- See Oliver for other articles with titles that contain, either by relationship or by coincidence, this character's surname.
For the purposes of this wiki, a Starfleet ensign's uniform insignia is shown, as this was the most likely for Oliver to have worn while holding an ensign rank. There is a slight possibility, however, that Oliver was a provisional officer from the ship's Maquis crewmembers. In that case, the rank insignia on Oliver's Starfleet uniform would have been one of the different Federation Starfleet ranks badges given to those members of the crew. See also Federation Starfleet ranks (2360s-2370s) and Starfleet uniform (2366-2373).
