  HUMINT in Support of Army Operations
  3-1. Army doctrine for full spectrum operations recognizes four types of
  military operations: offensive, defensive, stability and reconstruction, and
  civil support. Missions in any environment require the Army to conduct or be
  prepared to conduct any combination of these operations. HUMINT assets
  will be called on to provide information in support of all four operations.
  Simultaneous operations, for example elements of a force conducting
  offensive operations while other elements are engaged in stability and
  reconstruction operations, will cause a similar division of the limited
  HUMINT assets based on METT-TC.
  OFFENSIVE OPERATIONS
  3-2. Offensive operations aim at destroying or defeating the enemy. Rapid
  maneuver, constantly changing situations, and a vital need for intelligence
  support at the point of contact influence HUMINT missions during offensive
  operations. The guiding principle to the use of HUMINT in support of
  offensive operations is to minimize the time between when friendly forces
  encounter potential sources (detainees, refugees, and local civilians) and
  when a HUMINT collector screens them.
  3-3. During offensive operations, at echelons corps and below, HCTs
  normally operate in the engaged maneuver brigades’ AOs and are further
  deployed in support of maneuver battalions based on advice from the OMTs.
  These collection assets may be in general support (GS) of the parent brigade
  or in DS of the maneuver battalions, reconnaissance squadrons, and other
  forward-deployed maneuver assets. The HCTs and their supporting control
  structure are deployed in accordance with METT-TC based on three
  principles:
  • The relative importance of that subordinate element’s operations to the
  overall parent unit’s scheme of maneuver and the overall ISR plan.
  • The potential for that subordinate element to capture detainees, media
  and materiel, or to encounter civilians on the battlefield.
  • The criticality of information that could be obtained from those sources
  to the success of the parent unit’s overall OPLANs.
  3-4. HUMINT missions in support of offensive operations include screening
  and interrogating EPWs and other detainees, questioning and debriefing
  civilians in the supported unit’s AO, and conducting DOCEX, limited to
  extracting information of immediate tactical value. EAC assets normally
  support offensive operations through theater interrogation and debriefing
  facility operations and mobile interrogation teams. These facilities are better
  equipped to conduct in-depth interrogations and DOCEX, so it is imperative
