Squad six was a squad in the Armed Forces of the Galactic Empire. During the Imperial Era, squad six was part of the Imperial garrison charged with the defense of Fortress Vader on Mustafar. During that time, squad six took part in the Battle of Fortress Vader against Mustafarians who sought to push the Empire off their world. Eventually, squad six was overrun and the entire garrison was destroyed.
