A gold color metal and enamel device 1 1/8 inches (2.86cm) in height overall consisting of a dark green disc within an annulet divided horizontally orange and gold, the orange half inscribed "EXCELLENCE" in gold letters, and the lower gold half forming an open wreath of laurel; on the upper part of the disc and extending onto the annulet a gold Vietnamese hat bearing three horizontal orange bands, the center band cut at regular intervals, in base surmounting the wreath and extending over the lower part of the hat an orange fleur-de-lis.
The fleur-de-lis, emblem of France, refers to the unit's initial activation in that country and to its World War II service in the European Theater. The distinctive Vietnamese hat stands for service in Vietnam. The three orange bands on the gold hat allude to the flag of the Republic of Vietnam. The center band is broken to represent minus signs in reference to the negative charge of electrical impulses. The three bands stand for lines of communication and refer to the unit's major mission of providing and expanding electrical communications systems and facilities. The wreath of laurel is the traditional award for high achievements; it alludes to the motto "Excellence." The color orange is used for the Signal Corps; green refers to the jungles and terrain of Vietnam.
The distinctive unit insignia was originally approved for the 2d Signal Group on 21 Aug 1968. It was redesignated for the 2d Signal Brigade on 17 Oct 1979.
