  Fighting for Intelligence
  Fighting for intelligence requires leveraging national to tactical information collection,
  analytical capabilities, and PED capabilities to overcome challenges posed by threats
  within the OE. No one unit or echelon can collect all of the relevant information needed to
  identify and open windows of opportunity to continuously provide commanders and staffs
  situational understanding of the threat, especially during large-scale combat operations.
  Fighting for intelligence requires the G-2/S-2, in coordination with the G-3/S-3, other staff
  members, and the intelligence enterprise, to holistically portray the OE so friendly forces
  can gain and maintain situational understanding, present multiple dilemmas across
  domains, and deliver lethal capabilities.

  Intelligence at and Across Echelons
  SECTION I – OVERVIEW
  7-1. The Army portion of the intelligence enterprise, supported by an overarching Army intelligence
  architecture, facilitates intelligence support across echelons (for example, broadcast dissemination of higher-
  level collection) and at echelon as well as the synchronization of certain aspects of intelligence across
  echelons. However, to really understand Army intelligence support, intelligence professionals must
  understand intelligence support from national to battalion levels. Fundamentally, intelligence products,
  policy, and, in some situations, certain intelligence services flow down from the national level (along with
  partner nations) to joint headquarters and forces to theater army down (through the Army echelons) to the
  battalion level. This perspective provides a basic model. In some situations, intelligence also flows up from
  the tactical level to successive higher echelons—at times up to the national level—because of the unique
  access tactical-level intelligence can sometimes provide.
  7-2. Figure 7-1 on page 7-2 provides a basic illustration of each echelon, including its intelligence staff and
  organic or supporting MI unit, to assist subsequent discussions of intelligence support at and across echelons.
