Certain teams have special duties within the Stargate program. When Stargate Command was formed there were nine SG teams created and at present there are at least twenty-one. The majority of the teams are Air Force, with some Marines and civilians. A very few alien beings have also been allowed to join. In 2004, an expedition was sent to Atlantis and listed below are the special designation teams noted thus far in that expedition and their known members.
