  Chapter 7
  Planning and Preparation
  7-1. Planning and preparation is one of the five phases of HUMINT
  collection. HUMINT collection, regardless of the methodology employed,
  must be a systematic, carefully prepared enterprise. The HUMINT collector
  engages in general preparation throughout his career. He focuses that
  preparation to a specific area of the world, specific mission, and specific
  collection requirements as those become available. Finally, the HUMINT
  collector focuses his planning and preparation on a specific collection effort
  with a specific source.
  COLLECTION OBJECTIVES
  7-2. Each HUMINT collection mission is conducted for a definite purpose.
  The HUMINT collector must keep this purpose firmly in mind as he proceeds
  to obtain usable information to satisfy the requirements, and thus
  contributes to the success of the unit's mission. The HUMINT collector must
  use the objective as a basis for planning and conducting questioning. The
  HUMINT collector should not concentrate on the objective to the extent he
  overlooks or fails to recognize and exploit other valuable information
  extracted from the source. For example, during HUMINT collection, the
  HUMINT collector learns of the presence of a heretofore unknown, highly
  destructive weapon. Although this information may not be in line with his
  specific objective, the HUMINT collector must develop this important lead to
  obtain all possible information concerning this weapon.
  RESEARCH
  7-3. The key to good HUMINT collection is preparation on the part of the
  collector. The HUMINT collector must understand the environment and
  particularly its human component, the mission of the supported unit, that
  unit’s intelligence requirements, his source, and the cultural environment.
  The ultimate success of a questioning session is often decided before the
  HUMINT collector even meets the source.
  GENERAL RESEARCH
  7-4. Due to the quickly changing world circumstances, it is impossible to
  conduct all the specific research required immediately prior to questioning a
  source. General research should be completed before entering an AO and
  continues until operation completion. Areas of research include but are not
  limited to––
  • OPLANs and OPORDs. The HUMINT collector must be familiar with
  the unit OPLAN and that of its higher headquarters. By thoroughly
  understanding the unit OPLAN and OPORD, the HUMINT collector
