SG-15 has been an active team with Stargate Command, often for combat missions. For several years, the team was led by Major Pierce.
The first reference to an SG-15 mission is a joint one carried out with SG-14 and likely one other team on P6Y-325 (4.05 "Divide and Conquer"). The mission was a routine "meet and greet" with the primitive Lazairian people. Just after the sun set, death gliders attacked the village. SG-15, closest to the Stargate, were under heavy fire as members of SG-14 tried to support them against Jaffa scattered around the clearing. Col. O'Neill later noted that six SG team members died during that battle, meaning that likely all of SG-15 perished on P6Y-325, since at least three members of SG-14 survived.
A reconstituted SG-15 were the first team to arrive on P4X-639 (4.06 "Window of Opportunity"). There they found an Ancient device amongst ruins and an alien archeologist named Malikai. The team took lots of video footage of the writing on the pillars and table–enough that Daniel Jackson later referred to it as "400 pages of alien text" as well as several images of the increased solar activity on the planet. Two weeks later, SG-1 was scheduled for a follow-up mission to P4X-639. Major Carter was interested in setting up a remote observatory to study the coronal mass emissions SG-15 detected and Dr. Jackson wished to meet Malikai and study the Ancient ruins. When Malikai activated the Ancient device–a broken time machine, the day kept repeating itself over and over again for several planets with only O'Neill, Teal'c, and Malikai aware of the repetition. SG-15's videos from their mission were used to try and translate the machine and help SG-1 fix the problem.
SG-15 was eventually taken command of by Major Pierce, formerly of SG-2. When SG-1 met the Aschen, suspicion arose when the SGC realized the Aschen's homeworld could be P4C-970, a planet that was locked out of the dialing computer because of a warning note with O'Neill's blood that came through the Stargate (5.10 "2001", see also 4.16 "2010"). The only way to know for certain if the Aschen were the reason the warning was given was to send teams to the three other possible planets in that neighborhood. SG-15 was to go to one of these planets; SG-3 and SG-12 were to check out the other two. The Pentagon, worried SG-15's investigation could compromise promising negotiations with the Aschen, ordered the mission scrubbed.
Pierce was still in command of SG-15 when they went on a joint mission with SG-12 to a Tok'ra base (6.09 "Allegiance"). While there, the Tok'ra were attacked by Goa'uld. SG-12 was wiped out in the first wave. SG-15, some members injured, helped the Tok'ra evacuate to Stargate Command's Alpha Site. When it was discovered a saboteur may be amongst the Rebel Jaffa, Tok'ra and SG teams at the site. Col. O'Neill ordered SG-15 to guard the Stargate and let no one near it. Later, they discover it is a cloaked Ashrak sabotaging their equipment and building the distrust. Searching for the saboteur, several individuals were killed, including Captain Grier, possibly one of SG-15. The Ashrak attacked the Stargate and stole Pierce's GDO. At least one member of the team was hit by friendly fire in the confusion.
When SG-1 encounters survivors of a crashed ship called the Seberus on P2X-005, they also came under attack by "hostile aliens" (6.18 "Forsaken"). Carter and Jonas returned with one injured survivor, Tanis Reynard and requested the opportunity to study the ship more. Hammond ordered SG-15 to join Carter as backup. SG-15 covered the Stargate as Carter returned to the ship. Hammond dialed P2X-005 to alert SG-15 that Jonas Quinn and Tanis Reynard were returning. SG-15 remained unaware that the Seberus "survivors" were escaped prisoners from the ship. The "hostile aliens" were truly their guards. When Jonas Quinn returned as hostage to Reynard and her fellow prisoners, Jonas signalled to O'Neill with his GDO and SG-15 was ordered to let the group pass through the Stargate–where they were promptly arrested at Stargate Command.
SG-15 backed up SG-1 on P4S-237 to try and help the people free themselves from the Goa'uld Lord Mot's control (6.21 "Prophecy"). Jonas Quinn, under medical supervision for strange headaches and prophetic visions, and Carter–because of Jonas "seeing" her injured, remained on Earth. The remainder of SG-1 and SG-15 set up to ambush Mot's group when they arrive through the Stargate, but they don't realize that a local, Chazen, alerted Mot to the plan. The teams are captured by the Goa'uld. Another local, Natania, drugs the guards and helps the teams escape. The teams reach the Stargate, which was to be a planned ambush by Mot to kill the teams and invade the SGC after SG-15 sent their GDO code, but Hammond's actions based on another vision by Jonas Quinn had taken some actions which ended up ruining Mot's plans. SG-1 and SG-15 survived and the people of P4S-237 were freed. The locals planned a feast in honor of the two teams.
SG-15 again came as tactical military assistance when Jack O'Neill requested the team and SG-11 to return with him to Kelowna after Anubis arrived at the planet (7.02 "Homecoming"). Hammond would not allow a full military force, but he approved of O'Neill's workaround as "technical advisors" to support the Kelownans after O'Neill asked them to resist handing over naquadria to the Goa'uld. They also hoped to have support from Ba'al in an "enemy of my enemy" temporary alliance. Commander Hale of Kelowna was not as impressed at the eight-man backup, despite O'Neill's assurances they were eight "good men". The teams established a perimeter around the capital's square, near the Stargate. Major Robbins was in charge of one of the teams, but it's uncertain whether he was affiliated with SG-11 or SG-15. Anubis's attack was foiled when Ba'al arrived and destroyed the ship.
Pierce was no longer in command of SG-15 by Season Eight, having been promoted to Colonel and commander of the Alpha Site (8.10 "Endgame").
SG-15 was one of seventeen teams taking part in an offworld SGC celebration (possibly on P2C-106), (10.06 "200"). The celebration may have been for Lt. Col. Mitchell's 200th trip through the Stargate, but in any case took place on the landmark (and meta) 200th episode of Stargate SG-1.
The final mention of an SG-15 mission was on Earth. After Vala Mal Doran was kidnapped by the Trust, SG teams simultaneously raided several known Trust warehouses (10.08 "Memento Mori"). The warehouse SG-15 hit was the correct one, and the team got into a large firefight with Trust operatives. At least one team member was able to reach Vala and help free her, but was killed by a wounded Trust operative. The warehouse exploded from a booby trap as Vala escaped, and while she survived, all members of SG-15 and three of the local team were killed in either the explosion or preceding firefight.
