Field Manual (FM) 3-55, Information Collection, provides the tactics and procedures for information collection and the associated activities of planning requirements and assessing collection, tasking, and directing information collection assets. It also contains the actions taken by the commanders and staffs in planning, preparing, executing, and assessing information collection activities. As the Army fields new formations and equipment with inherent and organic information collection capabilities, it needs a doctrinal foundation to ensure proper integration and use to maximize capabilities. The principal audience for FM 3-55 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as joint task force or multinational headquarters should also refer to applicable joint or multinational doctrine concerning the range of military operations and joint or multinational forces. Trainers and educators throughout the Army will also use this manual.
