It also depends on the situation and how close the two careers are to each other.
How about - just thinking off the top of my head - the following two or three scenarios, all involving ground pounders:-
1. A Sergeant leaves his Regular Army - O after so many good terms, good standing with his unit and the force, and joins a merc unit. What'd be his rank in the merc unit?
2. A Marine Gunnery Sergeant joins the same merc unit. Same question.
3. And again, only it's with an Officer - a Major.
I really doubt they'd want to start again as an E1 or an O1, respectively. Because in many cases with servicemen there's money, but there's also pride. And while money's probably the biggest incentive - I mean, why else would they want to go freelance unless they'd
really dropped the ball and got the General's daughter pregnant or something unless they were going to be offered more money than they've ever seen - nevertheless, there's the reassuring weight of those stripes, that brocade, that's hard to shake off.
