Anagram posted... Starfleet Command Ranks
Completely unremarkable. It's just the real US Navy ranks, except with "crewman" instead of "seaman." The only thing I can think of to say about the ranking structure is in ENT, Trip is a Commander while T'Pol uses the Vulcan ranking system, which has the rank Subcommander, but she outranks him, which confused the hell out of me when I first watched the show. It's not even that Subcommander is equal to Commander, because the Vulcans also had a Commander rank. Completely impossible to explain.
If the Vulcan rank system is the same as the Romulan rank system, then it's easy to explain. In that case Subcommander would indeed be equal to the Starfleet rank of Commander, because Romulan ships have Commanders instead of Captains.
