Brigade Support Area 18 June 2020 4-5 each base. The commander controlling the BSA does so from the battalion main CP. Security, communications capability, proximity to road network, and other factors influence base placement. A base cluster dispersion complicates enemy detection and targeting. A base cluster spreads sustainment and support assets over a larger geographic area that minimizes the effects of artillery, air, or ground attack. However, a base cluster complicates C2 and perimeter security. Each base requires perimeter defense to allow adequate and mutual protection of other bases. This is accomplished while minimizing the likelihood of striking an adjacent base with small arms fire. Base cluster considerations areβ ξ Coordinating with tenant and transient units/organizations, subordinate base clusters, adjacent base camps, and higher headquarters. ξ Reasonable span of control based on the number and echelon of tenant and transient units or subordinate base clusters. ξ Transporting personnel, equipment, supplies, and waste in the bases and between base camps as part of a base cluster as part of base camp functions, services, and support. A base cluster often lacks a well-defined perimeter or established access points. Although individual bases in the cluster maintain perimeter security, entry, and access control, security requires more personnel than with a single base. Figure 4-2 depicts an example layout of a notional BSA using base clusters to support a BCT instead of a large single-base footprint. Figure 4-2. Example of a notional brigade support area (BSA) layout using a base cluster BRIGADE SUPPORT AREA SECURITY Security operations undertaken by a commander provide early and accurate warning of enemy operations. The unit uses this to react to the enemy and to develop the situation to prevent surprise. In the BSA, units execute local and area security. Area security neutralizes or defeats enemy operations in a specified area. It includes counter- reconnaissance and security of personnel, airfields/landing zones, facilities, MSRs, lines of communication, equipment, and critical points. ATP 4-90
