  DEVELOPING RAPPORT
  8-9. The basis of rapport is source confidence in the HUMINT collector,
  which leads to a willingness to cooperate. Rapport does not necessarily mean
  a friendly relationship, although that may be the case. It means an
  establishment of a relationship in which the HUMINT collector presents a
  realistic persona designed to evoke cooperation from the source. The source
  responds with relevant, truthful information. Rapport is established during
  the approach and must be maintained throughout the questioning of the
  source. If the HUMINT collector has established good rapport initially and
  then abandons the effort, the source would rightfully begin to question the
  HUMINT collector’s sincerity and may cease answering questions.
  BUILDING RAPPORT
  8-10. Building rapport is an integral part of the approach phase. The
  establishment of rapport begins when the HUMINT collector first encounters
  the source. Depending on the situation, the HUMINT collector may introduce
  himself to the source. In debriefing and liaison operations, this will normally
  be the collector’s true name and affiliation. In elicitation, the requirement
  and type of introduction depends on the operation. In interrogation
  operations, the HUMINT collector normally will not introduce himself unless
  he is laying the groundwork for an approach. If he does introduce himself,
  normally he will adopt a duty position and rank supportive of the approach
  strategy selected during the planning and preparation phase. The HUMINT
  collector must select a rank and duty position that is believable based on the
  HUMINT collector’s age, appearance, and experience. A HUMINT collector
  may, according to international law, use ruses of war to build rapport with
  interrogation sources, and this may include posing or “passing himself off” as
  someone other than a military interrogator. However, the collector must not
  pose as—
  • A doctor, medic, or any other type of medical personnel.
  • Any member of the International Committee of the Red Cross (ICRC)
  or its affiliates. Such a ruse is a violation of US treaty obligations.
  • A chaplain or clergyman.
  • A journalist.
  • A member of the US Congress.
  8-11. The HUMINT collector should seek advice from his SJA concerning
  representing himself as holding any other sensitive position.
  8-12. A good source assessment is the basis for the approach and vital to the
  success of the collection effort. The HUMINT collector continually assesses
  the source to see if the approaches—and later the questioning techniques—
  chosen in the planning and preparation phase will indeed work. Approaches
  chosen in planning and preparation are tentative and based on the limited
  information available from documents, guards, and personal observation.
  This may lead the HUMINT collector to select approaches that may be totally
  incorrect for obtaining this source's willing cooperation. Thus, careful
  assessment of the source is critical to avoid wasting valuable time in the
  approach phase. Whether the HUMINT collector is using reasoned argument
