Describe the COMSEC Courier of the COMSEC program.

• A. Maintains encryption keys
• B. Authorized to transport COMSEC
• C. Stores and inventories COMSEC material
• D. Oversees training

Answer: (B)

The main idea is that the COMSEC Courier is the person officially authorized to move COMSEC material from one secure location to another. Their role centers on securely transporting sensitive crypto material, maintaining an unbroken chain of custody, and following strict transport procedures. This includes using approved secure containers, adhering to designated routes, ensuring proper handoffs with proper documentation, and reporting any loss, compromise, or irregularities right away. Other tasks—such as maintaining encryption keys, storing and inventorying COMSEC material, or overseeing training—belong to different roles within the COMSEC program, not the courier. The courier is focused on the physical transport and custody of COMSEC material in transit.
