The Red Cross and the Red Crescent are symbols which are used by organizations which are part of the International Red Cross and Red Crescent Movement, namely the International Committee of the Red Cross (ICRC), the International Federation of Red Cross and Red Crescent Societies (IFRCS), and more than 180 national Red Cross or Red Crescent Societies. In addition to that, these symbols have a special meaning derived from the Geneva Conventions. An additional symbol, the Red Lion and Sun, was used from 1924 to 1980 by Iran. The national society of Israel, Magen David Adom, uses an own symbol, the Red Star of David, which is not recognized as a protection symbol by the Geneva Conventions. An additional symbol, the Red Crystal, was introduced by adoption of a third additional protocol on December 7, 2005.
For indicative purposes only, the above symbols or combinations of them can be incorporated inside of the new Red Crystal emblem. For example, a combination of the Red Crystal with the Red Star of David will likely be used by the Israel society Magen David Adom (MDA) for humanitarian missions abroad. Similarly, the national societies of Eritrea and Kazakhstan will probably use a combination of the Red Cross and Red Crescent inside of the Red Crystal as their emblem. For protective use, the Red Crystal can only be used without any additional symbol inside. In principle, the Red Lion with Sun (alone or in combination with the other symbols) could be used inside the Red Crystal as well. As the Red Lion with Sun is not in use since 1980, such combination is very unlikely to be used in the future. For that reason, it is not depicted here.

The following pictures are examples of the above symbols being used in the context of the military. Such application for members, vehicles or buildings of armed forces and similar situations is governed by the Geneva Conventions. This is called protective use and does not indicate affiliation of the respective persons or facilities with the International Red Cross and Red Crescent Movement. Under the rules of the Geneva Conventions, the symbols are therefore used without any textual designation.
