It's like referring specifically to woodland camo only as "BDU's"
Ah, thanks for clearing up the ARPAT/UCP thing.
I know about the ACU thing, despite referring to UCP as ACU from time to time. It's often a case of thinking "don't say ACU, don't say ACU, don't say ACU", and then saying ACU by accident, because it's all you're thinking. :P
