The insignia of rank for Warrant Officers are as follows:
Interne.—A rod of Esculapius with a single serpent entwined about it, in silver.
Pharmacist.—No rank insignia on shoulder straps. On the sleeves of the dress and service coats five inches above the edge there is a “cachet” indicating the rank. This consists of a circular piece of maroon broadcloth one-half inch in diameter surrounded by a circle of gold embroidery one-eighth of an inch wide. For the white service and khaki uniforms the “cachet” is made of enameled metal. Pharmacists of the third class wear one such mark, those of the second class two and those of the first class three.
