The Vulcan rank system seems 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 subcommander and sublieutenant.
The ranks of commander and lieutenant have never been referenced onscreen, although their existence at some point in Vulcan history can be inferred by their subordinate ranks.
