The dress uniform (the blue uniform) consists of the dress cap, dress coat, dress trousers, and russet-leather shoes. The straight, standing, military, white linen collar, showing no opening in front, is always worn with this uniform, with not to exceed one-half inch showing above the collar of the coat. Turndown, piccadilly, or roll collars are not authorized. When under arms, white gloves and the garrison belt (or russet-leather belt and cartridge box) are worn. The full-dress uniform is the same as the dress uniform, with the breast cord added. The service uniform is either cotton (summer) or woolen (winter) olive drab. For duty in the field it consists of the service hat, with cord sewed on, service coat or sweater, service breeches, olive-drab flannel shirt, leggings, russet-leather shoes, and identification tag. In cold weather olive-drab woolen gloves are worn; at other times, no gloves. When not in the field, the service cap is worn instead of the campaign hat. Under arms, white gloves and the garrison belt (or russet-leather belt and cartridge box) are worn. Wear the exact uniform prescribed by your commanding officer, whether you are on duty or off duty. Never wear a mixed uniform, as, for instance, a part of the service uniform with the blue uniform. Never wear any part of the uniform with civilian clothes. It is very unsoldierly, for example, to wear a civilian overcoat over the uniform or to wear the uniform overcoat over a civilian suit. Keep the uniform clean and neat and in good repair. Grease spots and dust and dirt should be removed as soon as possible. Rips and tears should be promptly mended. Missing buttons and cap and collar ornaments should be promptly replaced. There is but one correct and soldierly way to wear the cap. Never wear it on the back or side of the head. The service hat should be worn in the regulation shape, peaked, with four indentations, and with hat cord sewed on. Do not cover it with pen or pencil mark. Never appear outside your room or tent with your coat or olive-drab shirt unbuttoned or collar of coat unhooked. Chevrons, service stripes, and campaign medals and badges are a part of the uniform and must be worn as prescribed. When coats are not worn with the service uniform olive-drab shirts are prescribed. Suspenders must never be worn exposed to view. Never appear in breeches without leggings. Leather leggings should be kept polished. Canvas leggings should be scrubbed when dirty. Russet-leather (tan) shoes should be kept clean and polished. The overcoat when worn must be buttoned throughout and the collar hooked. When the belt is worn it will be worn outside the overcoat.
