Group AC consisted of a trio of TIE/ad starfighters forming a squadron. These fighters were reassigned from the Ton-Falk-class escort carrier known as the Tropsobor to the Victory I-class Star Destroyer called the Protector amidst the Sepan campaign. Maarek Stele, along with other TIE squadrons, provided defense against an attack by the forces of Dimok and Ripoblus.
