  8-79. EPWs are normally vulnerable to basic incentive and emotional
  approach techniques. Most EPWs are traumatized to various degrees by the
  events preceding or surrounding their capture. They tend to be disoriented
  and exhibit high degrees of fear and anxiety. This vulnerable state fades over
  time, and it is vital for HUMINT collectors to interrogate EPWs as soon as
  and as close to the point of capture as possible. The earlier that an EPW is
  questioned the more likely he is to cooperate. And the earlier that he begins
  to cooperate, the more likely he is to continue to cooperate. It is also vital
  that the HUMINT collector be the first person that the EPW has a chance to
  talk to. This means that proper silencing and segregation of the sources by
  whoever is transporting them is an important part of a successful approach.
  8-80. The vulnerability of civilian detainees to approach techniques available
  to the HUMINT collector may be dependent on the exact nature of the
  conflict. US HUMINT collectors are obligated to treat all detainees 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. Detainees and, in particular,
  EPWs are guaranteed certain rights and privileges. The HUMINT collector
  may not take any action to remove, state that he will remove, or imply that
  he will remove any guaranteed right if a detainee fails to cooperate. Under
  the GPW, EPWs cannot be denied their rights or their privileges accorded
  them by rank as guaranteed by the GPW. Privileges afforded to them,
  however, which are not guaranteed by the Geneva Conventions or other
  applicable law or agreements, may be withheld. (See Appendix A, Section I.)
  Consult your SJA for questions concerning rights and privileges.
  8-81. The HUMINT collector is frequently under a great deal of pressure to
  “produce results.” This situation, coupled with the facts that the HUMINT
  collector is dealing with threat personnel who may have been attempting to
  kill US personnel just minutes before questioning and the fact that the
  source is in a vulnerable state, leads to a tendency to use fear-up techniques.
  This may, in some circumstances, be the proper approach; however, the
  HUMINT collector must ensure that in doing so he neither loses control of
  his own emotions nor uses physical or mental coercion.
  APPROACH STRATEGIES FOR DEBRIEFING
  8-82. Sources who are debriefed vary even more widely than those who are
  interrogated. Since debriefing is the systematic questioning of individuals not
  in the custody of the questioning forces, the HUMINT collector needs to
  engender an atmosphere of cooperation and mutual benefit. Some sources for
  debriefing include members of the friendly forces and local personnel.
  HUMINT collectors often believe that approach techniques are not required
  for friendly forces and that friendly forces should view debriefing as part of
  their duties and in their own best interest. However, this is not necessarily
  the case.
