Marking of medical units and establishments
The distinctive flag of the Convention shall be hoisted only over such medical units and establishments as are entitled to be respected under the Convention, and only with the consent of the military authorities.
In mobile units, as in fixed establishments, it may be accompanied by the national flag of the Party to the conflict to which the unit or establishment belongs.
Nevertheless, medical units which have fallen into the hands of the enemy shall not fly any flag other than that of the Convention.
Parties to the conflict shall take the necessary steps, in so far as military considerations permit, to make the distinctive emblems indicating medical units and establishments clearly visible to the enemy land, air or naval forces, in order to obviate the possibility of any hostile action.
