The 4th Squad functioned as a unit within the Alliance Military, specifically as a squad of Wilderness Fighters.
During the Battle of Hoth, this squad was integrated into the battalion led by Major Bren Derlin. Corporal [Jobin], who was the offspring of Mon Momtha, served as their commanding officer. Their designated location was Echo Station 5-7. The squad's members also included individuals named Roj, Jielu, Grond, and Sora. They observed that the ion cannon was being targeted by an assault force comprising stormtroopers and an All Terrain Scout Transport. Subsequently, they launched an assault to defend the cannon, successfully safeguarding Rebel shuttles through the incapacitation of an Imperial Star Destroyer. Although the majority of the squad perished in the conflict, a minimum of two soldiers survived and successfully conveyed a vital communication to Mon Mothma.
