There are always reasons (rationalizations) why it had to be exactly like that. Like so many acronyms that are really backronyms. Or, if you are familiar with IT, why a certain technology is "needed" in a product.

I'm not saying that these camo patterns don't work, but the particulars (e.g. why it had to be rectangular pixels, not hexagons or nature-inspired fractals) are often connected to fashions. My personal opinion is that dazzle camo looks cool, by the way ;)
