Practice Relating to Rule 111. Protection of the Wounded, Sick and Shipwrecked against Pillage and Ill-Treatment
Section B. Respect by civilians for the wounded, sick and shipwrecked
Switzerland’s Basic Military Manual (1987), although it refers to Article 18 of the 1949 Geneva Convention I, does not provide explicitly for the duty of civilians to respect the wounded and sick. The commentary gives as an example, however, that if “a seriously injured parachutist lands near a farm, he shall be cared for until the arrival of the authorities”.
