Starfleet crew devices are worn on the right collar, and Flag Officer devices are worn on both collars. Bajoran Militia devices are worn on the left collar, with General insignia worn on both collars as shown below. Starfleet Enlisted devices are not often seen, with the majority of a starship crew preferring to work without any insignia. Cadet Officers are Commissioned Officers-in-training, from Starfleet Academy at San Francisco, Terra. Provisional/Brevet devices are given to civilians who perform significant duties onboard Starfleet ships, such as the Maquis crewmembers onboard the U.S.S. Voyager.
