T-SF was a group of three Utility Tugs used by the Rebels. The tugs were to deliver pilots to Y-wings, while their sister group T-SE did the same to shuttles Revt to defend a supply depot conisting of three containers Duce from Imperial forces intending to destroy everything. The two stormtrooper transports Bultz powered up to provide cover, but the battle ended in favor of the Empire and the tugs were destroyed in the battle along with everything else. The battle was then recreated and adapted in the Combat chamber to train future pilots such as Maarek Stele.
