Which type of publication establishes policies and procedures for Washington Headquarters Services?

The Administrative Instruction (AI) is the correct type of publication that establishes policies and procedures for Washington Headquarters Services. AIs are specifically designed to provide direction and information regarding administrative operations and procedures within certain organizations, including defense and military entities. They serve as official documents that outline how tasks should be performed and how standards should be upheld.

In the context of the Washington Headquarters Services, an AI would outline the framework for operational procedures, governance, and protocols necessary to ensure efficient management and administration. AIs are critical because they offer clarity and consistency within the organizational processes.

The other options serve different purposes within the broader scope of documentation. For instance, a Technical Bulletin typically focuses on specific technical subjects and may provide guidance on particular operations or technologies, while DoD Manuals are broader in scope and may cover policies applicable across the Department of Defense rather than being tailored to a specific service or organization. Field Manuals, on the other hand, are usually focused on tactical and operational guidance for military units rather than administrative functions. Each of these publications has its own role and importance, but they do not specifically target the administrative structure and policies of Washington Headquarters Services in the same way an Administrative Instruction does.
