US Air ForceEdit
SG-4 was scheduled to travel to P8X-362 after read-outs of a scan indicated the minerals there were of good quality. Major General George S. Hammond gave the order for them to move out at eleven-hundred hours, however after an unscheduled return of SG-1 minus Dr. Daniel Jackson (due to Daniel's apparent death), it is unknown if the mission proceeded.

Russian Armed ForcesEdit
After an agreement of sharing the Stargate program with the Russian Government, the team becomes a Russian contingent in Stargate Command. The team was seen coming back from planet P3X-367 with a survivor of that planet's population, reporting that Nirrti was operating there. The Russian version of SG-4 is unusual in its use of Russian or Former Warsaw Pact equipment. Lt. Colonel Sergei Evanov's 4 man team were equipped with 5.56mm AK variants (at least one with an under-barrel grenade launcher), a PKM general purpose machine gun, and an SVD sniper's rifle. The two AK-variants appear to be Zastava M90-series rifles related to the Zastava M85 carried by Colonel Alexi Zukhov on the first Russian-SGC mission. Like the first Russian team, SG-4 wears Russian uniforms, but unlike the first team, SG-4 wears standard SGC shoulder patches with the exception of a Russian tricolor beret flash.

Lt. Colonel John Sheppard briefly led SG-4 when he was reassigned to Earth when the Ancients retook Atlantis. He was unhappy with the assignment, claiming that he never thought he would miss having Dr. Rodney McKay on his team. Members of the team at that point included Major Christopher Wallace and Babbis.
