Emblems of the International Red Cross and Red Crescent Movement with Sun and the Red Crystal, are defined in the Geneva Conventions and their Additional Protocols as symbols for protective use. When used as an organizational logo, these symbols only indicate that persons, vehicles, buildings, etc. which bear the symbols belong to a specific organization which is part of the International Red Cross and Red Crescent Movement (like the ICRC, the International Federation or the national Red Cross and Red Crescent societies). In this case, they should be used with an additional specification (for example "American Red Cross") and not be displayed as prominently as when used as protection symbols.
International Committee of the Red Cross during an armed conflict was adopted by the International Red Cross Conference. Unfortunately, most governments had little interest in implementing this convention, and it was thus prevented from entering into force before the beginning of World War II. In the Interwar period, Bolivia and Paraguay were disputing possession of the Gran Chaco - a desert region between the two countries. The dispute escalated into a full-scale conflict in 1932. During the war the ICRC visited 18,000 Bolivian prisoners of war and 2,500 Paraguayan detainees. With the help of the ICRC both countries made improvements to the conditions of the detainees.
