The Vulcan rank system seems to have been similar to the system used by the Romulans, perhaps suggestive of a common origin. Vulcans and Romulans are the only species in Trek shown to hold the ranks of sub-commander and sublieutenant.
The ranks of commander and lieutenant have never been referenced on-screen, although their existence at some point in Vulcan history can be inferred by their subordinate ranks.
