text: Introduction
  Department of Defense Directive 5100.01 charges the Army to “conduct air and missile defense to support
  joint campaigns and assist in achieving air superiority.” FM 3-01 describes the contributions of the ADA,
  the Army’s dedicated AMD component, to the planning, coordination, and execution of AMD operations in
  support of joint and Army forces in large-scale combat operations.
  Air and missile defense is the direct (active and passive) defensive actions to destroy, nullify, or reduce the
  effectiveness of hostile air and ballistic missile threats against friendly forces and assets (JP 3-01). It includes
  actions that may be taken on the land, in the air, at sea, and in cyberspace and space. AMD is a key element
  of the defensive counterair construct for defeating air and missile threats. AMD operations are generally
  integrated with other offensive and defensive counterair missions within the overall counterair framework.
  While this manual addresses aspects of offensive counterair and passive AMD, it focuses on active AMD
  tactics and procedures.
  FM 3-01 addresses today's operational environment which envisions threats to the Army and joint force that
  these forces have not faced in twenty-five years. In this environment, ADA units must adapt and prepare for
  large-scale combat operations in a highly contested air domain. FM 3-01 provides a doctrinal approach for
  ADA forces to fight future conflicts, explaining how the ADA echelons contribute to the four Army strategic
  roles: shape operational environments, prevent conflict, conduct large-scale ground combat, and consolidate
  gains.
  This FM 3-01 version is organized in terms of the ADA echelons, unlike previous versions which were
  presented from the ADA systems’ perspectives. It presents the roles, functions, and foundational principles
  and employment tenets of ADA echelons, from the Army Air and Missile Defense Command (AAMDC) to
  the air defense airspace management (ADAM) cell. It further depicts the ADA echelons in current or near-
  term operations, with respect to their AMD force operation and engagement operation actions, and discusses
  continuing challenges to these operations.
  This version introduces and defines new AMD terms. It also defines older terms that are repeatedly used,
  but never defined, in other doctrinal AMD publications.
  FM 3-01 consists of 12 chapters.
  * Chapter 1 provides an overview of Army AMD. It introduces a new ADA role statement and
  identifies five key ADA essential capabilities. It introduces the AMD foundational principles and
  employment tenets. It summarizes ADA actions in support of joint and unified land operations.
  Chapter 1 reintroduces short-range air defense (SHORAD), a key contributor to the protection of
  maneuvering forces. The chapter concludes with a discussion of the training of ADA Soldiers and
  leaders. Numerous definitions and expanded explanations of terms are presented throughout the
  chapter to facilitate understanding of AMD actions and language which are applicable to all ADA
  echelons.
  * Chapter 2 discusses the Army operations process from an AMD perspective. AMD force
  operations generally consist of planning and preparatory actions required to support engagements
  of air and missile threats. AMD engagement operations consist of all actions to execute and assess
  the engagements.
  * Chapter 3 addresses the operational environment, focusing on air and missile threats, from rockets,
  artillery, and mortars to intercontinental and submarine-launched ballistic missiles, and their
  generic capabilities. It also addresses the challenges that U.S. forces may face from space and
  cyberspace threats.
  * Chapter 4 describes mission command and also command and control (C2) as related to Army
  AMD. It discusses the principles of mission command through the AMD lens. It also presents the
  applicable authorities and C2 elements resident in the conduct of engagements.
