  control measures, and safeguards associated with the use of separation. Any
  interrogation technique that appears to be cruel, inhuman, or degrading as
  defined in US law; or impermissibly coercive, or is not listed in this manual,
  is prohibited and should be reported immediately to the chain of command or
  other appropriate channels for resolution. Orders given to treat detainees
  inhumanely are unlawful. Every interrogator must know how to respond to
  orders that the individual interrogator perceives to be unlawful
  (see paras 5-80 through 5-82).
  M-19. If the order is a lawful order, it should be obeyed. Failure to obey a
  lawful order is an offense under the UCMJ.
  COMMAND POLICY AND OPERATION ORDERS
  M-20. The provisions of this appendix must be written into COCOM policy
  and/or OPORDs when using the restricted interrogation technique of
  separation.
  MEDICAL
  M-21. Commanders are responsible to ensure that detainees undergoing
  separation during interrogation receive adequate health care as described in
  greater detail in paragraph 5-91.
  TRAINING AND CERTIFICATION
  M-22. Only those DOD interrogators who have been trained and certified by
  the United States Army Intelligence Center (USAIC), or other Defense
  HUMINT Management Office (DHMO) designated agency, in accordance
  with guidance established by USD(I) to use separation, are authorized to
  employ this technique. The training must meet certification standards
  established by the Defense HUMINT Manager in coordination with
  applicable DOD components. Properly trained and certified contract
  interrogators are authorized to initiate interrogation plans that request the
  use separation, and, once the plan is approved, to employ the technique in
  accordance with the provisions of this appendix and Appendix K. Contract
  interrogators will always be utilized under the supervision and control of US
  government or military personnel (see para K-19 and K- 20). Non-DOD
  personnel conducting interrogations in DOD facilities must be certified by
  their agency and separately gain approval (through their agency's chain of
  command) for the additional technique described in this appendix. They must
  present this written certification and agency approval to the COCOM before
  use is permitted (see para 5-55).
  PLANNING
  M-23. Planning for the use of separation must include—
  • An interrogation plan that addresses safeguards, limits of duration,
  interval between applications, termination criteria, and presence of
  qualified medical personnel for emergencies (see Figure M-2).
  • A provision for detainees to be checked periodically in accordance with
  command health care directives, guidance, and SOPs applicable to all
  detainees.
  • A legal review.
