Practice Relating to Rule 25. Medical Personnel
Belgium’s Law of War Manual (1983) defines medical personnel with reference to Articles 24–25 of the 1949 Geneva Convention I and Article 8 of the 1977 Additional Protocol I. The manual states that permanent medical personnel “shall be respected and protected at all times: they may not be made the object of attack but may not participate in hostilities either”. According to the manual, temporary medical personnel “enjoy the same protection only when they perform medical functions”.

Belgium’s Teaching Manual for Soldiers states:
The protection accorded to the wounded would be illusory if the civilian and military medical services which are specifically set up to treat them could be attacked. Hence, medical services, identified by the Red Cross (or Red Crescent in certain countries), are not considered combatants or military objectives even if they wear the enemy uniform or bear its insignia. Enemy medical personnel … may not be attacked.
