21st Century U.S. Military Manuals: U.S. Marine Corps (USMC) Counterintelligence

Part of our value-added professional format series of U.S. military manuals, this U.S. Marine Corps manual details doctrine, tactics, techniques, and procedures for the conduct of counterintelligence (CI) operations in support of the Marine air-ground task force (MAGTF). The primary target audience of this publication is intelligence personnel responsible for the planning and execution of CI operations. Commanders, planners, and other personnel who use the results from CI operations or provide support to them should also read this publication.

Intelligence strives to accomplish two objectives. First, it provides accurate, timely, and relevant knowledge about the enemy (or potential enemy) and the surrounding environment. The primary objective of intelligence is to support decisionmaking by reducing uncertainty about the hostile situation to a reasonable level, recognizing that the fog of war renders anything close to absolute certainty impossible. The second intelligence objective assists in protecting friendly forces through counterintelligence (CI). CI includes active and passive measures intended to deny the enemy valuable information about the friendly situation. CI includes activities related to countering hostile espionage, subversion, and terrorism. CI directly supports force protection operations by helping the commander deny intelligence to the enemy and plan appropriate security measures. The two intelligence objectives demonstrate that intelligence possesses positive—or exploitative—and protective elements. It uncovers conditions that can be exploited and simultaneously provides warning of enemy actions. Thus, intelligence provides the basis for our own actions, both offensive and defensive. Identifying, planning, and implementing MAGTF operations and measures are the main focus of this publication.

CI definition: Information gathered and activities conducted to protect against espionage, other intelligence activities, sabotage, or assassinations conducted by or on behalf of foreign governments or elements thereof, foreign organizations, or foreign persons, or international terrorist activities.
