text: FM 2-22.3 ____________________________________________________________________________________
  A record of disciplinary punishments shall be maintained by the camp commander and shall be
  open to inspection by representatives of the Protecting Power.
  ARTICLE 97
  Prisoners of war shall not in any case be transferred to penitentiary establishments (prisons,
  penitentiaries, convict prisons, etc.) to undergo disciplinary punishment therein.
  All premises in which disciplinary punishments are undergone shall conform to the sanitary
  requirements set forth in Article 25. A prisoner of war undergoing punishment shall be enabled
  to keep himself in a state of cleanliness, in conformity with Article 29.
  Officers and persons of equivalent status shall not be lodged in the same quarters as non-
  commissioned officers or men.
  Women prisoners of war undergoing disciplinary punishment shall be confined in separate
  quarters from male prisoners of war and shall be under the immediate supervision of women.
  ARTICLE 98
  A prisoner of war undergoing confinement as a disciplinary punishment, shall continue to enjoy
  the benefits of the provisions of this Convention except in so far as these are necessarily
  rendered inapplicable by the mere fact that he is confined. In no case may he be deprived of the
  benefits of the provisions of Articles 78 and 126.
  A prisoner of war awarded disciplinary punishment may not be deprived of the prerogatives
  attached to his rank.
  Prisoners of war awarded disciplinary punishment shall be allowed to exercise and to stay in the
  open air at least two hours daily.
  They shall be allowed, on their request, to be present at the daily medical inspections. They shall
  receive the attention which their state of health requires and, if necessary, shall be removed to
  the camp infirmary or to a hospital.
  They shall have permission to read and write, likewise to send and receive letters. Parcels and
  remittances of money, however, may be withheld from them until the completion of the
  punishment; they shall meanwhile be entrusted to the prisoners' representative, who will hand
  over to the infirmary the perishable goods contained in such parcels.
  III. JUDICIAL PROCEEDINGS
  ARTICLE 99
  No prisoner of war may be tried or sentenced for an act which is not forbidden by the law of the
  Detaining Power or by international law, in force at the time the said act was committed.
  No moral or physical coercion may be exerted on a prisoner of war in order to induce him to
  admit himself guilty of the act of which he is accused.
