A Silver color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a shield blazoned: Per bend dove-tailed Argent and Azure, two whelk shells counterchanged. Attached below and to the sides of the shield is a Silver scroll inscribed "SUPPORT BY INTELLIGENCE" in Black letters.
The two shells and the dove-tailed partition line stand for the three general functions of a Military Intelligence unit, i.e., the collection, processing and dissemination of information. The whelk shells, which receive and transmit sound waves and vibrations, refer to the collection and dissemination of information; the fitting together of the two parts of the shield by means of the dove-tailed line, refers to the process of interpreting and collating separate pieces of information to form an integrated whole. Blue and silver are the colors used for the Military Intelligence Corps. The counterchanging of the colors of the shells alludes to the counterintelligence function of the unit.
The distinctive unit insignia was approved on 4 November 1966.
