  network, information systems, and information management processes that enable command and control.
  Signal soldiers implementing the network and information systems and performing their staff tasks enable
  secure communications and situational awareness throughout their operational area. This enables the
  commander’s exercise of command and control in support of unified land operations. See introductory
  figure-2.
  Introductory figure-2. The command and control system
  By providing the network and conducting information management tasks to support the knowledge
  management process in the command and control system, signal formations and staff elements enable secure
  communications and situational awareness throughout their areas of operations. Information management
  processes enable knowledge management and allow commanders to control their formations and synchronize
  efforts across warfighting functions while conducting unified land operations.
  The Army’s network enables every mission, from training the force to executing tactical tasks to influence
  the operational environment in large-scale combat operations. The network is the part of the command and
  control system that provides infrastructure for voice, data, and video connectivity to support operations. The
  network disseminates the common operational picture and enables unified action partner integration. With
  modern tactical radio systems able to pass digital information, the network extends as low as the individual
  Soldier on the battlefield.
  FM 6-02 outlines signal doctrine in five chapters with supporting appendixes to address tactics and
  procedures for signal support to Army operations. The techniques to accomplish the signal missions,
  functions, and tasks in this field manual appear in signal-specific Army techniques publications.
  This revision to FM 6-02 adopts new doctrinal terms, force structure, and tactics implemented since the most
  recent update. This manual supersedes FM 6-02, dated 22 January 2014. FM 6-02 chapters include—
  Chapter 1 section I discusses the operational environment, information environment, and threat as they relate
  to signal support. Section II introduces the fundamental principles of successful signal support to joint and
  Army operations and the core competencies of the Signal Corps. Section III discusses the role of signal forces
  in Army operations.
  Chapter 2 section I discusses signal support to Army operations by echelon—corps and below units with
  organic signal capabilities; units without organic signal capabilities; echelons above corps signal units that
  provide support; and signal support to other Army operations. Section II details the core competencies and
  essential capability of the Signal Corps. Section III discusses individual and collective signal training. Section
  IV discusses the joint and Army networks that enable command and control across the range of military
  operations.
  Chapter 3 section I discusses signal support to Army operations to shape. Section II discusses signal support
  to Army operations to prevent.
  Chapter 4 section I provides an overview of signal support to large-scale combat operations. Section II
  discusses signal support to large-scale defensive operations. Section III discusses signal support to large-
  scale offensive operations.
  Chapter 5 discusses signal support to Army operations to consolidate gains.
  Appendix A discusses tactics and procedures for operations in a contested environment. It outlines the
  procedures when communications systems and networks come under enemy electronic or cyberspace attack.
