Practice Relating to Rule 47. Attacks against Persons Hors de Combat
Section C. Quarter under unusual circumstances of combat
Sierra Leone’s Instructor Manual (2007) states:
In any combat operation, when enemy combatants are first captured they straightaway become POWs [prisoners of war]. The first action to be taken therefore is to:
f. Evacuate them as soon as the tactical situation permits. If you have to abandon them, you can tie them only if left where they can be found; or release them and give them food and water.
