Any rank name system could well be distinct between empires. Between Outfits, even, since Outfits have their own ranks. I suspect since the command structure is decentralised, the only rational thing to do would be give ranks numbers and let the various outfits assign their own names to the numbers. A bit like the US armed forces do with their E1-x for enlisted ranks and O1-[i]y[/] for officer ranks that are supposed to have some sort of equivalence across Army, Navy, Coastguard and Air Force.
