text: Introduction
  This version of FM 3-09 codifies the multidomain approach to fire support and field artillery operations in
  terms of the combined arms employment of capabilities from multiple domains. A domain is a physically
  defined portion of an operational environment requiring a unique set of warfighting capabilities and skills
  (FM 3-0). The aim of this publication is to establish the functions and principles of fire support planning,
  coordination, execution, and assessment and to describe the fire support system in terms of its major
  components, functions, and required products. This publication describes the fire support system as a
  complete entity and gives equal treatment to all the diverse assets and capabilities that are designated as
  elements of the fire support system.
  The theme of this publication is that the successful delivery of fires depends on the rapid and continuous
  integration and synchronization of all forms of fire support assets with all dynamics of combat power, and
  across all domains for one purpose. This is to place the correct types and volume of fire at the right time and
  on the right targets, across all domains to ensure the success of the supported commander's concept of
  operations.
  This publication provides the foundation for the development of subordinate fire support and field artillery
  doctrine, force design, materiel acquisition, professional education, and individual and unit training. Fire
  support and field artillery techniques manuals go into further detail to explain specific duties for those
  individuals who work within the fire support system. This publication will not describe prototype or non-
  validated systems.
  The source document for FM 3-09 continues to be FM 3-0, Operations. Figure 1 on page xii, shows the logic
  diagram for this publication.
  The major changes from the 2020 FM 3-09 are listed below:
  * Aligns with FM 3-0, on the Army strategic context and joint competition continuum, competition
  below armed conflict, crisis, and armed conflict.
  * Aligns terms and definitions with FM 3-0.
  * Updated the logic chart.
  * Formally recognizes multidomain operations and its tenets.
  * Added tables aligning the tenets and imperatives of operations with fire support and field artillery
  procedures.
  * Updated the difference between the theater fires command and the theater fires element for clarity.
  * Introduces operational fires command.
  * Modified multiple fire support definitions to align with multidomain operations doctrine (see
  introductory Table 1).
  * Adds a large-scale combat battlefield framework figure in chapter 6.
  * Adds a maritime section to the appendix on environmental and terrain considerations.
  * Modified use of maneuver commander to supported commander in appropriate areas to facilitate
  alignment with multidomain doctrine.
  FM 3-09 contains six chapters and four appendices:
  Chapter 1 Covers an overview of the foundations of fire support. Chapter 1 begins by defining fire support,
  describes the characteristics of fire support, adds fire support considerations for the tenets and imperatives of
  operations, defines the fire support system, and fire support functions to include joint and multidomain
  operations.
  Chapter 2 Covers the components of the fire support system, this includes fire support command and control
  elements, target acquisition, and attack/delivery systems.
