Active Camouflage

Active camouflage is a sort of camouflage that mimics the environment around it, similar to the chameleon. It can render a soldier almost completely invisible. Where teleportation solves the problem of mobility and transport, active camouflage solves the problem of how to effectively deny target acquisition for the enemy. An army that can move across great distances instantly, as well as one that cannot be seen, is synonymous with the the powers possessed by the demonic legions of Hell itself.
