b. CPs and logistics emplacements are easier to camouflage and better protected if located underground. Antennas can be remoted to upper stories or to higher buildings based on remote capabilities. Field telephone wire should be laid in conduits, in sewers, or through buildings. c. Marines should consider the background to ensure that they are not silhouetted or skylined, but rather blend into their surroundings. To defeat enemy urban camouflage, Marines should be alert for common camouflage errors such as: Tracks or other evidence of activity Shine or shadows Unnatural color or texture Muzzle flash, smoke, or dust Unnatural sounds and smells Movement. d. Dummy positions can be used effectively to distract the enemy and make him/her reveal his/her position by firing on them. e. Built-up areas afford cover, resources for camouflage, and locations for concealment. Following are the basic rules of cover, camouflage, and concealment to which Marines should adhere: (1) Use the terrain and alter camouflage habits to suit your surroundings. (2) Employ deceptive camouflage of buildings. (3) Continue to improve positions. Reinforce fighting positions with sandbags or other fragment- and blast-absorbent material. (4) Maintain the natural look of the area. (5) Keep positions hidden by clearing away minimal debris for fields of fire. (6) Choose firing ports in inconspicuous spots when available. Note: Remember that a force that covers and conceals itself has a significant advantage over a force that does not. Military Operations on Urbanized Terrain A - 71
