J-Squadron, alternatively referred to as J-Squad, represented a squadron of cadets undergoing instruction within the Resistance's Starfighter Corps. This group was under the command of Jothan Tiaan Jerjerrod, a human male. Their training spanned several months at the facility known as The Yard, prior to some members becoming embroiled in an incident concerning the reprogramming of the droid AG-90. Following Dec Hansen's activation of the base's shutdown, the squadron faced disciplinary action, leading to its dissolution and the reassignment of its members to a mission situated on Vodran. The cadet roster comprised Mattis Banz, Lorica Demaris, Haal, J'mi, Leeson Juben, Klimo, Sari Nadle, along with an Aqualish. Subsequently, Cost Niktur and Ymmoss joined their ranks after they managed to break free from imprisonment on Vodran.
