Guardian Squadron was under the personal command of General Horton Salm. The Squadron took part in the failed attack on Borleias six and a half years after the Battle of Yavin. Defender Wing was instrumental in saving Rogue Squadron from certain destruction during the assault.
At some point during the Galactic Civil War, Guardian Squadron was equipped with BTL-S8 K-wing assault starfighters.
