Which agency leads Department of Defense security cooperation efforts?

• A. Defense Security Cooperation Agency
• B. Defense Intelligence Agency
• C. National Security Agency
• D. Central Intelligence Agency

Answer: (A)

Security cooperation for the Department of Defense is led by the Defense Security Cooperation Agency, which plans, policy guides, and executes security cooperation programs across DoD. This includes managing foreign military sales, security assistance, and partner-nation capacity-building, all coordinated with combatant commands and international partners. The other agencies focus on different missions: the Defense Intelligence Agency handles military intelligence, the National Security Agency focuses on signals intelligence and information security, and the Central Intelligence Agency gathers foreign intelligence. None of them directs DoD security cooperation; that role belongs to the DSCA.
