A transfer between two DON accounts is referred to as what type of transfer?

The term used to describe a transfer between two Department of the Navy (DON) accounts is indeed "Account to Account." This designation emphasizes that the transaction occurs within the same organizational framework or system, specifically involving different accounts under the DON.

When discussing financial transfers, it's important to recognize the distinctions between the various types of transfers. An "Intra-Service" transfer typically refers to the exchange of resources or assets within a single service branch, such as the Navy or Marine Corps, whereas "Inter-Service" would involve transfers between different branches of the military. "External" transfers generally indicate transactions involving parties outside the organization or system in question. Therefore, when referring specifically to the process of moving resources between two accounts under the same DON, "Account to Account" is the most accurate terminology.
