What markings must be used on a multi-pack for an FMS shipment containing Shelf-Life items?

The choice highlighting the markings "Multi-Pack" and "Contains Shelf-Life Items" is correct because it directly addresses the labeling requirements specific to Foreign Military Sales (FMS) shipments involving shelf-life items.

Marking a multi-pack as "Multi-Pack" is essential as it informs handlers and recipients that the package contains multiple items, which may require special attention during transportation and storage. The addition of "Contains Shelf-Life Items" alerts all parties involved that the items within have a limited period of usability, thus necessitating careful handling to ensure they remain within their effective dates. This is crucial for maintaining the quality and safety of the items and ensuring compliance with regulations regarding shelf-life management.

Proper labeling not only helps in tracking and inventory management but also plays a vital role in the overall integrity of the supply chain for shelf-life-sensitive products, particularly in military logistics where timely use is critical.
