4.12.4 Auxiliary Guard Positions / Fighting Positions
Many installations desire additional position(s) for security personnel to facilitate a response
to a threat. These positions are normally placed in the response zone to facilitate surveillance
and armed response. This position may be fixed or temporary/portable. The auxiliary
guard position/fighting position may be intermittently or routinely occupied. The facility will
be designed to permit security personnel to respond to any attackers from a protected
position (1). A permanent facility will normally be site-built. Other than openings or
penetrations for weapons, the structure will provide ballistic protection from a medium threat
severity level (UL 752 Level III) in accordance with MILHDBK 1013/10 as a minimum. The
position shall be provided with controls to activate the active vehicle barrier system and
HVAC as required for the environmental conditions.
The location of the auxiliary guard position should also be designed to afford personnel the
ability to assess the threat, initiate alarms, activate the barrier system (if other personnel are
incapacitated), and respond to the attack with force if necessary and authorized. Therefore
the auxiliary guard position shall be located to provide a minimum of four (4) seconds of
reaction time from the time a threat is detected or an alarm is initiated. The threat scenarios
and guidelines for assessing the distance required in order to afford sufficient response time
are discussed in Section 3.3.3. In most cases the auxiliary guard position will be located at or
near the end of the response zone in order to provide sufficient distance for this response.
Location of this facility shall also be coordinated with security personnel to ensure proper line
of fire and safety considerations. If required, the facility may be elevated to facilitate the
observation of incoming traffic and reduce incidental/collateral damage associated with line
of fire considerations.
The finished floor elevation should be 152 mm (6 inches) or more above grade or the
adjacent walkways, unless the facility is located on a raised island. If the facility is on an
island, the minimum finished floor elevation will be the elevation of the island (4). Provide
floors and walkways with anti-skid surfaces. Anti-fatigue mats should be provided at all
security personnel posts to relieve fatigue and discomfort from standing for long periods of
Design walls, doors, windows, and roof of the facilities for typical environmental loading. The
required physical security design features shall be determined in accordance with installation
requirements and existing security engineering references such as MIL-HDBK 1013/1A or TM-
853. Threats that may commonly be considered include forced entry and ballistic attack.
MIL-HDBK 1013/10 specifies, as a minimum, ballistic protection will be provided for a
medium threat severity level. This threat severity level is equivalent to UL/ ANSI/ 752 Level
III (SPSA). This protection will be a consideration in the design and construction of the exterior
envelope including windows, doors, walls, and other equipment. Table 4-3 provides
examples of the wall thickness required for commonly encountered materials to provide an
adequate ballistic resistance from the medium severity threat level.
