  Allocation of Combat Power
  8-184. Protection of installations or areas of operation (including route and convoy security) by the BCT
  require significant allocation of combat power when a threat beyond organized crime exists. Conducting
  resupply from one base to another is treated as a tactical action and tracked in the BCT main CP current
  operations cell. When the BCT establishes a response force(s), care is taken so that the response force does
  not establish patterns when responding to incidents. Establishment of patterns-same route, same movement
  formation, configuration and order of vehicles, and same response force responding from the same
  base-allows an enemy to ambush the response force at a point of its choosing.
  Note. Dependent on the situation, host-nation security forces are involved as much as possible in
  the performance of the above protection tasks. Host-nation support is important in the variety of
  services and facilities that can support security and protection assets within the BCT’s area of
  operations. Services provided by the host nation can relieve the BCT of the need to provide
  equivalent capabilities thereby reducing the BCT’s sustainment and protection footprint. Key
  criteria in the decision-making process to utilize host-nation support is the trust in host-nation to
  provide the support and that host-nation forces have the technical skills and capabilities to provide
  the desired degree of protection.
  Threat Levels
  8-185. Threats within the BCT’s area security operation are categorized by the three levels of defense
  required to counter them. Any or all threat levels may exist simultaneously in the BCT’s area of operations.
  Emphasis on base defense and security measures may depend on the anticipated threat level. Within the
  BCT’s area of operations all elements protect themselves from Level I threats. This includes medical
  elements although they have reduced defensive capabilities since they can only use their nonmedical
  personnel to provide their own local security. Locating medical elements and other support elements on bases
  with other units mitigate this factor.
  8-186. The BCT commander positions response forces to respond to a Level II threat (enemy force or
  activities that can be defeated when augmented by a response force) in appreciation of time-distance factors
  so that no element is left outside supporting distance from a response force. The commander integrates fire
  support assets into the composition of the response because of the speed at which these assets can react over
  the extensive distances involved in area security operations. Where possible, host-nation security assets
  constitute part of the response to smooth the interactions of these forces with the civilian population.
  Note. A Level III threat is an enemy force or activities beyond the defensive capability of any
  local reserve or response force. The response to a Level III threat is a tactical combat force,
  generally established no lower than division level due to the inability to resource at lower echelons.

  Survivability
  8-187. Precautions should be taken to protect positions, headquarters, support facilities, and
  accommodations including the construction of obstacles, protective bunkers, fighting positions, and shelters.
  BCT subordinate units practice alert procedures and develop drills to occupy positions. Engineer forces
  enable, when available, survivability needs. Units maintain proper camouflage and concealment based on the
  mission variables of METT-TC. Area security forces are vulnerable to personnel security risks from local
  employees and other personnel subject to bribes, threats, or compromise. The threat from local criminal
  elements is a constant threat and protection consideration. The most proactive measure for survivability is
  individual awareness by Soldiers in all circumstances. Soldiers look for things out of place and patterns
  preceding aggression. Commanders and subordinate leaders ensure Soldiers remain alert, do not establish
  routines, and maintain appearance and bearing. (See chapter 7 and ATP 3-37.34 for additional information.)
