Spoil is widely and irregularly distributed under brush and in gullies. The visibility of wire is reduced by siting it irregularly, omitting long pickets, substituting bends for sharp angles, and following existing tracks. Artillery obtains defilade and concealment from ground observation, when mission permits, by siting in dry washes and other terrain depressions or among rocks. Vehicles are dug in when possible. Use drapes, and site to take advantage of shadows and natural concealment.
Trucks remove tarpaulins, if practicable, to reduce the size of cast shadows.
These tarpaulins may be used as sloping sides on parked trucks to break the shadow. Vehicles may be painted with colors and patterns and allowed to stay dusty to blend with the surroundings. Tracks are brushed out, if possible, or continued past a dispersed position. At depots, material is placed under underbrush or natural terrain features, draped, irregularly dispersed, toned down, dug in, covered with tarpaulins and sand, or covered to simulate existing terrain features, such as rocks. Tents are painted with canvas preservative to match the terrain.
