  INTERROGATION
  1-20. Interrogation is the systematic effort to procure information to answer
  specific collection requirements by direct and indirect questioning techniques
  of a person who is in the custody of the forces conducting the questioning.
  Some examples of interrogation sources include EPWs and other detainees.
  Interrogation sources range from totally cooperative to highly antagonistic.
  Interrogations may be conducted at all echelons in all operational
  environments. Detainee interrogation operations conducted at a Military
  Police (MP) facility, coalition-operated facility, or other agency-operated
  collection facility are more robust and require greater planning, but have
  greater logistical support. Interrogations may only be conducted by personnel
  trained and certified in the interrogation methodology, including personnel
  in MOSs 97E, 351M (351E), or select others as may be approved by DOD
  policy. Interrogations are always to be conducted in accordance with the Law
  of War, regardless of the echelon or operational environment in which the
  HUMINT collector is operating.
  DEBRIEFING
  1-21. Debriefing is the process of questioning cooperating human sources to
  satisfy intelligence requirements, consistent with applicable law. The source
  usually is not in custody and usually is willing to cooperate. Debriefing may
  be conducted at all echelons and in all operational environments. The
  primary categories of sources for debriefing are refugees, émigrés, DPs, and
  local civilians; and friendly forces.
  • Refugees, Émigrés, DPs, and Local Civilians Debriefing
  Operations. Refugee, émigré, and DP debriefing operations are the
  process of questioning cooperating refugees and émigrés to satisfy
  intelligence requirements. The refugee may or may not be in custody,
  and a refugee or émigré’s willingness to cooperate need not be
  immediate or constant. Refugee debriefings are usually conducted at
  refugee collection points or checkpoints and may be conducted in
  coordination with civil affairs (CA) or MP operations. Local civilian
  debriefing operations are the process of questioning cooperating local
  civilians to satisfy intelligence requirements. As with refugees and
  émigrés, the local civilians being debriefed may or may not be in
  custody and the civilian’s willingness to cooperate may not be
  immediate or constant. Debriefing operations must be conducted
  consistent with applicable law and policy. Applicable law and policy
  include US law; the law of war; relevant international law; relevant
  directives including DOD Directive 3115.09, “DOD Intelligence
  Interrogations, Detainee Debriefings, and Tactical Questioning”; DOD
  Directive 2310.1E, “The Department of Defense Detainee Program”;
  DOD instructions; and military execute orders including FRAGOs.
  • Friendly Force Debriefing Operations. Friendly force debriefing
  operations are the systematic debriefing of US forces to answer
