British Army officer rank insignia Colonel on the Staff. Since 1928, a Brigadier has had the same rank badges as were displayed by a Colonel Commandant. Initially company and field rank insignia did not appear on officers' uniforms. In 1791 the War Office ordered officers to wear different graded epaulettes and wings to distinguish regimental officer ranks (Colonel to Ensign/ Cornet). This was ordered only for line Infantry officers. According to the Army Order, In 1795, a special pattern of epaulettes was ordered for Fusiliers and Light Infantry officers. Field officers of those regiments wore epaulettes over wings. Company officers wore wings. In February 1810,
United States Army officer rank insignia had silver eagles on gold epaulettes. No insignia existed yet for lieutenant colonels, majors, captains, and lieutenants—the length and size of the fringe showing the difference of grade. In 1836, shoulder straps were adopted to replace the epaulette for field duty. The straps followed the same color combination as the epaulettes; that is, the border was gold with silver insignia for all officers except those of infantry which had silver border with gold insignia. At that time, lieutenant colonels and majors were authorized leaves, captains were authorized two bars, and first lieutenants were authorized one bar on the shoulder straps.
