The device was designed by Benjamin Franklin. In 1747, during the war of the Spanish Succession, the Spaniards threatened Philadelphia, coming up the Delaware as far as New Castle. Dr. Franklin aroused the people and designed a crest and flag which was carried through Philadelphia in 1748 by Colonel Taylor's Battalion. The shield on the device is that of William Penn, while the colors of the wreath, red and white, denote the predominantly English origin of the early settlements.
The distinctive unit insignia was originally approved for the 28th Infantry Division Headquarters; Headquarters Detachment, 28th Division; Headquarters Company, 28th Division; Headquarters Special Troops, 28th Division and Headquarters Detachment Special Troops, 28th Division on 6 February 1929. It was redesignated for the noncolor bearing units of the 28th Infantry Division on 10 July 1968.
