I don't mean to come off as petty or unappreciative, but I really don't think military personel should wear their uniforms while playing game shows, unless it is relevant (like when all the contestants do on Wheel of Fortune when they have military themes). I realize that game performance is not dependent on audience participation, but I do think it enhances a contestant's "likeability" (probably not the right word), and I wonder if it gives them a slight edge. I'm not saying there is anything improper going on, of course.
