A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of two chevronwise masoned black billets with a red ball shot conjoined below the apex all above two chevronwise gold cannon barrels, muzzles up, with two horizontal wavy blue bars between; surmounting the cannon barrels, arced below the wavy bars and terminating at the billets, a red scroll inscribed "DEPENDABLE SUPPORT" in gold letters.
Scarlet and yellow (gold) are the colors used for Field Artillery. The cannon barrels represent the overall mission of the unit and also denote the present designation. The shot and billets simulate a "break-through" and allude to the Central Europe Campaign in which the unit participated. The wavy bars between the cannon barrels symbolize the "crossing of the Moselle and Rhine Rivers" and the organization's participation in the Rhineland Campaign during World War II.
The distinctive unit insignia was originally approved for the 479th Artillery Group on 27 January 1971. It was redesignated for the 479th Field Artillery Group on 7 April 1972. It was redesignated for the 479th Field Artillery Brigade on 8 June 1979. The insignia was cancelled effective 17 October 1999, when the brigade was redesignated as the 4th Brigade, 75th Division.
