According to scifi.com, three nuggets are killed and four vipers detroyed in the Battle for the Tylium Asteroid. The three onscreen deaths were Fireball (squadron leader, obviously not a nugget), Chuckles (nugget, Hand of God) and Stepchild. Since she resembles [nugget #3] well enough, we may therefore assume that she was among their number, and infer her rank as Cadet.
