Storage Magazine Categories
The storage categories of munitions are given in AR 190-11. An extract of the relevant part of AR 190-11 is
included in the Appendix at the end of this subcourse booklet.
Category I and Category II. Bulk storage areas are depot activities, prestock points, and ASPs at which
bulk quantities of missiles, rockets, ammunition, and explosives are stored. These items are usually stored in their
original containers. The magazines considered acceptable for storage are listed in DOD 6055.9-STD as
implemented by AR 385-64. Storage structures acceptable for storage of category I and category II ammunition
and explosives are the earth-covered magazines and igloos listed in paragraphs 5-2a and 5-2b of AR 190-11 and
DOD 6055.0-STD. Commanders may permit the storage of missiles, rockets, ammunition, or explosives in other
types of structures if comparable security is provided and if all other requirements are met.
Unless continuously manned or under constant surveillance, category I and category II storage facilities must be
protected by intrusion detection systems (IDSs). MACOMs must program the installation of IDSs for category I
and category II storage facilities at the earliest practicable time.
Storage facilities must be periodically checked by a security patrol as dictated by any threats and by the
vulnerability of the facility. Checks are conducted on an irregular basis during nonduty hours. When the facility
is protected by an IDS, the intervals between checks may not exceed 24 hours. Pending installation of an IDS, or
in the case of an IDS failure, the intervals between checks for facilities storing category I items may not exceed
one hour. The intervals between checks may not exceed two hours for facilities storing category II items.
Category III. Ammunition and explosives listed under category III are stored in structures constructed
according to the applicable guidance. Structures without alarms must be checked by a security patrol at irregular
intervals not to exceed 24 hours. Patrol checks are not required for IDS-protected facilities. New IDSs may not
be programmed for category III storage facilities unless they are determined necessary based on an assessment of
local threats, vulnerabilities, and cost effectiveness.
