I don't think that is true, Rocky. My ex-husband was in the naval reserves and served a 1 yr tour of duty in Vietnam. He also went to reserve meetings until he was discharged. I think it was a 6 yr commitment.
I will bow out after this, because it is certainly not an area of my expertise, but here are some posts to one thread. There was another thread today that was even closer to the content of the current thread and had similar replies. I couldn't quickly locate it. I don't know what the right answer is on this issue - that is, was Kerry in violation of the UCMJ in 1971?
