The 24th Air Defense Artillery Group Distinctive Unit Insignia was approved on 18 March 1970. Its broad scarlet arrowhead and the golden nebuly under it are used to symbolize a missile piercing cloud cover to denote the organization's air-defense mission. The arrow is also a symbol for a directive and therefore also suggests command authority.
Several images on the insignia are used to denote the unit's service during World War II. A golden fleur-de-lis is a reference to France, and thus represents the campaigns in Normandy and Northern France. A concave arc forms a bulge and naturally represents the Battle of the Bulge of the Ardennes-Alsace campaign. The wavy blue line stands for the Main and Rhine rivers and the areas near them, an allusion to the action of the Rhineland and Central Europe campaigns.
Also known as a unit crest or DUI, a Distinctive Unit Insignia is worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (ASU, Enlisted only) with the base of the insignia toward the outside shoulder seam. DUIs are not worn on the Dress variations of either uniform, however.
