I also kind of doubt some of hteir claims on that site. One pattern for two environments with markedly different color pallettes? Color me skeptical, but it seems liek a cheapo "Jack of all trades, master of none" solution.
Yes, indeed...how could that ever work?

Seriously, though - the ACU pattern was one thing that came out of OIF/OEF. The soldiers on the ground observed that in most places in Iraq and Afghanistan, you were never in "desert" areas for very long. Even on a short patrol, you could go from flat-brown sands to gray-green river marshes to an urban environment in a matter of minutes. Most places, the DCU pattern made you actually stand out.
I wore DCUs on my IA, but from what I could see of the ACUs, they seemed pretty practical. Zippers and velcro (vice buttons), wash-and-wear, you could get at all your pockets while wearing Kevlar, and one camo pattern to rule them all.
Honestly, if they just made this thing in blue and otherwise kept the material and pattern, it'd be a perfectly suitable Navy uniform. But, where's the fun in just using a wheel when you can invent a whole new one?
