The Chiss Defense Force functioned as the internal defensive fleet for the Chiss Ascendancy's military, with the duty of safeguarding the Ascendancy's domain. Under the command of Supreme Admiral Ja'fosk, it was composed of various warships, notably the Firewolf man-of-war, the Groundlion man-of-war, and the Chiss Defense Force Transport. Because it was the Defense Force's duty, Chiss Expansionary Defense Fleet ships were prohibited from engaging in activities inside Chiss boundaries.
