This isn't a very common camo at all. In fact it is downright rare. The US developed this camo to defeat Night-Vision technology. While Thermal Imaging will always detect human presence (unless you are wearing some sort of temperature controlled suit), Night-Vision imaging just amplifies ambient light. This camo with it's square and splotch design perfectly mimics the infra-red "noise" light that effects night-vision, hence making this type of design blend in almost completely with the backround while being viewed with night-vision. Fortunately, even when being viewed by the naked eye, the design is along the lines of normal digital-urban camo.
