Information Collection (FM 3-55)

This FM, "Information Collection," provides essential and enduring doctrine for Army forces conducting information collection activities. This FM aligns information collection with current Army doctrine. The modular force structure with the brigade combat team as the centerpiece of the deployed force also moves many information collection assets to lower echelons. The latter is a major shift from previous ways of operating. This manual covers the principles and fundamental considerations for information collection planning and execution in operations. Although it recognizes and discusses the impact of systems that support information collection activities, this manual emphasizes fundamentals and concepts rather than equipment or systems. The doctrine contained herein is intended to be broad enough to apply to all operational themes-from a peacetime military engagement to a major combat operation-and applicable at battalion through corps echelons deployed in an area of operations, although each organization employs tactics, techniques, and procedures appropriate to its level. This manual is designed for officers and Soldiers assigned to units that direct or conduct information collection activities as well as commanders and staffs of corps, division, brigade combat teams, support brigades, and battalions. It applies to the Active Army, the Army National Guard, Army National Guard of the United States, and the United States Army Reserve unless otherwise stated; and U.S. Army Training and Doctrine Command institutions and components. This FM forms the foundation for instruction on information collection activities within the Army's educational system.
