THE FLOW OF VICTORY.
Buff represents the Quartermaster Corps. The wavy pale and the color blue refer to the water supply mission of the unit. The sword denotes readiness and service to the individual soldier. Gold stands for excellence.
The campaign service of the unit in World War II is recalled by the mural crown, for Central Europe and the Rhineland, and the fleur-de-lis for Northern France and Normandy. The griffin stands for vigilance and early responsiveness to the needs of the Quartermaster mission. Black denotes strength and resolve. Red signifies courage and sacrifice; blue refers to the 559th's water supply mission.
The coat of arms was approved effective 16 June 1993.
