I am reminded, for some reason: Why is it that U. S. Army personnel nowadays wear cammies and combat boots virtually everyplace they go, on base and off, travelling in civilian commerical aircraft, et cetera, et, cetera, et cetera???
Its a good, honorable and serviceable uniform, but those army “greens,” or o.d.s, or whatever they were called, looked mighty neat. Being Old Navy, I wore my blues generally (or whites in summer) while off base/ship mingling among the civilian populace, not dungarees or their equivalent. Just curious.
The rules have changed. Until very recently, more so for some services than others, they could not wear "utility" uniforms to off base/post establishments, beyond a quick stop at the mini-mart or gas station, or a stop at the drive through at the choke and puke.
As part of a trend to "everyone a warrior", they are encouraged to do so. Of course BDUs and ACUs (and the Marine and AF equivalents) are much better looking than the 50s - 80s green fatigues. Even just before 911, the Air Force guidelines were not to wear "camo" off base, except as noted above. But all that's changed now, mostly for the better.
They also wear them, or in the case of fliers "green bags" when assigned to what amounts to "office work". That I don't care for, I think it's sloppy and unprofessional. I wouldn't make them wear Class A's\Combination 1 (or equivalent) or anything else with a tie, but the military equivalent to "corporate casual" would be fine, all year round.
