Each army or organization has its own style for uniforms. Mostly, they match the overall fashion style of their people. Very few of them show camouflage patterns, as we can assume in the Altarion universe there are plenty of holographic camouflage devices. However, soldiers and mercenaries still wear them sometimes, mostly during their training.
