Dunno but for 28mm figures any pixels will appear as dots. I found dotting on green and grey-black patterns over a base of Vellejo Green Brown worked pretty well for my USMC Force Recon. Pixelated camouflage is just another fashion trend anyway and one that seems to be going out of fashion. MultiCam, whish has been adopted by the British Army, is used by a lot of the SF fraternity and will in all liklihood replace the current US Army pattern isn't a pixelated scheme. It relies on blending colour swatches, a total of seven in the current version. Alas when you are painting minis, it's harder to get right.
Yeah the word is from some of my buddies that are still in, is that force's going to Afgnastan are being issued it currently and it will slowly fase out the ACU over there. State side units will still wear the ACUs for garrson duty at this time.
