The whole point of camo is to break up the shape of a person at a distance, not close enough to smell. Zebra are camouflaged, but close up they're dazzling black and white; look at them from a distance of a couple of hundred metres, the stripes visually blend to make them look a dusty brown, blending into the savanna background.
American camo has been bloody awful for years, and the digital ACU pattern is only useful if you're fighting in a concrete construction site. Their desert camo wasn't much better, especially compared to the British Desert DPM, which is still in use. As Wrecker says, Soldier 95 DPM is only useful in local temperate forests; fighting in multiple terrain situations needs something more sophisticated, which is where Multicam comes in.
A design created by Crye Precision, it was offered to the US military, who turned it down, sticking to their preferred Digital designs.
The British military were more open to new designs, asking Crye to create a variation of Multicam using the style cues from Soldier 95 DPM, called MTP, Multi-Terrain Pattern, because troops out in Iraq and Afghanistan were already doing something similar, mixing Desert DPM and Soldier 95 DPM to try to match the mix of arid scrub and greenery that occurs out there.
I wish I could have got a job designing camo patterns, the subject fascinates me, how mixing graphic patterns and colours can render something almost invisible from a distance.
There are lots of pretty ones, but they're very limited in actual use, because of the environment they're supposed to be used in, the 'Urban' camo which some military use, is a good case, as it's nearly always blue, when it needs to be much more neutral. Australian camo is pretty bright, but in the Australian bush, it's actually pretty effective.
It would be bloody useless in a European theatre.
