What is the primary function of a re-supply during patrolling?

The primary function of a re-supply during patrolling is to ensure that the patrol has adequate resources. This is crucial because patrols operate in potentially hostile conditions where the availability of supplies, such as food, water, ammunition, and other necessary equipment, directly impacts their effectiveness and ability to complete their mission.

Re-supplies are strategically timed to provide units with what they need to sustain operations over time, allowing them to carry out their objectives without having to return to a base for resources. By maintaining adequate supplies, a patrol can remain mobile, flexible, and ready to respond to changing situations in the field. Thus, the successful execution of a patrol's mission often hinges on the efficiency of the re-supply process.
