Which service manages receipt and dispatch services internationally for military installations?

The Aerial Mail Terminal (AMT) is responsible for managing receipt and dispatch services for military installations on an international scale. This service plays a crucial role in the military's logistics and communication framework, as it ensures that mail and packages are efficiently processed and transported to and from military personnel stationed around the world.

The AMT specifically focuses on air mail operations, which is essential for timely delivery across international borders. Military installations often depend on quick and reliable mail services to maintain connections with families, provide necessary supplies, and facilitate communication among deployed service members and their support networks.

Other options like the Primary Postal Service and Global Mail Services may contribute to the overall postal system, but they do not uniquely cater to the specific needs of military installations for international mail transport. The Interstate Postal Authority is focused more on domestic postal issues, further distinguishing the Aerial Mail Terminal's specialized role in maintaining robust international mail services for the military.
