control will include provisions to reject vehicles without penetrating the controlled
perimeter.

Government Vehicle Parking. Limitations on parking near buildings
apply to all vehicles, including official and tactical vehicles, except for emergency
vehicles and for operations support vehicles that are never driven out of restricted
access areas, as established in these standards. Government vehicles other than
those support and emergency vehicles are included in the parking limitations in these
standards because it is assumed that when they are out of restricted access areas they
may be out of the immediate control of their operators, which could make them
susceptible to having explosives placed on or inside of them.
2-4.4
Levels of Protection. The potential levels of protection are described
qualitatively in Tables 2-1 and 2-2. Those descriptions should be used for general
understanding of the goals of the levels of protection. Detailed, quantitative descriptions
of the levels of protection are included in the DoD Security Engineering Facilities Design
Manual.
These standards provide a Low level of protection for billeting, high
occupancy family housing, and primary gathering buildings and a Very Low level of
protection for other inhabited buildings. Greater protection is provided for primary
gathering buildings, billeting, and high occupancy family housing because of the higher
concentration of personnel and the more attractive nature of the target.
If the conventional construction standoff distances are provided, or if
mitigating measures are provided to achieve an equivalent level of protection, and if the
threats are no greater than those indicated in Tables B-1 and D-1, the risk of injuries
and fatalities will be reduced. Threats higher than those envisioned in Tables B-1 and
D-1 will increase the likelihood of injuries and fatalities regardless of the level of
protection. Refer to the DoD Security Engineering Facilities Design Manual for detailed
guidance on levels of protection and how to achieve them for a wide range of threats.
2-4.5
Standoff Distances. The conventional construction standoff distances
identified in Tables B-1 and D-1 were developed to provide survivable structures for a
wide range of conventionally constructed buildings and expeditionary/temporary
structures. These buildings range from tents and wood framed buildings to reinforced
concrete buildings. For a more detailed discussion of this issue, refer to the DoD
Security Engineering Facilities Design Manual.
2-4.5.1
Conventional Construction Standoff Distance. The standoff distances
in the "Conventional Construction Standoff Distance" column in Table B-1 are based on
explosive safety considerations that have been developed based on years of
experience and observation. Those standoff distances may be conservative for heavy
construction such as reinforced concrete or reinforced masonry; however, they may be
just adequate for lighter-weight construction.
2-4.5.2
Minimum Standoff Distance. Because standoff distances from the
"Conventional Construction Standoff Distance" column of Table B-1 may be overly
