What type of transfer occurs between a DON account and the NSA?

The transfer between a Department of the Navy (DON) account and the National Security Agency (NSA) qualifies as an inter-service transfer. This classification is appropriate because it involves transactions between different branches of the U.S. military or government entities. In this case, the DON is one branch, while the NSA represents another, which is not a direct service branch but an agency that supports national defense and intelligence functions.

Understanding this distinction is crucial in COMSEC, where the secure handling and transfer of classified information among different entities must adhere to strict policies and procedures. An inter-service transfer indicates that there are specific protocols in place to ensure that classified information is safeguarded during its transfer between services and agencies, as they may have different operational protocols and security measures.

The other types listed have different meanings. For example, an intra-service transfer refers to movements within the same service branch, while account-to-account and local transfers typically imply more limited, in-house transactions that do not involve inter-agency or inter-service coordination.
