text: Security Operations
  area security in major combat operations and stability tasks. Examples of high-value assets to be secured in
  major combat operations include the following:
  * Major power-generation facilities (power plants and dams).
  * Airports, seaports, and other centers for mass transit.
  * Industrial complexes.
  * Cities.
  * Dislocated civilian camps.
  5-143. High-value assets to be secured in stability tasks include the following:
  * Government officials and political and military leaders.
  * Government facilities.
  * High-value detainees.
  * Pipelines and relay stations.
  5-144. Considerations the security force should address when it tasks subordinate elements to secure
  high-value assets include the following:
  * Internet protocol address, frequencies, location, and linkup point of the high-value asset.
  * Route used in reaching the high-value asset, and the composition and disposition of enemy forces
  that can influence the route.
  * Mission and movement or positioning plan of the high-value asset.
  * How easily the threat may detect and target the high-value asset with indirect fire. The security
  force should consider its own survivability and maintain adequate standoff from the high-value asset.
  * Duration of the mission and sustainment considerations.
  * Other friendly or neutral forces in the area and their task and purpose.
  * Triggers for change of mission from security to reconnaissance, offensive, or defensive actions. Is
  there an implied reserve mission?
  * Ability of the security force to maintain communications with higher headquarters.
  * Locations used by enemy personnel serving as forward observers for enemy indirect fire systems.
  SECTION IV – TRANSITION PLANNING
  5-145. The transition from offensive to defensive operations or vice versa consistently occurs during
  large-scale combat operations. Cavalry units perform battle handovers by conducting a passage of lines
  (forward or rearward), a transition using a relief in place, or a change of mission. Passage of lines and relief
  in place are enabling operations found in ADP 3-90.
  5-146. Cavalry units are consistently transitioning from reconnaissance and security operations or vice
  versa; therefore, planning for transitions begins early in the operations process during the development of the
  concept of operations and scheme of maneuver in which decision points are identified for when to execute
  those necessary transitions. The reconnaissance and security efforts by the Cavalry unit answer information
  requirements that enable the BCT commander and staff to develop transition decision points or refine the
  same decision points if the Cavalry unit has to transition earlier or later than originally planned based on
  effects from enemy or terrain. The decision points that drive the transition of the Cavalry unit must be
  understood at each echelon to ensure the BCT maintains tempo as transitions occur.
  BATTLE HANDOVER
  5-147. A battle handover is a coordinated operation between two units that transfer responsibility for
  fighting an enemy force from one unit to the other. During defensive operations, the battle handover is usually
  coordinated in advance so that when ordered to occur, the operation requires minimum coordination. In the
  offense, it is often initiated by a fragmentary order based on the situation at hand. Clear standard operating
  procedure (SOP) allows units to quickly establish the necessary coordination to preclude a loss of momentum
  in the attack. A battle handover is typically associated with the conduct of passage of lines (forward or
  rearward).
