Ford intentionally rubbed Wayne's nose in it by listing the WW2 rank of Montegomery and others in that movie's credits. Wayne was one of the few who had nothing to show.
You may idolize the actor Wayne, as for me, I'll save my respect for guys like Ford and Montegomery (and dozens of others from that time who embarassed you hero by their actions).
I’m not diagnosing it as much as you are. I am simply watching a movie without pretense as most kids did back then on Saturday afternoon.....
