Appendix C C-4 FM 3-81 09 November 2021 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.
