Chapter VI : The distinctive emblem - Art. 19.
Art. 19. As a compliment to Switzerland, the heraldic emblem of the red cross on a white ground, formed by reversing the Federal colours, is retained as the emblem and distinctive sign of the medical service of armed forces.
Nevertheless, in the case of countries which already use, in place of the red cross, the red crescent or the red lion and sun on a white ground as a distinctive sign, these emblems are also recognized by the terms of the present Convention.
