It is worth mentioning that there are some contradictory objectives when it comes to uniforms. Aside from the obvious things like fit and function for the person wearing them, which are apparently sometimes overlooked or ignored, one of the functions of a uniform is to identify the wearer as a member of certain military body. This sometimes flies in the face of camouflage, at least on the surface, but the whole issue becomes very complicated rather quickly. At any rate, this is one reason the marines have held onto their distinctive cover.
On the subject of digital patterned camouflage, the army experimented with tanks painted in a digital pattern but nothing came of it, presumably because of the difficulty in painting, compared with the value in doing so.
