This is among the most naive comments in this thread. You clearly know very little about the about the history of military personnel, their credibility, and their political affiliations. You should look into Seal Team Six as an example. Some of them have turned out to be rabid crackpots.

Being associated with the military confers absolutely zero marginal credibility over any other citizen. If anything, it's the opposite since there's a known conservative bias in military and law enforcement - dovish liberalism threatens their values and their power.
