Who is the senior logistics commander for the BCT?

• A. BSB Commander.
• B. SPO.
• C. S3.
• D. Battalion Commander.

Answer: (A)

In a Brigade Combat Team, logistics for the whole brigade are coordinated under the Brigade Support Battalion. The commander of the BSB has the overall authority for sustainment across the entire BCT, making them the senior logistics commander for the brigade. The Sustainment Planning Officer handles planning and coordination within the sustainment cell, the S3 focuses on operations, and the Battalion Commander leads a maneuver battalion, not the brigade’s logistics system. Therefore, the BSB Commander is the correct choice.
