UCP (Universal Camouflage Pattern) is the more commonly used name for the pattern in official sources.
Granted its maybe not the best pattern for North American forests, it looks like it'd work well in spring when there's a lot of dead vegetation/leaves and in mountainous terrain (seen a few pics of that, it was quite effective). There's actually some pretty good pics (not biased like the Multicrap ones) of UCP working.

I think part of the problem is there's a lot of bad pics of UCP where it looks blue-ish grey (bad color balancing?)
UCP-D looks interesting.
