Cameron Mitchell, or Cam is a Colonel in the United States Air Force and the current leader of SG-1, since 2005, taking command from Lt. Colonel Samantha Carter.
Given the callsign "Shaft", Mitchell flew an F-302 fighter-interceptor, leading the Tau'ri forces in the Battle of Antarctica in 2004.
After making a full recovery, he requested to join SG-1, only to discover the other members, Carter, Teal'c and Dr. Daniel Jackson, had all left the unit to follow different paths. However, after a few months, he got the team back together. For most of his time as commander of SG-1, he fought the Ori. He was promoted to full-bird colonel in 2008 and continues leading SG-1 to this day, Mitchell's leadership style being where everyone involved participates to the fullest of their abilities and defers to the specialist quickly when needed.
