^ NAVCOM does not utilize the rank of First Lieutenant, and so it would be impossible for the navy personnel listed here to actually hold this rank. This is a case of different authors using inconsistent terminology before the rank structure was canonized in Halo: Official Spartan Field Manual, and so these individuals should canonically be classified as either Lieutenants, Junior Grade (O-2) or full Lieutenants (O-3).
