A Silver color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a shield blazoned: Gules, on a pall Argent four mullets of the first, in chief a snake coiled to strike of the second.
The shield is red and white, colors traditionally associated with the Engineer Corps. The pall is adapted from the unofficial seal of the city of Chicago. The four mullets indicate the major engagements the predecessor unit participated in during World War I, while the snake is representative of duty on the Mexican Border.
The distinctive unit insignia was originally approved for the 108th Engineer Regiment on 25 November 1930. It was redesignated for the 108th Engineer Battalion on 9 October 1942. It was rescinded on 26 December 1974. The insignia was reinstated and redesignated for the 44th Support Group with the symbolism revised on 17 July 1992.
