An insignia 2 7/8 inches (7.30cm) overall in height consisting of a dark blue pentagon, one angle up, bearing a reproduction in full color of the coat of arms of the United States all within a 1/8 inch (.32cm) yellow border.
The pentagonal shape is an allusion to the Pentagon Building, site of Headquarters, Department of the Army. The United States coat of arms is in full color as on the Secretary of the Army flag and the blue of the background is from the National Flag and stands for loyalty and trust. The gold border is symbolic of the quality of leadership provided by the Army Staff.
The shoulder sleeve insignia was originally approved on 23 Apr 1968 for Headquarters Company, U.S. Army and Headquarters Company, U.S. Army WAC. It was redesignated on 7 Feb 1978 for Headquarters Company, U.S. Army.
