SG-1

Sg-1.jpg
Flagship unit of Stargate Command, presently comprised of five crew members including Colonel Cameron Mitchell, Colonel Samantha Carter, Dr. Daniel Jackson, Teal'c, and Vala Mal Doran.

SG-1 is a multi-purpose task force whose functions include first contact, reconnaissance and combat, diplomacy, initial archaeological surveying and technological assessment. Its standing orders are as follows:

  1. Open and maintain diplomatic negotiations with other worlds
  2. Obtain technologies to help defend Earth against the Goa'uld and other aggressors

SG-1 has, both successfully and unsuccessfully, executed these orders for the years Stargate Command has been operating.

SG-1's original team consisted of Colonel Jack O'Neill as commanding officer, along with Carter, Jackson and Teal'c.

In the team's sixth year of operation, after Dr. Jackson had died of radiation poisoning and ascended, Jonas Quinn of Langara took his position. Competent, reliable, and able to absorb vast amounts of information in a considerably short period of time, he was an asset and a testament to his people.

One year later Daniel fell from the ascended plane, and Jonas was called back to his homeworld to lead the political negotiations of his country, Kelowna.

In SG-1's eighth year of operation Colonel O'Neill was promoted to the rank of Brigadier General. He took command of the S.G.C., leaving SG-1 as a three-person unit, though he did go off-world when a mission required his presence.

In the ninth year, Colonel O'Neill was promoted to General Hammond's position as overseer of Homeworld Security in Washington. By this time, Lieutenant Colonel Cameron Mitchell had recovered from his injuries after defending SG-1 from Anubis's forces in Antarctica one year before. Cameron, who had been offered any position in the S.G.C. 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. Teal'c had returned to Dakara to aid his people in the development of the new Jaffa government, Carter was assigned to Area 51's research and development labs, and Jackson had moved on as well. With the presence of a new threat,however, Mitchell was eventually successful in reassembling the unit.

Vala Mal Doran, the fifth member of SG-1
In the tenth year of operation the team was expanded, with the addition of Vala Mal Doran as the fifth team member. A former host to the Goa'uld Qetesh, Vala was rescued by the Tok'ra, who removed the symbiote. Vala lived mostly on the wrong side of the law, going from planet to planet as a thief and a con artist before she met Daniel Jackson and, later, joined SG-1.

SG-1 is largely responsible for the destruction of several powerful Goa'uld, including Apophis and Anubis.
