: The Sedran Colonial Guard is probably a component command of whatever
: successor the UNSC established for the Colonial Military Administration.
: It's likely not anywhere near as independent as the former CMA was in
: consideration to the UNSC, but we know that it does have a modicum of
: autonomy from their command structure given Colonel Aiken's reluctance to
: have ONI assets on their territory and with their procurement of arms and
: vehicles.

: Putting all that aside, however, the SCG would still be considered an allied
: fighting force alongside the the UNSC and CMA. Within multi-national
: alliances like the former SHAEF and Warsaw Pact, and the modern NATO,
: ISAF, or the United Nations Command, all nations follow a general rating
: structure for both officers and enlisted persons to cement authority
: across joint forces. For example, a First Lieutenant in the U.S. Marine
: Corps and a Lieutenant in the British Army are equal to each other, but
: are both subordinate to a Flight Lieutenant in the Royal Australian Air
: Force, a rank equal to Captain in both their services.

So you would know that an officer in another service, in that service, held a superior rank but he doesn't hold that rank in your service. In your service he has the rank of not-a-member, AKA: nothing.

Are you saying that he would actually have that rank in your service? That he was above you in your chain of command?
