The following recognition features are common to all supply facilities:
(1) Buildings are often long and rarely more than two stories high.
(2) The internal road network is well developed; railroad spurs may be present.
(3) Parade grounds and recreational areas are not present.
(4) Landscaping and gardening are not apparent.
(5) Open storage piles are visible; often large, and resemble small buildings.
(6) Track activity is visible; numerous vehicles may be present.
(7) Guard towers and controlled gates usually enclose and further protect the
d. Ammunition facilities. The hazards involved in handling and storing explosives
require a storage pattern easily identified on imagery. The most important characteristic
of ammunition storage is dispersal. Other types of supplies may be spread out, but none
so carefully as explosives. This is done to reduce the possibility of sympathetic
explosions, and explosions caused by shock waves from another explosion. Ammunition
storage facilities are usually located away from population centers for safety. At times,
they are located underground in caves.
(1) The second most frequently observed characteristic is an enclosure, usually
more elaborate than at other supply facilities. In many instances, guard towers are visible
at regular intervals and roadblocks are present at the entrances.
(2) Although fuel depots are occasionally revetted, the presence of revetments
in a supply facility is often a positive indication of ammunition storage. Revetments, too,
serve as protection against sympathetic explosions and enemy attack.
(3) The transportation network in an ammunition depot or dump differs
significantly from those for other types of supply. Here the network is designed to give
maximum separation to storage points. Even when two or more spurs run parallel, there is
a wide separation between them. Road nets may consist of simple or complex loops and
often present a neat appearance.
(4) When ammunition is stored underground, the presence of such a facility is
often disclosed by tunnel entrance and track activity in the vicinity of the entrances.
Driveways leading to the entrances are generally visible (Figure 2-13).
