More camouflage is needed when leaves are shed.
Where rainfall is heavy, supports of flat-tops may require footings to counteract softening of the ground. When ground is frozen, counterbalances may be adopted to save digging holes for flat-top supports. Snow adds to the problem of camouflage maintenance because excessive loads on flat-tops may break them down. Desert areas are not always flat single-toned areas. Cast shadows in the desert are extremely conspicuous.
