Disagree with you here. My best friend is Ranger qual in the 101st so I get this info first hand. The ACU is crap. Sure its light weight, but its concealment is majorly lacking. Also, the velcro ends up trapping sand and becomes useless, the zippers are crap, and once you stain it you might as well throw them away.
While some if this is might just be bitching I think the concealment portion is kind of a big deal. They are doing dismounted patrols in Afghanistan and blending in certainly helps.
Yes the black beret for everyone was stupid (I agree). But generally the Army likes to incorporate things SOF is doing because they are doing it for a reason: It works! Not because it looks cool, but because its functional.
I participated in an Army FTX (as OPFOR) in a woodland environment and it was painfully easy to spot them trying to be sneaky doing a recon while in ACUs.
