In its 1949 version, the First Geneva Convention for the amelioration of the condition of the wounded in armies in the field, distinguishes for the first time in its article 44 between the two different uses of the red cross emblem. On the one hand is the protective sign, which is the visible manifestation of the protection conferred by the Convention on certain persons and objects, essentially those which belong to the Army Medical Service, and, on the other hand, there is the purely indicatory sign, which indicates that a person or an object is connected with the National Society, but without the protection of the Convention. Article 44 also defines in a general manner the legitimate uses of the emblem in its two meanings.
