History
SG-1's original team in 2360 consisted of Colonel Jack O'Neill as commanding officer, along with Major Samantha Carter, Doctor Daniel Jackson and Lieutenant Typhuss James Halliwell and later Vala Mal Doran in 2377. In 2378, Lieutenant Colonel Cameron Mitchell, who had been offered any position in the SGC by O'Neill, chose to join SG-1, but he was surprised when he learned he was to lead the unit, and it was going to be a fresh team. SG-1 had disbanded. Carter and Typhuss were assigned to research and development labs on Starbase 400, and Jackson had moved on as well. However, Mitchell was eventually successful in reassembling the unit. In 2380, General O'Neill was promoted to General Hammond's position as overseer of Homeworld Security in Washington. In 2383 Carter and Typhuss went on their last mission with SG-1. Two years later Lieutenant General Jack O'Neill was put in command of SG-1 again, with Samantha Carter, Daniel Jackson, Vala Mal Doran and Typhuss James Kira rejoining the team and Colonel Cameron Mitchell was put in command of SG-3. In 2387 Vala Mal Doran left SG-1, the team now included Lieutenant General Jack O'Neill as commanding officer, along with Brigadier General Samantha Carter, Doctor Daniel Jackson and Captain Typhuss James Kira, the four original members of SG-1 since 2360.
