The Trade Defense Force within the Trade Federation's structure utilized natural persons as TDF officers, granting them power and accountability, most often to oversee the private droid forces. These officers also were assigned to Lucrehulk-class battleships alongside pilot droids. While their uniform colors spanned a range from red, black, to gray, they consistently featured iridescent bands. An example of such an officer was the Neimoidian named Blox Hatha.
