What is the Military Postal Service an extension of?

The Military Postal Service is an extension of the United States Postal Service. This system allows military members to send and receive mail while stationed away from their normal addresses, especially during deployments and assignments abroad. The Military Postal Service operates under the regulations and guidelines of the United States Postal Service, ensuring that military personnel have access to the same postal services that civilians enjoy, albeit with some adaptations for the unique needs of service members.

This system is crucial for maintaining communication with family and friends, which is a significant factor in the morale and well-being of military personnel. It is supported by infrastructure that includes military post offices and select civilian postal facilities that handle military mail.

The other options, such as the Department of Defense, Military Transportation, and Defense Logistics Agency, are related entities but do not have the direct postal service function that the United States Postal Service provides in this context. The Military Postal Service relies on the robust framework and existing resources of the U.S. Postal Service to fulfill its mission for military personnel.
