My opinion of Camo is ACU all the way. It seems to works best in Prescott, here in the valley, whether your in riverbeds or even out in a bunch of scrub brush.
We have a lot of bluish green trees and shrubs out here. Even though Phoenix is a desert, it's not a desolate desert. Its a very green desert compared to some.
Creosote, Palo verdes, etc. give a lot of cover. ACU blends very well not only due to its pattern but also its color. I have heard some speak down on ACU. The only
reason I chose ACU is because I wanted to have the best camo, other than getting a Ghillie suit, it works perfect.
I think Multicam and Digital Woodland are a close 2nd to ACU.
In my opinion, the desert patterns work well if you have sparse plant material and more rocks and sand than anything else. Obviously the brown in these patterns
blend with the ground especially in the summer where many of the plants and weeds are dead.
In the wintertime, Phoenix can have a lot of green weeds pop up and exposes the Desert patterns.
Even in the snow you can get away with ACU.....
By the way, if you are looking for some 3 color desert or woodland BDU's, I have some if you are looking to buy some...
