uniform, but in the field a flannel olive-drab shirt is worn. [Illustration: _Copyright, Harris & Ewing, Washington, D. C._ U. S. Army officer Olive-drab service uniform] [Illustration: _Copyright, Harris & Ewing, Washington, D. C._ U. S. Army. Officer, full dress uniform _Rank_: Major, indicated by the three stripes in the sleeve decorations _Corps_: Coast Artillery, indicated by the Corps insignia on the sleeves below the knot decoration] In garrison the saber is worn suspended by tan leather slings from a tan leather waist-belt, but for war service in the field the saber is worn with a wide tan leather belt having a suspender strap of tan leather worn from the right shoulder diagonally across the body to rings in the belt in front and in rear of the left hip. This belt was recently adopted from the British Army and is known as the “Sam Browne” belt. In the trenches and on ordinary duty in the field, officers of the Army wear the pistol belt on which the service automatic pistol is carried in a leather or webbing holster. Insignia of dull bronze metal indicating the arm of the service or the staff corps to which the wearer belongs are worn upon both sides of the collar of the service coat and the insignia of rank in bright metal, silver or gold according to rank are worn upon each shoulder strap of the coat. For certain drills and for service in the field the coat may be dispensed with, in which case the olive-drab flannel shirt is worn and the corps insignia and insignia of rank are then worn upon the collar of the shirt. The hat cord worn on the service hat by General Officers is a double cord of gold bullion with acorns of the same material at the ends, and that worn by other commissioned officers is the same except that it has black silk intermixed with the gold. Army Field Clerks and Field Clerks Quartermaster Corps wear hat cords made of black and silver twisted strands. Members of the Officers Training Corps undergoing training in the camps provided for that purpose wear a hat cord made of red, white and blue twisted strands. The overcoat is worn with the service uniform when necessary. Mounted officers wear tan boots, spurs and drab leather riding gloves with the service uniform. _The dress uniform_ consists of a dark blue cloth, single-breasted coat extending to one-third of the distance from the point of the hip to the knee; blue cloth trousers (the shade depending upon the rank and corps of the wearer as later described); a bell-crowned cap, of dark blue cloth having the coat of arms of the United States embroidered in gold on the front of the crown at the center, with a sloping visor of black patent leather and a chin strap of gold braid three-eighths of an inch in width and eight inches long attached above the visor by a small gilt Army button at each end of the visor; black shoes; white shirt, collar and cuffs; and white gloves.
