I understand the need to list all three. However, there is some sense of precedence - I just don't know how the Army Reserve discharge fits into that hierarchy.
For example, after I received my RE-3 from the National Guard, while I could list my RE-1 from Active Duty, the most recent code, from the Guard, was the one used to determined my renlistment eligibility.
So, theoretically, the Army Reserve discharge seems like it would be what's pertinent before forward. However, for the life of me, I can't find what sort of document the Reserve issues upon discharge and if that document even includes an RE code.
I'm sort of rambling. I hope this makes sense.
