Structure

This office can trace its roots back to the early days of the modern national security establishment. It was created in 1949, two years after the National Security Act established the Department of Defense.

The ASD (ISA) is supported by seven Deputy Assistant Secretaries (DASDs), each with coverage of a different region or international organization. The DASDs manage "principal directors" who in turn oversee "country directors" with more narrow geographic portfolios:

• Deputy Assistant Secretary of Defense for African Affairs
• Deputy Assistant Secretary of Defense for Europe and NATO
• Deputy Assistant Secretary of Defense for Middle East
• Deputy Assistant Secretary of Defense for Russia, Ukraine, & Eurasia
• Deputy Assistant Secretary of Defense for Western Hemisphere
• Secretary of Defense Representative in the U.S. Mission to NATO
• Secretary of Defense Representative to the Organization for Security and Co-operation in Europe

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 (ISA) is also supported by a Principal Deputy, or PDASD, who helps manage the day-to-day operations.
