  of neutral States or other States not parties to the conflict that perform civil defense activities in the territory
  of a party to the conflict, with the consent and under the control of that party.
  Civil Defense Organizations and Acts Harmful to the Enemy
  5-62. The protection to which civilian civil defense organizations are entitled ceases if they commit or are
  used to commit acts harmful to the enemy outside their humanitarian activities. Protection may cease only
  after a warning has been given that sets, whenever appropriate, a reasonable time-limit for ceasing these
  activities and such warning has remained unheeded. Merely carrying out civil defense tasks under military
  direction or control and cooperating with the military in performing civil defense tasks are not considered to
  be acts harmful to the enemy. Nor is it harmful to the enemy if some military personnel are attached to civilian
  civil defense organizations or if the performance of civil defense tasks incidentally benefits military victims.
  Military personnel permanently and exclusively assigned to civil defense organizations (and properly
  distinguished with civil defense symbols) do not lose their status as POWs if captured, but they could lose
  their immunity from attack should they directly participate in hostilities, and they may be prosecuted for their
  hostile acts while acting under the color of civil defense authority.
  5-63. Civilian civil defense personnel may bear light individual weapons for the purpose of maintaining
  order or for self-defense without losing their protections, although in areas where land fighting is taking place
  or is likely to take place, the parties to the conflict must take measures to limit these weapons to handguns in
  order to assist in distinguishing between civil defense personnel and combatants. If civil defense personnel
  bear other light individual weapons in such areas, however, they must nevertheless be respected and protected
  as soon as they have been recognized as such. The mere formation of civilian civil defense organizations
  along military lines, and compulsory service in them, does not deprive them of these protections (consider
  AP I art. 65). If civil defense organizations are participating in military activities, however, like providing
  warning to military organizations (as well as civilians), they may become military objectives.
  Marking of Civil Defense Organizations and Structures
  5-64. Under Additional Protocol I, the international distinctive sign of civil defense, displayed in figure 5-2
  below, is an equilateral blue triangle on an orange ground when used for the protection of civil defense
  organizations, their personnel, buildings, and materiel, and for civilian shelters. The parties to the conflict
  must take measures necessary to supervise the display of the international distinctive sign of civil defense
  and to prevent and repress its misuse (consider AP I art. 66).

  Cultural Property Personnel
  5-65. As far as is consistent with the interests of security, personnel engaged in the protection of cultural
  property must, in the interests of such property, be respected and, if they fall into the hands of the opposing
