Shortly after 9-11 I recommended to leadership (at the O-9 Vice Admiral level) that perhaps we ought to require all military members to travel in uniform in CONUS while traveling on orders. If you recall how hysterical the population was at the time, it seemed like a logical idea for four reasons:
1 - act as a natural deterrent against possible terrorist activity.
2 - act as a calming influence on a nervous traveling public.
3 - give the military member a sense that he / she might actually be doing something tangible in those early days after 9-11.
4 - be a potential recruiting tool.
Well, the Admiral actually replied to my e-mail, thanked me for my recommendation, and then basically spanked me for being an idiot because traveling in uniform would put a member needlessly at risk by highlighting him / her as a high value target.
I thought he was kidding - better to stay low key than to offer up a possible visual deterrent? He never did acknowledge that most Sailors traveling after graduation from Boot Camp to "A" School fly in uniform, but the concept pretty much fell on deaf ears. And regardless of whether in uniform or not, you can spot the military dude a mile away. He's the one carrying the duffel bar, helmet bag, or wearing the squadron logo on his shirt.
In hindsight, it hasn't been necessary because we haven't had an event since then.
Most of my brilliant ideas fall on deaf ears, both at work and around my house...
