(1) Exclusion
area.
This
is
a
restricted
area
containing
the
following:
(a) a security interest of such nature that entry to the area is
the same as having access to such security interests, or (b) a security
interest of such importance that just being in the area is treated as
equivalent to (a) above.
(2) Limited area.
This is a restricted area having a security
interest.
In this area uncontrolled movement will permit access.
Within
this area, use escorts and other internal controls.
Persons who have a
legitimate reason for entering a limited area may, but they can do so only if
provided adequate restrictions and controls. These measures usually consist
of escorts and other physical safeguards.
(3) Controlled area.
This is an area usually across from or
surrounding limited or exclusion areas.
Entry to the controlled area is
restricted to those with a need for access.
Here movement of authorized
personnel is not necessarily controlled.
Also, entry here does not give
access to the security interest or other matter within the exclusion or
limited areas.
The controlled area is provided for administrative control
and safety. It is a buffer zone for depth in security for the exclusion or
limited areas.
The degree of control movement within this area will be
prescribed by the appropriate CO.
e. A post may have varying degrees of security designation. Or it may
have none at all.
It may be entirely a restricted area; it may have no
further
degree
of
restrictions
or
controls.
It
may
further
be
administratively
classified,
in
whole
or
in
portions.
Further
classifications were covered in the preceding material.
These were an
exclusion area, a limited area, or a controlled area.

Clear Zone.
The effectiveness of security observation, installation
perimeter barriers and lighting depends largely on one thing: that is the
quality of the clear zones around the post. Clear zones are maintained on both
sides of the perimeter barrier.
This provides an unobstructed view of the
perimeter.
Clear zones should be kept clear of weeds, rubbish, and other
material. Any of this is capable of hiding a potential intruder. The texture
and color of the clear zone surface should provide as much contrast as possible
to intruders crossing it.
Clearing and maintaining the zone can be very
difficult; it may require bulldozing, burning, and cutting. It is a must to
control vegetation in this zone. A clear zone of 20 feet or more should be
maintained in some areas.
Examples are between the installation perimeter
barriers and exterior structures. This zone should also be kept between the
barriers and parking areas and natural features. When possible, another clear
zone of 50 feet or more should be maintained, between the perimeter barriers
and structures within the protected areas.
Exceptions occur when a building
wall is part of the barrier.
Sometimes the threat of intruders slipping
through the perimeter barrier is great, as for instance, in a theater of
operations.
Clear zones there may be very wide.
This provides maximum
observation and field of fire. In this case, several lines of perimeter
