Example movement corridor C-21. Engineer and military police forces conduct route reconnaissance missions to determine problems along the route. Sustainment forces may then establish temporary holding, maintenance, or rest areas along the corridor as the tactical situation dictates. With the establishment of military police traffic control posts and convoy escorts of critical commodities of supplies and with aviation convoy security in place, the convoys move along the protected route to their final destination. The movement corridor opens and closes for specified periods of time to meet movement table requirements. C-22. This paragraph discusses support to movement beyond the support area commander’s assigned support area by using the technique of movement corridors. There are several techniques that the support area commander may use to support movement beyond its assigned support area. Where an MSR passes from the support area AO through a division-controlled area directly into a BCT AO, the division could designate an AO around the MSR and assign it to the support area commander as part of the support area. The support area commander could create a movement corridor from the support area boundary to the BCT AO. In this case, the support area commander would be responsible for all actions within the movement corridor. The division would provide the required information collection and fires support. The support area commander would coordinate with higher headquarters and the units conducting the movement to provide the required capabilities to support ongoing operations. The support area commander would transfer responsibility for units moving along the corridor to the BCT at their boundary. The BCT could extend the movement corridor within their AO to their brigade support area or to their other boundary if the MSR passes through the AO. The support area commander’s support to movement that does not move on an MSR could also be provided within a movement corridor. A movement corridor that does not use an established MSR may require additional information collection and other forces to set conditions.
