Lt. Colonel Cameron Mitchell is the commanding officer of SG-1, following the promotion of Jack O'Neill to Major General and the disbanding of the original SG-1 team. Mitchell is a daring fighter pilot, who led an F-302 squadron in the battle with Anubis's forces over Antarctica.
Mitchell and his co-pilot, Adam Banks, were shot down during the battle, in which they destroyed an enemy Al'kesh. Banks was killed, but Mitchell survived, though seriously injured. He was awarded the Congressional Medal of Honor, and gradually recovered. O'Neill promised him anything he wanted if he recovered; Mitchell chose SG-1 because he wanted to be on the front-lines with the best.
Upon his arrival at Stargate Command, Mitchell learned from new base commander General Hank Landry that Samantha Carter and Daniel Jackson had taken new assignments, while Teal'c had left Earth. Cameron was to lead the new SG-1 ... but the Colonel had difficulty finding anyone worthy of joining his team. He appealed to the former members of SG-1 to return, but was initially turned down. However, events took a hand, and he finally found himself in charge of the team he really wanted.
Mitchell is a highly competent and enthusiastic leader, dedicated to military service and excited to be a part of the team he has until now only watched from the outside.
