  Joint Intelligence, Surveillance, and Reconnaissance
  The Army conducts operations as part of a joint force. This chapter examines joint
  intelligence, surveillance, and reconnaissance activities as part of unified action. It
  discusses the joint intelligence, surveillance, and reconnaissance concepts, doctrine,
  resources, and planning systems. It then discusses national intelligence, surveillance,
  and reconnaissance resources and guidelines. Lastly, this chapter discusses joint
  intelligence, surveillance, and reconnaissance considerations and organization.
  JOINT ISR AND UNIFIED ACTION
  6-1. Unified action is the synchronization, coordination, and/or integration of the activities of
  governmental and nongovernmental entities with military operations to achieve unity of effort (JP 1). It
  involves the application of all instruments of national power, including actions of other government
  agencies and multinational military and nonmilitary organizations. Combatant and subordinate
  commanders use unified action to integrate and synchronize their operations directly with the activities and
  operations of other military forces and nonmilitary organizations in their area of operations.
  6-2. Army forces in an operational area are exposed to many non-Army participants. Multinational
  formations, host-nation forces, other governmental agencies, contractors, and nongovernmental
  organizations are located in the operational area. Each participant has distinct characteristics, vocabulary,
  and culture, and all can contribute to situational understanding. Commanders, Soldiers, and all who seek to
  gather information gain by working with and leveraging the capabilities of these entities. The Army
  expands the joint intelligence, surveillance, and reconnaissance (ISR) doctrine (see JP 2-01) by defining
  information collection as an activity that focuses on answering the commander’s critical information
  requirements (CCIRs).
  JOINT ISR CONCEPTS
  6-3. Joint ISR is an intelligence function. The J-2 controls joint ISR’s collections systems, which are
  intelligence assets and resources. This is different from Army information collection. Joint ISR does not
  include reconnaissance and surveillance units. Joint usage of reconnaissance and surveillance refers to the
  missions conducted by airborne assets. Integration and interdependence are two key concepts that influence
  how the Army conducts joint ISR in the joint operations area.
  INTEGRATION
  6-4. The Army uses integration to extend the principle of combined arms to operations conducted by two
  or more Service components. The combination of diverse joint force capabilities creates combat power
  more potent than the sum of its parts. This integration does not require joint command at all echelons;
  however, it does require joint interoperability at all echelons.
