What does "sustainment" refer to in the context of LSCO?

Sustainment in the context of Large-Scale Combat Operations (LSCO) primarily refers to the logistics and support activities necessary to maintain the operational capability of forces over an extended period. This includes ensuring that units have the supplies, equipment, and maintenance services they need to operate effectively in combat scenarios. Sustainment encompasses not just the supply chain for food, fuel, and ammunition, but also integral services such as maintenance, transportation, and medical support.

This concept is critical in LSCO because military operations often extend over long durations and require a consistent flow of resources to sustain combat operations. Effective sustainment allows units to remain operationally ready and responsive, thus enhancing their effectiveness on the battlefield.

In contrast, planning and executing combat missions relate more to the tactical side of operations rather than the logistical backbone that sustainment provides. Training exercises for military personnel focus on developing skills and readiness, but again, do not directly address the sustainment aspect. Diplomatic negotiations with allies are important for building coalitions and securing support, but they do not pertain to the direct logistical support necessary for the continuous operation of military forces in combat.
