A Wookiee of the male gender named Whumparrin found himself freed from an Imperial slave labor camp thanks to the efforts of an Alliance Special Forces squad. Following his liberation, he opted to enlist in the Alliance Military. Initially, he was assigned to fire-support roles, where his physical power allowed him to carry substantial equipment. He endured numerous fierce lightfights and, after proving himself, earned a promotion to the rank of sergeant, subsequently becoming a member of Team 19. Whumparrin instructed his teammates in the Shyriiwook language, which greatly improved their communication. He then became the team's heavy weapons expert and also collaborated with the droid C-7NO on administrative tasks.
