Which form should terminating or en route personnel sign upon receipt of classified/security cargo?

The correct answer is that terminating or en route personnel should sign the DD Form 1385, Cargo Manifest, upon receipt of classified/security cargo. This form serves as an official record of the cargo being transported, detailing the types and amounts of classified material being handled. It's critical for ensuring accountability and tracking the movement of sensitive items throughout the supply chain.

When personnel sign the Cargo Manifest, they acknowledge receipt of the cargo, which is essential for maintaining security and ensuring that all classified items are properly documented. This practice helps to mitigate risks associated with the handling of sensitive materials, as it provides a clear chain of custody and assists in identifying any discrepancies or issues that may arise during transportation.

The other forms listed play different roles in logistics and cargo management but are not specifically used for acknowledging the receipt of classified or security cargo in the same manner as the DD Form 1385.
