For regimental officers the insignia worn on the front of the cap are the distinctive “Regimental badges” adopted for the regiment. These regimental badges present a great variety in design and often refer to some historic battle in which the regiment has taken part or to some distinctive feature of the county or colony from which the regiment comes. In many cases the name by which the regiment is commonly known is contained in the design, in others the number of the regiment in its corps is given in the design, and not infrequently the regimental motto has a prominent place. Thus the regimental badge of the 4th Hussars, a famous cavalry regiment, is a gold circle bearing the inscription “Queen’s Own Hussars,” surmounted by a gold crown, and having on the center the number of the regiment “IV,” and on a scroll beneath the motto “Mente et Manu.” The Irish Rifles have the Irish harp surmounted by a royal crown with a scroll beneath bearing the motto “Quis Separabit,” all in green enamel. The 17th Lancers have as their insignia a skull and cross bones with the words “or Glory” on a scroll beneath, the motto of the regiment being “Death or Glory.” The 12th Canadian Infantry has a gold maple leaf bearing the number of the regiment in silver and the word “Canada” also in silver. The Grenadier Guards regiments have a gold spherical bursting shell. Chaplains wear a Maltese cross surmounted by a crown in black enamel. Officers of the Army Pay Corps wear the monogram “A.P.C.” surmounted by a crown. The insignia of the Royal Army Medical Corps consist of the rod of Esculapius with a single serpent entwined about it surrounded by a wreath and surmounted by a crown with the scroll beneath bearing the inscription “Royal Army Medical Corps,” all in gold. Both officers and enlisted men in the British Army habitually wear gilt buttons and insignia on their service khaki-colored uniforms, although when in the field these buttons and insignia are allowed to tarnish or bronze, and in many cases leather buttons are used on field service in place of the gilt buttons. The overcoat, or great coat, worn by the officers of the British Army is a double-breasted ulster quite similar in design to that worn by officers of the United States Army, but having a lapel collar and reaching only to the knee. It is made of cloth of the same color as the service uniform and has shoulder straps upon which the insignia of rank are worn.
