18-04 - Mission Command in the Division and Corps Support Area Handbook
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.
