Role and responsibilities

Like the Assistant Secretary of Defense for International Security Affairs, the ASD is responsible for oversight of security cooperation programs and foreign military sales programs within the regions under its supervision. The ASD also works closely with the United States Indo-Pacific Command, United States Central Command, and the Asia-Pacific Center for Security Studies. Finally, the ASD represents the USD and the Secretary of Defense in interagency policy deliberations and international negotiations related to the Asia-Pacific region. The Office of the ASD is an entity of the Office of the Secretary of Defense.

Structure

This office was created in 2007. It is composed of at least six country/sub-regional desks, each manned by a Senior Country Director. Most desks are also supported by an Assistant Country Director or group of Country Directors. As of February 2011, the desks listed on the APSA website included:
However, this list must be incomplete, since the office also has oversight of programs in Central Asia, Afghanistan and Pakistan, as well as India and other Asian nations.
Depending on their areas of coverage, the country/sub-regional desks report to four different Deputy Assistant Secretaries:
DASDs are appointed by the Secretary of Defense. Some are appointed from civilian life, while others are career defense officials. Once at the DASD level, the latter are considered a part of the DoD Senior Executive Service.
The ASD is also supported by a Principal Deputy, or PDASD, who helps oversee the three DASDs and the office's country/sub-regional desks.
