Requisitions to replace guidance and control units (GCU) are based on which factor?

The basis for requisitions to replace guidance and control units (GCU) is primarily tied to the number of unserviceables returned to the depot or manufacturer. This factor reflects the actual condition of the equipment in the field and informs procurement decisions. When units are deemed unserviceable, it indicates that they can no longer function as intended and therefore must be replaced to maintain operational readiness.

This approach ensures that supply chain management is reactive to the current inventory situation, addressing the need for replacements driven by the equipment's assessed condition rather than relying solely on projections or estimations about future needs or usage rates. The accurate measurement of unserviceable items provides a tangible basis for determining how many new units need to be ordered, ensuring that military operations remain well-equipped and effective.
