I have used MC for a couple of years and it works extremely well in different terrains; grass, high/low desert, forest. If you don't move, near or far (no black outline in the distance), it blends perfectly. Saves in planning and terrain movement selection. Only wish they made it in quieter materials.
I think, not positive, that the military passed on it just before the first digi's came out, the reason being price. (probably because they already spent so much on the digital crap). They should of let the Quiet Professionals test it themselves, then we wouldn't be seeing squares all the time
