Army - Sergeant Major of the Army (U.S.) On 16 June 1999, Army Chief of Staff Gen. Dennis J. Reimer officially unveiled and presented the Sergeant Major of the Army Flag to the residing Sgt. Maj. of the Army, Robert E. Hall. The flag, designed by the U.S. Army Institute of Heraldry, was taken from the insignia created in 1966 to distinguish the SMA rank. The flag background is divided diagonally from the upper fly to lower hoist, in scarlet and white, with scarlet uppermost.
Although it's unclear who came up with the design and actually sewed the first American flag, we do know for sure that the Second Continental Congress passed the Flag Resolution on June 14, 1777. We now observe Flag Day on June 14 each year. Since the first flag, the American flag's design has been changed 26 times.
