This not only includes the oversight of supply chain logistics but also involves planning and coordinating fuel distribution to ensure it aligns with the units' operational needs and timelines.

In contrast, while determining fuel requirements for local units is an important aspect of sustainment, it typically falls under the responsibilities of smaller operational elements rather than the TSC, which focuses on broader theater-level management. Managing fuel capabilities at the brigade level is more localized and specific, emphasizing a narrower scope than the TSC's theater-wide responsibilities. Serving as the tactical commander in operations pertains to command roles and responsibilities that are distinct from the supply chain and logistics functions performed by the TSC. Thus, executing theater management of fuel is the most accurate representation of the TSC's
