There are a number of other threads on this I think. Anyway, from reading a few, I'm not sure that any SF use Multicam. I saw a picture on this forum of a soldier wearing it, but think it is a promo shot from the crye precision website. You'll get plenty of responses on this one, seems to be a hot topic.
Just one color was removed from the pattern, the report was squeezed to 64 cm. Now this copycat "Suez" is being used by some GROM, BOR and CBS operatives here. Current uniform differs in many details and cut from what Crye or SKD presents.
If you've ever seen it in the field you will realize how amazingly effective it is.
I have seen it with my own eyes and it's just a 50/50 woodland/arid pattern. There is nothing amazing about it except the hype. If I really would have to choose a "universal" camo leaning on arid environments it would probably be this one, it's pretty good.
Completely unrelated, but your reference of "THE FIELD" somehow magically made my meter go off, is this "THE FIELD" you are talking about
