Which mission is NOT included in the primary missions of a sustainment brigade?

The primary missions of a sustainment brigade focus on various aspects of logistics to ensure that forces are well supplied and sustained throughout their operations. Among these missions, theater opening, distribution, and closing are vital functions that align with the overarching goals of a sustainment brigade.

Theater opening involves the initial setup of logistics capabilities within an operational area, ensuring that forces can begin operations effectively. Theater distribution focuses on delivering supplies and support across the operational area, which is crucial for maintaining combat effectiveness. Theater closing pertains to the orderly withdrawal of forces and their associated logistics support when operations conclude, ensuring a smooth transition out of the theater.

In contrast, theater logistics, while a broad term that encompasses many logistical functions including aspects of supply, maintenance, and transportation, is not as precisely defined as the other missions listed. Instead, it represents an overarching concept rather than a distinct mission. Consequently, it does not align with the explicitly defined primary missions of a sustainment brigade in the same way that the other options do. Understanding these distinctions helps clarify the specific roles and missions of sustainment brigades in the context of Large-Scale Combat Operations.
