Colonel David Dixon has served as the commanding officer of SG-13. A tough military officer with a wry wit, he is married and the father of four children whom he loves deeply despite describing parenthood as more hazardous than off-world missions. On a standard recon mission to P3X-666, he and his team, including Balinsky, Bosworth, and Wells, discovered the ruins of an Ancient city before being ambushed by an army of Jaffa. O'Neill led the rescue mission, and Dixon and his men survived the bloody firefight.
