US Marine Corps Counterintelligence
This Marine Corps Doctrinal Publications, Intelligence, and Marine Corps Warfighting Publication, Intelligence Operations, provide the doctrine and higher order tactics, techniques, and procedures for intelligence operations. The Marine–Corps Counterintelligence Publication complements and expands on this information by detailing doctrine, tactics, techniques, and procedures for the conduct of counterintelligence (CI) operations in support of the Marine airground task force (MAGTF). The primary target audience of this publication is intelligence personnel responsible for the planning and execution of CI operations.
The principal objective of CI (counterintelligence) is to assist with protecting friendly forces. CI is the intelligence function concerned with identifying and counteracting the threat posed by hostile intelligence capabilities and by organizations or individuals engaged in espionage, sabotage, subversion or terrorism. CI enhances command security by denying an adversary information that might be used to conduct effective operations against friendly forces and to protect the command by identifying and neutralizing espionage, sabotage, subversion or terrorism efforts. CI provides critical intelligence support to command force protection efforts by helping identify potential threats, threat capabilities, and planned intentions to friendly operations while helping deceive the adversary as to friendly capabilities, vulnerabilities, and intentions. Physical security reduces vulnerability. Operations security reduces exposure. Combating terrorism makes us a less lucrative target. CI increases uncertainty for the enemy, thereby making a significant contribution to the success of friendly operations. CI also identifies friendly vulnerabilities, evaluates security measures, and assists with implementing appropriate security plans.
The integration of intelligence, CI, and operations culminates in a cohesive unit force protection program.
