Although the full rank appears to be "wing commander," a person holding this rank was generally referred to simply as "commander."[4] In the Rebel Alliance, the rank in Starfighter Command was used interchangeably with colonel.[5]
It is unclear in many instances whether an individual was a commander or wing commander. Wedge Antilles was referred to as a "wing commander" during the Thrawn Trilogy[6], but only as a "commander" in X-wing: Isard's Revenge, which covers some of the same events, specifically the Battle of Bilbringi. Although it is conceivable that Antilles could have been promoted after the events of X-wing: Solo Command, the X-Wing book series is consistent in reference to his rank of simply "commander" despite the in-universe time gap and previous continuity of The Last Command.
