It can be found on some of the uniforms of Spetsnaz soldiers in Arctic missions in campaign, Special Ops and Arctic maps in multiplayer.
Call of Duty: Black Ops
It is similar to the Urban camouflage from Call of Duty: Modern Warfare 2, but shows hints of green instead of the grayish pattern in the Urban Camouflage, although the red is the same. Parts of the weapon (such as the stock and grip) are also colored a light, wooden brown, giving the camouflaged gun a grittier feel. It blends in best with Urban Black Ops and Op 40 character models. If it is applied to the AK-47, FN FAL, Galil, RPK, and a AK74u, it would give it a blend of different camouflages yet, retains the wooden colored finish it would have without it. It appears to be based on the German woodland flecktarn pattern.
