A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a scarlet background with a trilobated cloud at the top bearing two black crossed cannons behind a white domed tower with black archway, (as depicted on the coat of arms of the city of Antwerp, Belgium) on a green base, surmounted overall by a vertical gold "Pershing Missile;" all above a semi-circular gold scroll inscribed "QUICK RELIABLE ACCURATE" in black letters.
Scarlet and yellow (gold) are the colors used for Field Artillery. The trilobated cloud symbolizes the Headquarters and Headquarters Battery, 56th Field Artillery Brigade's Northern France, Central Europe and Rhineland Campaigns during World War II. The crossed cannons with the Antwerp Tower allude to the Headquarters Battery's two Belgian Army Order of the Day Citations, the Belgian Fourragere for action at Antwerp and the Defense of Antwerp Harbor. Red and green are the colors of the Belgian Fourragere. The "Pershing Missile" alludes to the unique mission of the unit as a participant in the Army's first Nuclear Strike Force with missiles on constant alert (QRA).
The distinctive unit insignia was originally approved for the 56th Field Artillery Brigade on 11 April 1972. It was redesignated effective 17 January 1986 for the 56th Field Artillery Command. It was redesignated for the 56th Artillery Command 4 August 2021.
