  Signal Support by Army Echelon, Core Competencies,
  Training, and the Army Network
  This chapter discusses Army signal capabilities by echelon, the core competencies of
  the Signal Corps, signal collective training in units, and the Department of Defense
  information network-Army.
  SECTION I – SIGNAL SUPPORT BY ECHELON
  2-1. Deployable signal elements support the Army’s operational needs, whether they are pooled assets or
  organic to a maneuver or support unit. Unique signal units provide strategic communications infrastructure
  or perform specialized missions and functions.
  CORPS AND BELOW ORGANIZATIONS WITH ORGANIC SIGNAL
  ASSETS
  2-2. Combat and combined arms units at echelons corps and below have organic signal capabilities to
  conduct their standard missions without requiring outside signal support. However, augmentation of
  communications capabilities is required for most enabler units, and if the unit’s operational reach expands
  beyond the capabilities of their organic systems.
  2-3. A brigade combat team may have company- or platoon-sized elements operating beyond the reach of
  single-channel radios, or that require more robust network connectivity and services than those provided by
  the brigade’s organic signal capabilities. This becomes a downward-reinforcing mission of the theater tactical
  signal brigade and expeditionary signal battalion. Refer to ATP 6-02.60 for more information about the
  organic network communications capabilities of corps and below units.
  CORPS
  2-4. The corps is the principal headquarters for applying landpower as a component of a campaign (FM
  3-94). The corps integrates landpower into campaigns and serves as the link between the operational and
  tactical levels of war.
  2-5. The organic signal capabilities of the corps support its main and tactical command posts. When the
  corps serves as a joint task force headquarters, as a joint or multinational land component command, or as a
  tactical headquarters commanding multiple divisions, it may require augmentation from other Services or
  pooled signal assets from the theater tactical signal brigade.
  Corps G-6
  2-6. The G-6 is the principal staff officer who advises the commander on all matters related to
  communications in the corps. The G-6 advises the corps commander, staff, and subordinate commanders on
  technical and training issues related to network and information service integration. During split-based
  operations, the G-6 usually aligns with the tactical command post, while the deputy G-6 remains with the
  main command post. The corps G-6 coordinates with G-3 to direct the actions and movements of signal
  elements to support operations through the orders process.
