Thanks.

I forgot about the other theory of him never being in Vietnam which I was going to mention. I was just going off of the ribbons because it was the last thing I had read about.

I always figured, though, that he enlisted then did officer training. I just can't picture Jack at the Academy.

Then of course there's the ultimate questions: what did Jack major in? I've seen all sorts of stuff over the years of reading fanfic.
