text: Force Projection Operations Considerations
  C-39. Forward theater intelligence activities greatly contribute to homeland defense. In addition to assessing
  threats in forward theaters, Army intelligence staffs, units, and organizations worldwide have a significant
  role in detecting, deterring, and preventing attacks against the United States. Forward theater intelligence
  staffs, in coordination with intelligence staffs supporting homeland defense, must establish intelligence
  handover lines and other approved control measures and procedures to lessen the possibility of gaps in
  coverage to detect threats against the U.S. homeland.
  C-40. Interorganizational cooperation is critical to homeland defense. The success of interorganizational
  cooperation hinges on timely and accurate information and intelligence for decision making. Information
  sharing environments should include as many essential participants as possible, with the understanding that
  not all can participate in a collaborative environment. When possible, a collaborative intelligence sharing
  environment should be capable of generating and disseminating intelligence, operational information, and
  orders, where needed, in the shortest time possible.
  C-41. Army intelligence units conducting homeland defense should anticipate sharing intelligence with
  Army units during force projection processes. Theater army ACEs and JTF/JFLCC-level joint force
  intelligence operations centers have a critical role in making intelligence assessments available to deploying
  forces. (See ATP 2-91.7 and ADP 3-28.)
  C-42. Intelligence units may conduct analysis of and intelligence collection against peer threats or foreign-
  intelligence-related opportunist threats impacting DOD DSCA missions, and in certain instances, provide
  situational awareness, damage assessments, or incident awareness and assessments according to Secretary of
  Defense authorization and combatant command DSCA-related mission orders. (See ATP 2-91.7.)
  Note. For Army intelligence forces conducting homeland defense and DSCA, intelligence staffs,
  units, and organizations must reference specific intelligence mission and authorities in homeland
  defense related OPORDs and associated Annex B (Intelligence) in order to ensure compliance
  with DOD intelligence activity guidance.
