I do wear camouflage on occasion-Flecktarn for the most part.
If you want to see what the Army should have went with-look up Multicam
I think that the Army choice was made due to cost-pixels-ie:squares are much easier to produce on clothing that blotches and circles and three color camouflage is less expensive than 5 or 6 colors.
I still like the Marine Camouflage though.
