A silver color metal and enamel device 1 1/8 inches (2.86 cm) in height consisting of an hourglass the upper section red, the lower black, the sections triangular in shape and separated diagonally by a silver bayonet point up, pommel in lower right.
The design is an adaptation of the hourglass symbol of the 7th Division shoulder sleeve insignia which originated out of the use of two figure sevens which later became triangles to form an hourglass; likewise the colors red and black have been borrowed from the same insignia. The bayonet, a reference to the nickname "Bayonet Division" which became synonymous with the 7th Infantry Division through the unit's participation in the Korean Conflict, is the infantryman's hallmark and symbolizes the fighting spirit of the 7th Infantry.
The distinctive unit insignia was approved on 16 June 1965. It was amended to be manufactured and worn in pairs on 11 April 1966.
