In a desert, or in any open barren terrain, the lower an object is to the ground, the smaller is its shadow and the easier it is to conceal from aerial observation. When time and soil permit, every effort must be made to dig in important vehicles. Not only are they more easily concealed, but they are also protected from bomb and shell fragments.

    Figure 58 illustrates the steps taken to conceal an important special vehicle in a theater of operations. An excavation is made, with a slanting approach. The vehicle is parked in this pit (a). Sandbags are used to form a revetment for protection against shell fragments (b), and the whole installation is covered with a garnished twine net (c). The net is sloped gently out to the sides and staked down. Finally, vehicle tracks to the position are brushed out or covered. The result shows that even in open terrain, a large vehicle can be given a good deal of concealment.
