What office serves as a liaison between the Department of Defense and the host nation?

• A. Regional Security Office
• B. Office of Public Affairs
• C. Defense Attache Office
• D. Consular Section

Answer: (C)

In diplomatic missions, the Defense Attache Office is the military liaison between the Department of Defense and the host nation. Defense attachés and their staff coordinate defense policy, security cooperation, military-to-military engagement, and reporting on defense matters to the embassy and DoD. This role centers on interacting with the host nation’s armed forces and defense officials to align objectives, programs, and information flows. The other offices have different functions: the Regional Security Office handles embassy security and protection; the Office of Public Affairs manages official communications and media relations; and the Consular Section deals with visas and services for citizens and foreigners. Therefore, the Defense Attache Office best fits the liaison purpose.
