More to the point, if dress of the day is service dress, members aren't actually authorized to wear something "above" that to be comfortable. That's the point of dress of the day, isn't it? To mandate what the member is required to be wearing on a daily basis?
Anyways, this whole entire "no rolling sleeves at all" thing to me seems to be a decision that is just emblematic of what I consider to be the worst traits of the Army. Valuing appearances and conformity over everything else, and not giving a hoot about the comfort or well being of the people under your command. I just feel sorry for the Air Force folks who got wrapped up in this crap just because the rules for wearing CADPAT got delegated down to the commander of the Army.
