Authorised 18 January 1990
A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall, consisting of a gold arrowhead, point up bearing a red vertical stripe surmounted by a white quill, all between two arced branches of gold laurel and enclosed by a tripartite, dark blue scroll inscribed "SERVE" at left, "AND" at bottom and "SUSTAIN" at right, in gold letters.
Dark blue and scarlet are colors traditionally associated with personnel units. Gold is emblematic of achievement and honor; white signifies high ideals. The vertical quill refers to the number "1," numerical designation of the unit, and also symbolizes the organization's administration mission. The arrowhead represents both combat readiness and the support mission to help "direct" the soldier in his career. The color red symbolizes valor and action. The wreath commemorates the unit's campaign participation credit in the European-Africa-Middle Eastern Theater in World War II.
The distinctive unit insignia was approved on 18 January 1990.
