Before a unit occupies a new position, a quartering party must first
make a reconnaissance and lay out a concealed track plan. No vehicle
should enter the new area until this plan has been made and marked
so that drivers can stay on the allotted routes. The quartering party
should be capable of visualizing the appearance of terrain when seen
from the air. A standard track plan is impossible—an individual
solution is required for each installation. Track plan must be laid
out to fit into the terrain pattern as inconspicuously as possible by
taking advantage of existing roads, overhead cover, and shadow-casting
lines which are a normal part of the terrain pattern.
Many factors which affect the character of the track plan must be
considered by the quartering party. Some of these are: the duration
of occupation; time allowed for entering and leaving; size, character,
and mission of occupying unit; known distance from enemy; effect
of climate on visibility; availability of all-weather road surfaces; and
strength of mobile AAA. In addition to laying out a track plan on
the ground itself, track plan should be sketched on either a map
overlay or a sketch of the area. Parking areas are indicated as well
as portions of routes to be patrolled by traffic guides, who are posted
not only to insure that correct routes are taken but that camouflage
discipline is maintained.
The photograph and overlay in figure 12 (1) and (2) illustrate a
typical problem in track planning. Details shown on overlay are—
(1) Approach highway.
(2) Main bivouac entrance road.
(3) Bivouac loop.
(4) Bivouac exit road.
(5) Two-way road linking bivouac and headquarters.
(6) One-way road through vehicle park and headquarters.
