The base is a geographically small, defendable area. It has a defined perimeter and set access
controls. The base commander is the unit commander or senior unit commander if more than one unit
is present in the base. The base is the focal point for base defense planning and training. It has to
defend itself against Level I attacks. In case of Levels II and III attacks, the base engages enemy
forces. It delays them until reinforcing MP or a tactical combat force (possibly host nation forces)
arrives to assist in defeating the incursion. Each base will establish a base defense operations center
(BDOC) to plan, coordinate, and supervise base defense operations. The position of the base will be
determined by the G3, support commander, and the RAOC/RTOC.
When possible, the base should be situated and configured to take advantage of natural and man-
made terrain features. The area to be defended may vary. It could be high ground with good
observation and fields of fire or a highly congested area with buildings or jungle, obscuring observation
and limiting fields of fire. Missions (CS, CSS) and security are involved in the final selection of a base
site. They include:
Cover and concealment.
Security and defensive capabilities.
Each of these is discussed below.
Dispersion. Base troops and facilities must be dispersed. This will reduce their vulnerability against
enemy artillery, nuclear, or chemical attacks. However, they must be close enough to provide mutual
support and protection against enemy ground attacks. Therefore, a compromise must be reached
between the conflicting requirements of dispersion and mass.
Cover and concealment. The area should afford good cover, camouflage, and concealment to enhance
the base's survivability.
Internal accessibility. A suitable internal road or trail for large trucks and vans going to all parts of the
support area is the type of a base site with good internal accessibility.
External accessibility. Nearness to the main supply route (MSR) with good routes into and out of the
proposed area is a site with good external accessibility. Alternate routes between the MSR and the
motor park are also important to facilitate two-way traffic. This reduces the chance of a tree blowdown
or rubble blocking entry and exits. Alternative routes also help in the execution of an evacuation plan if
