Yukon is seen to give an arctic-like finish similar to Arctic Camouflage from Call of Duty: Modern Warfare 2. The camouflage is best used with Arctic Black Ops models as it almost completely matches their white uniforms in multiplayer. This combination makes it much more difficult for the enemy team to spot what weapons the player is carrying.
