When is it appropriate to implement advice code 2C for an item?

In the context of MILSTRIP procedures, advice code 2C is used to communicate specific preferences regarding the fulfillment of supply requisitions. The correct circumstance for implementing advice code 2C is when full shipment is essential and backorders are not acceptable. This code indicates that the requester requires the complete quantity of the item immediately and should not have any non-critical backorders on the item.

By utilizing this advice code, it highlights the importance of timely and complete delivery of the requested item, allowing the supply process to prioritize these shipments appropriately. This ensures that all necessary resources are directed toward fulfilling the entire request at once, rather than allowing for partial shipments that would result in backorders.

The other options do not align with the intent of advice code 2C. For instance, allowing unlimited backorders signals a different requirement (typically more flexibility), and acknowledging that substitutions may delay shipment indicates a willingness to accept alternatives rather than insisting on the original order in full. Lastly, stating that immediate fulfillment is not critical does not convey the urgency implied by advice code 2C, which specifically emphasizes the need for completeness in the shipment.
