I don't get why the branches in which very few folks are likely to need camo (basically anyone other than the army, then, and some sub-divisions of other branches like the marine corp) don't go with old-school olive drab or navy or something. Those single-color uniforms with a slightly dressy cut looked damn slick. I'd think that'd be better for recruiting or improving morale or whatever than the camo uniforms (which, often as not, are the butts of jokes and not considered at all appealing)
Then again, maybe those old styles only looked good when they were made with nice materials, like wool and heavy waxed canvas, and would look bad with cheap modern synthetics.
