You have just been assigned as a staff officer in your division's G4 section; which of the following units could command up to seven battalions and synchronize tactical-level sustainment operations?

The Division Sustainment Brigade is the correct answer because it is specifically structured to command multiple battalions, typically up to seven, and is designed to synchronize all aspects of tactical-level sustainment operations within a division. This includes managing logistics, maintenance, and supply chain activities that are essential for ensuring that the fighting units have everything they need to operate effectively on the battlefield.

By overseeing these battalions, the Division Sustainment Brigade can provide comprehensive support, facilitating coordination among various logistics units and ensuring that resources are allocated efficiently and effectively. This command structure allows for better management of sustainment operations, as it centralizes authority and streamlines communication.

In contrast, a Brigade Support Battalion typically functions at a lower level, supporting a single brigade and does not command multiple battalions. A Logistics Support Battalion is generally not tasked with the broader operational scope seen in a Division Sustainment Brigade, and a Forward Support Company operates at an even lower level, supporting specific battalions rather than commanding and synchronizing multiple units. Therefore, the unique role and organizational capabilities of the Division Sustainment Brigade make it the correct choice for the command structure described in the question.
