Displacement of the BSA is driven by which factors?

• A. The forward movement of the BCT battalions and BCT commander's movement of the BCT rear boundary
• B. The color of the vehicles
• C. The weather only
• D. The location of training centers

Answer: (A)

The displacement of the BSA follows the maneuver of the brigade and how the brigade commander adjusts its boundaries. As the BCT battalions move forward, the BSA must shift to stay with the advancing front so logistics, security, and command and control remain within reach. At the same time, the BCT commander moves the rear boundary forward to keep the BSA properly aligned with the current operational area and prevent gaps or misalignment in support and protection. These two factors—forward movement of the battalions and the commander’s adjustment of the rear boundary—drive where the BSA relocates.

Color of vehicles, weather, or training-center locations do not determine BSA displacement.
