Good start, and it covers a goodly percentage of the phonies, particularly those who were never in the Naby or other armed service at all.
However, like phony Marines, my preference is to cheerfukky introduce any of those who are suspect to others who are in fact the real thing. The results are sometimes funny, occaisionally instructive, and every once in a while, downright spectacular.
The real problem I find is that many people want to know a SEAL or other “celebrity” type. They want to be lied to, to believe it all. They’ll even go out of their way to defend the liar.
Dat be true.
