In the trenches steel trench helmets of the German pattern are worn by both officers and enlisted men. In very cold weather fur coats are worn and in the snows of the mountains white coats are worn to make the troops less conspicuous. Enlisted men wear on the left sleeve a triangle of yellow braid to show long service, one stripe for four years, two stripes for seven years and three stripes for nine years. UNIFORMS OF THE AUSTRIAN NAVY The uniforms of the officers and enlisted men of the Austrian Navy are of dark blue cloth for winter wear and of white duck for hot weather and are generally similar to those worn in the British Navy. Commissioned officers are provided with special full dress, full dress, undress, blue service, white service and white mess uniforms. The special full dress uniform (gala dress) consists of a cocked hat of the same shape as the one worn in the United States Navy but having more gold braid on it; a short double-breasted frock coat with a standing collar; epaulets; dark blue trousers with gold stripes down the outer leg seams; a sash belt of black cloth with interwoven horizontal gilt stripes and a knot and tassels of gold on the right hip; and black shoes. The collar of the coat and the cuffs are trimmed with gold lace braid, the sword is worn suspended by slings from a belt worn beneath the coat, and the rank of the officer is indicated by insignia worn upon the collar and upon the tops of the epaulets. The full dress consists of the cocked hat; a double-breasted frock coat with turn-down collar and notched lapels; epaulets; trousers the same as for the special full dress; and black shoes. The sash belt is also worn with this uniform. The undress uniform consists of a bell-crowned cap of dark blue cloth with a black mohair braid band, sloping visor of black patent leather, gold chin strap above the visor and the rank indicated by narrow gold stripes around the black band; the frock coat worn without epaulets; plain dark blue trousers and black shoes. White trousers and a cap with the upper portion of the crown white are some times worn with this uniform. The sash belt is not worn with this uniform, the sword being suspended by slings from a belt worn beneath the coat. The blue service dress consists of the blue or white cap; a square cut double-breasted sack coat similar to that worn in the British Navy; plain trousers of dark blue cloth or white duck, and black shoes. When on duty with troops ashore the sword belt is worn outside of this coat. The white service uniform consists of a white cap or white helmet; a white coat with shoulder straps of the same design as the white service coat worn by the United States naval officer except that there is a patch pocket with flap and button on each side below the waist. When under arms the sword is worn suspended by slings from a belt beneath the coat and the gold and black sash belt is worn outside of the coat.
