  Chapter 8
  Approach Techniques and Termination Strategies
  8-1. Regardless of the type of operation, the initial impression that the
  HUMINT collector makes on the source and the approach he takes to gain
  the source’s cooperation will have a lasting effect on the continuing
  relationship and the degree of success in collecting information. The
  approach used will vary based on the type of operation; the operational
  environment; the status of the source; the personality, position, and identity
  of the source; and the personality and experience level of the HUMINT
  collector and the time available.
  8-2. The MPs will not take any actions to set conditions for interrogations
  (for example, “softening up” a detainee). Additionally, in accordance with
  DOD Directive 3115.09, military working dogs, contracted dogs, or any other
  dog in use by a government agency shall not be used as a part of an
  interrogation approach nor to harass, intimidate, threaten, or coerce a
  detainee for interrogation purposes. Leadership throughout the chain of
  command is responsible to ensure that HUMINT operations are in
  compliance with these governing regulations and guidelines, whether the
  HUMINT collection is to take place as part of HCT operations or in an
  internment facility.
  8-3. The only authorized interrogation approaches and techniques are those
  authorized by and listed in this manual, in accordance with the Detainee
  Treatment Act of 2005. Two approaches, Mutt and Jeff and False Flag,
  require approval by the first O-6 in the interrogator’s chain of command. The
  restricted interrogation technique “Separation” requires COCOM commander
  approval for use, and approval of each interrogation plan using “Separation”
  by the first General Officer/Flag Officer (GO/FO) in the chain of command.
  Coordination may also be required with the C/J/G2X, security, legal, or other
  personnel. Regardless of the coordination efforts required, use of all
  techniques at all locations must carefully comply with this manual and
  additional instructions contained in the latest DOD and COCOM policies.
  NOTE: The word “source” will be used in this chapter to mean any person who is
  the objective of the HUMINT collector’s approach, and is applicable in any
  collection situation unless otherwise noted in the text. This use of the term
  “source” is consistent with US Army Intelligence Center HUMINT collector
  training.
  APPROACH PHASE
  8-4. During the approach phase, the HUMINT collector establishes the
  conditions of control and rapport to facilitate information collection. The
  approach begins with initial contact between the source and the HUMINT
  collector. Extreme care is required since the success of the collection effort
