Above and the following are taken from "The Army Flag and Its Streamers", a pamphlet which was originally prepared in 1964 by the Office of the Chief of Military History, in cooperation with the Office of the Chief of Information and the U.S. Army Exhibit Unit, to provide general summaries of each of the campaign ribbons authorized to be displayed on the Army flag. It was subsequently updated by the Center of Military History to add the campaigns from Vietnam.
