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.
With the 50-star flag came a new design and arrangement of the stars in the union, a requirement met by President Eisenhower in Executive Order No. 10834, issued August 21, 1959. To conform with this, a national banner with 50 stars became the official flag of the United States. The flag was raised for the first time at 12:01 a.m. on July 4, 1960, at the Fort McHenry National Monument in Baltimore, Maryland.
