It sometimes happens that there is an absence of secure facilities mentioned above. If so, unit
commanders may grant special authority. They may authorize sensitive items, other than weapons and
ammunition, to be stored in arms storage facilities.
(1) All areas in which AA&E are stored will be designated and posted as a restricted area. This
will be done in accordance with AR 190-13. Posting will include fire control measures and symbols. In
overseas commands, the areas must be posted in English and the language of the host country.
(2) Signs will be displayed on all arms storage facilities using IDSs. These signs will
prominently announce the presence of such systems. Signs will be metal, as described at Appendix D,
and they will be affixed at eye level, wherever possible. They will be placed on the exterior of each wall
which contains an entrance to the arms storage room, vault, building, or magazine.
f. Fences and Associated Barriers. Certain areas will be enclosed with fences which meet the
requirements listed below. These areas are arms storage buildings and outside areas where aircraft or
vehicles are parked with weapons aboard.
(1) Fabric. Fence fabric shall be of chain link (galvanized, aluminized, or plastic-coated woven
steel) 2 inch square mesh, 9-gauge diameter wire. Fencing used in Europe may conform to NATO
Standard Designed Fencing. Specifications for NATO fencing shall be 2.5-3mm gauge, 76mm grid
opening, 2 meter height, and 3.176 meter post separation.
(2) Mounting. Post, bracings and other structure members will be located on the inside of the
fence fabric. Fence Fabric shall be secured to posts and other structural members. Galvanized steel
or aluminum tie-wires equal in gauge will be used to secure the fencing.
(3) Height. The minimum height of the fence shall be 6 feet.
(4) Anchoring. The bottom of the fence fabric will extend to within 2 inches of firm ground. This
will prevent intruders from lifting the fabric to gain access. Sometimes surface stabilization is not
possible. This may be due to loose sand or shifting soils. If so, concrete curbs, sills, or other anchoring
devices, extending below ground level, shall be provided.
(5) Modification to Existing Fencing. Existing Fencing may provide an equivalent or greater
penetration resistance. If so, changes to existing chain link fencing shall not be made to conform to the
(6) Barrier Openings.
(a) A minimum number of vehicular and pedestrian gates shall be established for barriers.
The number should be based on operational
