Which term describes a cleared employee designated by the contractor whose principal duty is to transmit classified material to its destination and ensure it remains protected during delivery?

• A. Courier
• B. Messenger
• C. Handler
• D. Escort

Answer: (A)

The role being described is a courier. This position is a cleared employee designated by the contractor whose primary duty is to physically transmit classified material to its destination and maintain its protection during delivery. A courier is specifically tasked with transporting the material under approved security procedures and preserving the chain of custody throughout the journey.

A messenger may move items or messages, but the term doesn’t inherently imply clearance to handle classified material or the formal responsibility for protecting it in transit. A handler usually works with the material inside a secure facility—preparing, processing, or supervising it—not necessarily transporting it. An escort provides protection or accompanies someone during movement, but the primary duty of transporting and safeguarding the material itself lies with the courier.
