>Why did they try them in the first place?

With no knowledge what so ever my gut reaction is to simply point to nature. Leaves get eaten/bitten/broken/ripped, a branch might be in front of another adding depth with similar patterns, rocks and sand in a desert can vary sharply at different focal depths, urban environments can have dozens of materials in use along with random detritus and objects at various focal depths.

Pixilation was probably a logical step towards recreating these varied environments. Look at a ghillie suit that has leaves incorporated, they'll have a pixilated appearance - example: https://static5.gunfire.com/eng_pl_Ghillie-Suit-camouflage-s...

Well, that ghillie suit doesn't look pixelated to me - it just looks like it has quite a few straight-sided polygons in it.

Actually, that's what's bugging me most about this camo made from regular square blocks: it looks really easy for a recogniser to spot. No AI <spit>, an old-fashioned neural network would be enough to recognise edges, and then spot squares on a grid.

[Edit] Yeah, I get that your average stag deer doesn't have access to thermal imaging and neural networks. But this is military camo, not deerstalking camo.

The average grunt doesn't have access to thermal imaging or neural networks either, they might have a crappy Vietnam-era flashlight, their weapon system, and a reasonable compromise between number of rounds and weight as spare mags. Especially when that grunt is a "third world" fighter. Pixelated camo like ARPAT saw the bulk of its current use in Afghanistan and Iraq where the most sophisticated thing the enemy might have is a pair of binoculars and a cellphone.

The pixilation, to the human eye, is much more natural than large splotches of a few colors because terrain/vegetation/buildings in natural light have all sorts of depth and shadow variation, the pixilation is much harder to pick out than fairly large blotches of random color.
