Which core sustainment function enables the force to maintain operations over extended periods?

The core sustainment function that enables the force to maintain operations over extended periods is logistics. Logistics encompasses a range of activities essential for supporting military operations, including the management of supply chains, transportation, maintenance, and distribution of resources. This function ensures that personnel have the necessary supplies, equipment, and support services readily available to sustain operations in various environments, particularly in prolonged engagements.

By effectively managing the flow of resources and ensuring that units are adequately supplied and maintained, logistics supports operational readiness and flexibility. This allows military forces to adapt to changing conditions on the battlefield, respond to emerging challenges, and continue operations without unnecessary delays or interruptions. Therefore, logistics is fundamental to maintaining the capability to execute missions over extended timelines.
