3-52. Within large echelon support areas, controlling commanders may designate base clusters for mutual protection and mission command. Within a support area, a designated unit such as a BCT or maneuver enhancement brigade provides area security, terrain management, movement control, mobility support, clearance of fires, and required tactical combat forces. Operational area security operations focus on the protected force, base, base camp, route, or area. This allows sustainment units to focus on their primary function. Sustainment commanders and planners must constantly coordinate with supported operational staffs to synchronize sustainment operations to include all activities of the base camp life cycle and the basing strategy. See ATP 3-37.10 for more information on base camps.
