lewis.
