Practice Relating to Rule 49. War Booty
Chad’s Instructor’s Manual (2006) states:
Prisoners [of war] may … retain items that they require for clothing, food (mess tins, water bottle, etc.), their safety (helmets, gas masks, dressings, etc.) and their identification (identity cards, etc.).
Other items of equipment (binoculars, radios, etc.), weapons and all documents of military interests (maps, rules, written orders, codes, etc.) are considered “the spoils of war” and must be handed over to the superior officers.
