The DNI has designated the USD(I) as his Director of Defense Intelligence (DDI).

• A. The USD(I)
• B. The Deputy Director DNI
• C. The Director of DIA
• D. The Assistant Secretary of Defense for Intelligence

Answer: (A)

In the DoD intelligence structure, the Director of National Intelligence designates the Director of Defense Intelligence, who leads the Defense Intelligence Enterprise and reports to the DNI. When the DNI designates the Under Secretary of Defense for Intelligence as the Director of Defense Intelligence, that person becomes the DDI and effectively heads DIA. The DDI is the senior defense intelligence official responsible for integrating DoD intelligence and advising the DNI on defense intelligence matters. The Deputy Director DNI is a separate role serving as the DNI’s deputy, not the DDI. The Director of DIA is the office the DDI leads, not the person designated as DDI. The Assistant Secretary of Defense for Intelligence is a different civilian position within the department. Therefore, the correct designation is the Under Secretary of Defense for Intelligence.
