A disk consisting of three horizontal stripes (red, white,
and blue) was personally selected in World War I by General
Pershing for wear by all personnel assigned to General
Headquarters, American Expeditionary Forces. The source of the
design is said to have been the red, white, and blue horizontally
striped brassard worn as a distinguishing mark by staff officers
when moving about on duty in congested areas at the front in World
War I. In 1941, the brassard prescribed for General Headquarters,
American Expeditionary Forces consisted of three stripes of blue,
white, and red, the blue uppermost. Therefore, the shoulder-sleeve
insignia was authorized to be worn with the blue uppermost to
conform to the manner of wearing the brassard
