What classification is assigned to the only authorized shipment for documents of TS class?

The classification assigned to the only authorized shipment for documents of Top Secret (TS) class is DCS, which stands for "Defense Courier Service." This designation is specifically used for transporting the most sensitive documents that require the highest level of security during transit. DCS ensures that Top Secret materials are handled by authorized personnel and transported in a secure manner, minimizing the risk of unauthorized access or loss.

In contrast, the other classifications, such as TSL (Top Secret Limited), CONFIDENTIAL, and UNCLASSIFIED, do not pertain to the authorized shipment of Top Secret documents but rather indicate varying levels of sensitivity and security requirements. For example, the CONFIDENTIAL classification denotes information that, if disclosed, could cause damage to national security, but does not apply to shipments exclusively designated for Top Secret documents.
