  relationship between the source and HUMINT collectors, to meetings
  whereby only the collector and the source know the meeting has occurred.
  When contact operations are conducted using this methodology, the operation
  must be coordinated in accordance with the Under Secretary of Defense for
  Intelligence (USD(I)) policy cited in Appendix J. Specific direction regarding
  documentation required for recruitment, and the designation of approval
  authority (usually the J/G2X) for recruitment of a formal contact, will be
  specified in Appendix 5 (HUMINT) of Annex B (Intelligence) to the governing
  OPLAN or OPORD.
  DEBRIEFING OPERATIONS
  5-30. Debriefing operations refer to the systematic questioning of individuals
  not in the custody of the US, to procure information to answer collection
  tasks by direct and indirect questioning techniques. The primary categories
  of sources for debriefings are friendly forces and civilians including refugees,
  DPs, and local inhabitants.
  5-31. Debriefing operations are those operations directed towards collecting
  information from a segment of the target population using primarily
  debriefing techniques. These debriefing operations are separate from the
  G2/S2 debriefing program to debrief personnel returning from missions.
  Debriefing operations often include the debriefing of personnel who may not
  usually be debriefed as part of their assigned duties.
  5-32. Normally Army debriefing operations will be directly related to
  collection tasks at the operational and tactical levels. Strategic debriefing of
  high-level personnel in response to theater and national level requirements
  is often under the purview of the DIA/DH. Army HUMINT collectors
  frequently participate in this type of collection, which is under the control,
  rules, regulations, and operational guidance of DH.
  PRINCIPLES AND GUIDELINES
  5-33. Debriefing operations are conducted under the guidelines of
  DIAM 58-11 (S//NF) and DIAM 58-12 (S//NF). They are further subject to
  applicable execute orders and the specific ROE and classified “umbrella
  concept” that apply to the specific AO.
  OPERATIONAL CONSIDERATIONS AND REQUIREMENTS
  5-34. Debriefing requires relatively unconstrained access to the target
  audience. Debriefing operations are frequently constrained by the umbrella
  concept, overt operational proposal (OVOP), and OPORDs. Debriefing is a
  time- and resource-demanding operation that often shows limited immediate
  results. Since the potential target audience is so large, debriefing operations
  require careful planning and careful screening and selection of specific
  targets.
