Already googled: "terms of reference Marine Corps", "terms of reference military" "military protocol titles ranks"
I've got a character who was a Major in the USMC before she joined the FBI. She comes into contact with a junior officer, still an active Marine, while on an FBI/JAG case. Action is pretty much split between the two agencies.
A) Would he still salute her/generally give her the same respect he'd give a superior officer even though she's not an active Marine? They were in the Corps together, she was his CO and martial arts instructor- would that make a difference?
B) Would it be plausible for him to call her 'Major' rather than 'Agent'? Wikipedia says that veteran Marines have the right to be addressed by their ranks, but how often does this happen in practice?
Thanks in advance!
