The Military Postal Service is an extension of what organization?

The Military Postal Service operates as an extension of the United States Postal Service (USPS). This relationship allows military personnel and their families to access postal services while stationed away from their normal residence, including overseas. The USPS provides the infrastructure and postal regulations, which ensures that service members can send and receive mail, packages, and official correspondence just like civilians do, albeit under specific military guidelines and procedures.

The collaboration between the Military Postal Service and the USPS ensures that military mail is handled efficiently and is a vital part of maintaining communication for service members who may be deployed or stationed far from home. This system supports the unique needs of the military postal system, allowing for secure, reliable, and expedited mail services tailored to military operations.

The other options do not accurately represent the foundational role of the USPS in regards to the Military Postal Service. For example, while the Department of Defense plays a crucial role in military logistics, it does not operate the postal system itself. Similarly, Military Service Command and Federal Postal Authority do not serve as the direct source or operational body for military postal services.
