What security clearance must air-terminal personnel have to receipt classified shipments?

Air-terminal personnel must have a security clearance equal to the highest classification of the affected shipment in order to properly receipt classified shipments. This ensures that all personnel involved have the necessary access to handle sensitive information appropriately. Handling classified shipments requires a robust understanding of the information's security implications, as well as the legal and procedural obligations tied to safeguarding such material.

Having a clearance that matches or exceeds the classification level of the shipments ensures that the personnel are not only authorized but also trained to manage risks associated with the transport and handling of classified data. This level of scrutiny is crucial in maintaining national security standards and ensuring that sensitive information does not fall into unauthorized hands.

In contrast, the other options suggest either a limited clearance or no clearance, which would compromise the security protocols established for classified materials.
