180. The mobility of motorized infantry allows them to place their protective posts at a considerable distance from rest areas in order to make use of natural defenses. This often economizes manpower and guards the troops from surprise attack by armored forces. Obstacles should be constructed. Motorcycle messengers must be allotted to insure rapid communication between the advance guard and the main body.

181. Reconnaissance by fighting patrols gives the best protection against surprise. For the immediate protection of resting troops, local covering parties will usually be sufficient.

182. Concealment of the large number of vehicles can be achieved only by wide dispersions.

The division and disposition of troops according to the positions they occupy in march columns facilitate the issue of orders, and accelerate resumption of movement.

183. Vehicles must be so disposed that they are concealed from air observation.

184. The routes to and from the rest area must allow free movement of traffic. This avoids unnecessary delays, and gives the troops more rest.

185. Every opportunity must be seized to attend to the maintenance of vehicles. Local workshops, garages, and machine shops must be found and allotted to the repair services. In the absence of local workshops, the repair services must be allotted places both suitable for their work and easy of access.
