  collection operations must be conducted in accordance 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.
  Additional policies and regulations apply to management of contractors
  engaged in HUMINT collection. (See Bibliography for additional references
  on contractor management.) HUMINT collectors are not to be confused with
  CI agents, MOS 97B and WO MOS 351L (351B). CI agents are trained and
  certified for, tasked with, and carry out the mission of denying the enemy the
  ability to collect information on the activities and intentions of friendly
  forces. Although personnel in 97E and 97B MOSs may use similar methods
  to carry out their missions, commanders should not use them
  interchangeably. See Figure 1-2 for HUMINT and CI functions.
  PHASES OF HUMINT COLLECTION
  1-8. Every HUMINT questioning session, regardless of the methodology
  used or the type of operation, consists of five phases. The five phases of
  HUMINT collection are planning and preparation, approach, questioning,
  termination, and reporting. They are generally sequential; however,
  reporting may occur at any point within the process when critical
  information is obtained and the approach techniques used will be reinforced
  as required through the questioning and termination phases.
  Planning and Preparation
  1-9. During this phase, the HUMINT collector conducts the necessary research
  and operational planning in preparation for a specific collection effort with a
  specific source. Chapter 7 discusses this phase in detail.
  Approach
  1-10. During the approach phase, the HUMINT collector establishes the
  conditions of control and rapport to gain the cooperation of the source and to
  facilitate information collection. Chapter 8 discusses approach and
  termination strategies in detail.
  Questioning
  1-11. During the questioning phase, the HUMINT collector uses an
  interrogation, debriefing, or elicitation methodology to ask a source questions
  systematically on relevant topics, collect information in response to the
  intelligence tasking, and ascertain source veracity. Chapter 9 discusses
  questioning techniques in detail. (See Appendix B for a source and reliability
  matrix.)
