A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height consisting of a black fleur-de-lis surmounted by two gold color metal spanners in saltire, overall a gold color metal decrescent, the entire supported by a red scroll inscribed “THAUMATURGE” in gold color metal letters.
The red, gold and black refer to the three geographical divisions of Tennessee in which units of the Battalion are located. The two spanners (16th Century wrenches) symbolize the maintenance and supply capabilities of the organization. The decrescent alluding to the flag of Tunisia and the fleur-de-lis, representing France, refer to the areas where the Battalion serviced during World War II. The motto translates to “A Worker of Miracles or Wonders.”
The distinctive unit insignia was approved on 10 March 1967. It was rescinded on 28 February 1975.
