text: Support Area Responsibilities
  CONTROL MOVEMENT
  4-23. The MEB controls all movement throughout the support area. Units may not move through ground or
  air LOCs without clearance from the MEB. The MEB ensures that movement within the support area does
  not interfere with the corps or division commander’s maneuver or fires execution.
  4-24. The echelon that designates the support area must provide clear guidance on the roles and
  responsibilities for controlling movement. The support area commander designates, maintains, and secures
  movement along the routes within the AO unless the higher headquarters directs otherwise. When a unit
  wants to move within the designated support area, it coordinates with the BDOC or base cluster operations
  center (BCOC). The BDOC or BCOC will coordinate with the MEB commander to obtain movement support
  throughout the support area: intelligence updates, additional security, fires, and final approval. See ATP 4-16
  for additional information on movement control.
  CLEARANCE OF FIRES
  4-25. The MEB commander has the authority to determine surface targets and perform clearance of fires
  within the support area. The MEB integrates fires with security and defense plans (see appendix C) and
  rehearses their employment. Within the support area, the MEB commander may employ any direct- or
  indirect-fire system without further clearance. ADP 3-90 lists three exceptions: munitions effects extend
  beyond the AO, restricted munitions, and restrictive fire support coordination measures. Detailed
  coordination is required of fire support planning and measures to apply fire support to and from adjacent
  division or corps systems according to their targeting and fires priorities. Cross boundary fires should be
  strictly coordinated and, if time allows, thoroughly rehearsed.
  4-26. The MEB must conduct detailed fires planning to allocate resources to be used down to the company
  level while integrating and coordinating fires within the support area. This includes the integration of fire
  support planning and targeting. The MEB commander’s staff will coordinate fires with the higher
  headquarters, base camp, and base cluster staffs. The MEB commander could provide fires if the TCF is task-
  organized with artillery or mortar systems. Much of the time, the support area designated land owner will
  receive fire support from a field artillery battalion. The MEB commander must develop targeting and
  counterfire standing operating procedures (see ATP 3-09.12).
  SECURITY
  4-27. Security is an essential part of support area operations. Security operations are performed by
  commanders to provide early and accurate warning of enemy operations, to provide the forces being protected
  time and maneuver space in which to react to the enemy, and to develop the situation to allow commanders
  to effectively use their protected forces. The ultimate goal of security is to protect the force from surprise and
  reduce the unknowns. The MEB commander must provide security forces to prevent surprise and provide
  time for units within the support area to effectively respond. The MEB commander must inform tenants and
  transients of support area security plans and capabilities. See FM 3-90-2.
  4-28. If properly task-organized, the MEB may perform any required security task within the support area.
  Area security is a security task conducted to protect friendly forces, installations, routes, and actions within
  a specified area. The support area commander is responsible for the security of all units operating with the
  support area. Each unit commander retains responsibility for their unit local security. See ADP 3-37 and FM
  3-90-2.
  4-29. The MEB conducts security tasks and coordinates, synchronizes, and integrates protection capabilities
  (see annex A) to protect friendly forces, installations, routes, and actions within a specified area. The MEB
  provides time and maneuver space in which to react to the enemy and develop the situation. Successful
  security operations depend on properly applying five fundamentals:
  * Provide early and accurate warning.
  * Provide reaction time and maneuver space.
  * Orient on the force, area, or facility.
  * Perform continuous reconnaissance.
  * Maintain enemy contact.
