Which of the following is a Major Sustainment Operating Force Organization?

A Theater Sustainment Command is designated as a Major Sustainment Operating Force Organization within the Army's sustainment framework. This command is crucial because it provides logistical support at the theater level, ensuring that all necessary supplies, equipment, and personnel are available to meet operational requirements. The Theater Sustainment Command plays a pivotal role in planning, coordinating, and executing sustainment operations across an area of operation, effectively integrating supply chain management and logistics into the broader operational plan.

The other options, while related to sustainment in some capacity, do not represent Major Sustainment Operating Force Organizations. For instance, a Logistics Support Division typically functions under a larger command rather than operating independently at the theater level. Similarly, an Operations Planning Center focuses on the planning aspect of operations rather than on sustainment logistics. The Sustainable Energy Program is a specialized initiative that doesn't fall under the major command structure critical for large-scale logistical operations.
