I sorta get your point. I am a 60 yr old Officer. I shine my shoes, press my uniform, and have haircuts religiously. I maintain the CAF standard, as varied as it is. I also like beer, so I will never be featured in a recruiting poster. My six pack from my twenties has evolved into a keg. I am also pretty good at my job, appearance be damned.
My point was that we don't need to be all Dolph Lundgren lookalikes, with impeccably tailored uniforms from "A Few Good Men" to be effective. As I stated earlier, some of the best soldiers I have met (and I assume sailors, and AF pers) don't fit that profile, but they do get the really important shit done, and at the end of the day, that is what I expect from them.
