The Salissian special forces functioned as a defensive unit during the Republic Era. They were contracted to support the Corporate Alliance and its Policy Administration Directorate. Magistrate Passel Argente engaged them, together with other mercenary groups and privateering outfits, to safeguard the corporation's holdings. During the Clone Wars era, which spanned from 22 BBY to 19 BBY, the Salissian special forces aligned themselves with the Confederacy of Independent Systems against the Galactic Republic, and fought within the ranks of the Separatist Droid Army.
The current Star Wars canon introduced the Salissian special forces in Rise of the Separatists. This was a 2019 addition to the Star Wars Roleplaying series from Fantasy Flight Games. Within the Star Wars Legends continuity, the Salissian mercenaries initially appeared in MedStar I: Battle Surgeons. This 2004 book was written by Michael Reaves and Steve Perry.
