During warfighter exercises, it had become apparent that division and corps commanders were challenged with mission command of forces in their support areas. The commander of United States Army Forces Command directed commanders to establish a support area command post (SACP) to improve mission command. The Army's new Field Manual (FM) 3-0, Operations (06 OCT 2017), incorporates this guidance by modifying the geographical organization of an area of operations. FM 3-0 scales down the size of the support area and adds a consolidation area. The consolidation area will be assigned to a maneuver brigade or division. This enables the maneuver enhancement brigade (MEB) to perform its traditional mission and focus efforts on operations in the support area. FM 3-0 formalizes the requirement for divisions and corps to establish a SACP (its doctrinal name, which is used throughout this handbook) to assist in controlling operations in the support and consolidation areas.
