text: Preface
  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.
  Commanders, staffs, and subordinates ensure their decisions and actions comply with applicable U.S.,
  international, and, in some cases, host-nation laws and regulations. Commanders at all levels ensure their
  Soldiers operate according to the law of war and the rules of engagement. (See FM 27-10.)
  FM 3-55 uses joint terms where applicable. Selected joint and Army terms and definitions appear in both the
  glossary and the text. Terms for which FM 3-55 is the proponent publication (the authority) are marked with an
  asterisk (*) in the glossary. Definitions for which FM 3-55 is the proponent publication are boldfaced in the
  text. For other definitions shown in the text, the term is italicized and the number of the proponent publication
  follows the definition.
  FM 3-55 applies to the Active Army, Army National Guard/Army National Guard of the United States, and
  United States Army Reserve unless otherwise stated.
  The proponent of FM 3-55 is the United States Army Combined Arms Center. The preparing agency is the
