text: Preface
  This publication is the Army's field manual for fire support and field artillery operations. It provides
  principles and functions for fire support elements and field artillery units conducting operations in a
  multidomain environment. It establishes the basis for understanding fire support and field artillery as critical
  components of the fires warfighting function tasks. FM 3-09 establishes the core competencies, functions,
  characteristics, and principles of fire support and field artillery.
  To comprehend the doctrine contained in FM 3-09, readers must understand the fundamentals of large-scale
  combat operations and multidomain operations described in ADP 3-0 and FM 3-0. They must understand the
  language of tactics and the fundamentals of the offense and defense, and echelons above brigade described
  in FM 3-90 and FM 3-94. Users of FM 3-09 should also understand the fundamentals of stability operations
  described in ADP 3-07 and the functions and principles of intelligence and sustainment found in FM 2-0 and
  FM 4-0.
  Army leaders must understand joint doctrine and use it when communicating and coordinating directly with
  the joint force. JP 3-0 establishes the baseline operations doctrine for the joint force.
  The principal audience for FM 3-09 is all commanders and their staffs. This publication is intended to provide
  guidance for echelons above brigade for the planning, preparing, execution, and assessment of fire support
  and the employment of field artillery in all operations. Trainers and educators throughout the Army will also
  use this manual. This manual should be studied by those members of the combined arms team or other
  services who are responsible for the delivery of fires in support of large-scale combat operations.
  Commanders, staffs, and subordinates ensure that their decisions and actions comply with all applicable
  United States, international, and host-nation laws and regulations, and all applicable international treaties and
  agreements. Commanders at all levels ensure that their Soldiers operate in accordance with the law of armed
  conflict and applicable rules of engagement. (See FM 6-27 for more information on the law of war.) They
  also adhere to the Army Ethic as described in ADP 6-22.
  FM 3-09 implements North Atlantic Treaty Organization (NATO) standardization agreements (STANAG)
  2484 and 3680.
