covert action by the National Security Act of 1947. President Ronald Reagan issued Executive Order 12333 titled "United States Intelligence Activities" in 1984. This order defined covert action as "special activities," both political and military, that the U.S. government would deny, and granted the exclusive authority to conduct such operations to the CIA.

The CIA must have a presidential finding in order to conduct these activities under the Hughes-Ryan amendment to the 1991 Intelligence Authorization Act.

In an article for ABC News, former Deputy Secretary of Defense and retired CIA paramilitary officer Mick Mulroy explained that the term "covert action" is derived from Presidential Findings authorizing the CIA to conduct specific special activities to support U.S. national security objectives. He advocated for covert actions to be fully incorporated in the U.S. National Security Strategy and the 2018 National Defense Strategy in the form of a Covert Action Annex and for covert actions to be fully funded to operate in support of overall objectives in the form of a Covert Action Fund. Selection and training Special Activities Center has several hundred officers, mostly former members from Tier 1 units like SEAL Team Six and Delta Force, as well as other U.S. Special Operations Forces personnel. The CIA has also recruited individuals from within the agency. The CIA's formal designations for these individuals are paramilitary operations officers and specialized skills officers. Paramilitary operations officers often attend the Clandestine Service Trainee (CST) program, which trains them as clandestine intelligence operatives at an internal paramilitary training course. The primary strengths of SAC paramilitary officers are operational agility, adaptability, and deniability. They often operate
