  BCT areas of operations is the responsibility of the appropriate BCT commander. Security of convoys
  transiting previously unassigned areas within the division AO will typically be the responsibility of the
  commander assigned responsibility for the temporary movement corridor designated by the echelon
  headquarters to support that convoy. Planning considerations for the division include—
  * Ensuring proper allocation of combat power to the task.
  * Coordinating combat enablers (fires, attack aviation, electronic warfare assets) for supported units.
  * Allocating information collection assets.
  Movement Corridor
  C-18. A movement corridor may be established to facilitate the movement of a single element or be
  established for a longer period of time to facilitate the movement of a number of elements along a given
  route. The support area commander may establish a movement corridor within the support area along an
  established MSR or a route designated for unit movement. All airspace requirements above the movement
  corridor, such as airspace for aerial recon and fires, must be included in the unit airspace plan to allow the
  establishing unit to conduct effective operations.
  C-19. The unit commander or convoy commander is responsible for a base level of security during
  movement. Most support brigades and functional units have a need for more security that they can organically
  provide during their movement and receive little support from maneuver units to provide additional required
  security. Units owning an AO may provide additional security support to units moving through or that are
  present in their AOs, to include the ability to provide fires. Several tasks and tactics, techniques, and
  procedures can be integrated within an AO to set conditions to help secure individual unit movement, to
  include—
  * Supporting situational understanding.
  * Conducting tactical maneuver (performed by the AO owner or assigned maneuver unit).
  * Conducting route and convoy security operations.
  * Conducting mobility operations.
  * Conducting AT activities.
  * Conducting CBRN operations.
  * Conducting survivability operations.
  * Handing off security responsibility when crossing AO borders or at the nearest secure
  area/facility/base.
  * Integrating fires.
  * Coordinating logistics support.
  * Conducting tactical troop movement.
  * Employing combat patrols.
  * Conducting counterambush actions.
  * Employing obscurants.
  * Providing tactical overwatch.
  C-20. The support area commander task-organizes the enablers required to establish a movement corridor
  and has the staff necessary to establish integrated operations within it. Military police, engineer, logistics,
  EOD, aviation, CBRN, and other forces may establish a combined arms approach to establish a movement
  corridor to provide secure movement of military traffic through vulnerable areas (see figure C-1). Based on
  published movement tables, the combined movement corridor forces will open and maintain a safe passage
  route through uncontrolled terrain. The opening of the route requires a synchronized effort, with each branch
  providing unique movement and mobility skills to the route. The sequence may include engineer route
  clearance and maintenance activities that are integrated with area security implementation along the corridor.
