The enlisted ranks also wore the "kepis". They wore a grey coat trimmed in black around the collar and cuffs. Non-commissioned officer coat sleeves were trimmed in flax-colored linen. All enlisted men had one row of brass buttons on their coats. Like the officers' buttons, they had a Roman numeral "M". Enlisted ranks were indicated by black chevrons. They were the same as those worn by the army, but instead of wearing them with the points down, marines wore them with the points up. The ranks insignia was the same. A corporal had two stripes while a sergeant had three. A first sergeant wore three stripes with a diamond in the center. A sergeant major wore three stripes up with three arcs below.
