Who is authorized to sign for and receive classified/security cargo?

The correct choice highlights that only U.S. military or U.S. civilian personnel with proper authorization are allowed to sign for and receive classified or security cargo. This requirement is key for maintaining national security and ensuring that sensitive information or materials do not fall into unauthorized hands.

Classified cargo often contains information that is critical to national defense and security. Therefore, strict protocols are in place governing who can access such materials. Authorization serves as a safeguard, ensuring that only individuals who have been vetted and trained in handling classified information can take possession of it. This minimizes the risk of leaks or misuse.

Other potential choices present scenarios that do not meet the stringent criteria necessary for dealing with classified materials. Allowing any staff member, or even those with merely basic training, to handle these items compromise security protocols and could lead to serious breaches. Military personnel is generally considered more reliable for security matters, but without proper authorization, they too would not qualify. Hence, the emphasis on both military and civilian personnel having the appropriate authorization is essential.
