What is necessary to sustain forces during operations according to logistics principles?

Sustaining forces during operations fundamentally relies on having the ability to deliver the necessary resources consistently and effectively, which is encapsulated in the concept of resupply capability. This encompasses the processes and logistics activities that ensure units receive essential supplies, equipment, and personnel as needed.

Resupply capability ensures that forces can maintain their operational effectiveness over time. Without it, even the most well-prepared units can find themselves unable to perform their mission due to shortages in key supplies, materiel, or maintenance support. The ability to execute timely and efficient resupply operations directly contributes to the overall success of military missions, enabling sustained engagement with the enemy and continuous operational readiness.

While military readiness, force presentation, and operational flexibility are all important aspects of overall logistics and military strategy, they hinge on having a robust resupply capability in place. Without the continuous flow of necessary supplies, readiness and flexibility can quickly diminish, irrespective of personnel training or initial deployments. Therefore, resupply capability is the backbone that supports all military operations and is essential for the sustainment of forces in the field.
