7-49. Corps and division commanders assign responsibility for the support area to a maneuver enhancement brigade (MEB) headquarters. The MEB commander designates bases and base clusters for all units operating within the support area. Within that support area, the MEB commander has TACON of all friendly forces for terrain management, movement control, clearance of fires, and security. Division commanders can also choose to establish a support area command post (SACP) with one of the assistant division commanders to provide better coordination and mission command of the support area units and missions. All units located in support and consolidation areas are responsible for defending themselves against enemy Level I threats. All units in support and consolidation areas also perform information collection within their organic capabilities and report that information to the appropriate headquarters.
