First, before you criticize YOUR service's uniform, you should probably know what it consists of. The jacket is not black. It's dark blue. Army blue. Criticisms go a lot farther if you start with the right facts:
General Washington issued a general order October 1779 "prescribing blue coats with differing facings for the various state troops, artillery, artillery artificers and light dragoons. The Adjutant & Inspector General's Office, March 27, 1821 established "Dark blue is the National colour. When a different one is not expressly prescribed, all uniform coats, whether for officers or enlisted men, will be of that colour."
Ever notice how the Army, Navy, and Marines all use dark blue for their dress uniform? There's a reason for that.
Second, there is nothing new about 99% of the ASU. In fact, for officers, the Class A ASU consists of three noticeable changes: overseas stripes on the right sleeve, SSI-FWS pin (do some personal OPD and look that up) on the right breast pocket, and belted pants. Otherwise, the ASU is the same Army blue dress uniform that has existed since 1959. I bought one almost 9 years ago. Every formal event at USMA for officers occurred in blues, with the exception of graduation (which happened in Dress Whites) during my four years.
Why you're under the impression that the uniform is some sort of "throwback" is beyond me. You do realize that dark blue has been the traditional color of the US Army for most of its life, from the Continental Army through the Civil War and onward, correct?
The Class A green uniform was awful (not that you would know). It was a disgusting polyester blend. It didn't fit well. The gaudy green shirt was hideous. There was nothing becoming about that uniform...a uniform whose entire purpose was to differentiate Army personnel from civilians in the post-WWII years because of the surplus of the "pinks" and khakis in the general population.
There is some opinion on changing the uniform (most of us who earned our berets want everyone else to take them off). However, you'd be hard pressed to find anyone who has worn the greens who wants them back.
In fact, since you feel so strongly, I'm certain you've logged on to AKO and taken the CSA's ASU survey for uniform adjustment.
