Unfortunately...
The word I'm getting lately from highly reputable jungle drummers is that certain majors *may* consider (illegally) one's reserve status in their decision making. Perhaps not systematically but more likely at the level of the individual interviewers.
The way it was described to me, they like the military background but would prefer that it remain in the background. 100% out is best (retired even better, since they don't know for sure that a ten-year guy won't sign on with the local guard unit after he gets hired). If you're still participating then a traditional drill schedule would still be better than a history of years and years on orders.
Now I'm not saying the sky is falling, just that it's a factor to consider. If you have that sort of history you probably need to alleviate their unspoken concerns at the interview if you get my drift.
