Which organization provides for the secure transportation and control of qualified material requiring handling by courier?

The Defense Courier Service (DCS) is the organization specifically responsible for the secure transportation and control of classified and sensitive materials that require handling by courier. This service ensures that such materials are packaged, transported, and delivered in a secure manner, adhering to strict security protocols during their journey.

DCS plays a vital role in maintaining the integrity and confidentiality of the materials being transported, often involving high-stakes documents and equipment integral to national security. Its dedicated focus on courier operations distinguishes it from other organizations that may handle logistics, transportation or distribution but do not specialize in the secure courier aspect.

In contrast to the other options, while organizations like the Military Surface Deployment and Distribution Command and the Military Sealift Command handle broader logistics and transportation needs, and the Air Mobility Command may manage airlift operations, none of these provide the same level of security and specialized services in courier operations as the Defense Courier Service does.
