  units, transports, and facilities from military objectives, including by marking such personnel, units,
  transports, and facilities and, where feasible, by situating healthcare facilities away from military objectives.

  distinct emblem must be displayed by medical and religious personnel and medical units of impartial
  humanitarian organizations, and on their medical transports. The distinctive emblem must be respected in all
  circumstances and shall not be used improperly. If personnel, units, transports, and facilities that are entitled
  to protection are recognized as such, they remain entitled to such protection even if the distinctive emblem
  or other appropriate markings are not displayed.
