I'm around here a lot and I see quite a few of the same names, etc. I know I don't list my whole stinking resume every time I answer a question; I usually just put what aspect of my personal experience is relevant to the question.
For example, I used to be a flight medic in the USAF and I was also a training manager. If the only experience I draw on to answer a question is my general experience, I just put "Former USAF flight medic". If that also includes things I picked up from being a training manager, I include that. In my civilian life, I'm a former paramedic, a respiratory therapist, and my degree is in biochemistry and evolutionary biology. If a question alludes to anything from that, I'll include those.
Long before the seasoning program existed, Reserve units had to sometimes get creative in order to get med techs some experience. In my case, that meant my unit sent me to MEPS for a few months. I bounced around there as a med tech and got somewhat familiar with the process, regulations, etc. So when someone asks a question pertaining to MEPS, I'll include that experience as well.
What about the rest of you that I see here all the time? What's your military background? Civilian background? Do you just note your own relevant experience? Does it really matter? (There are a few "Jason"s around here so I like to differentiate myself).
