A gold color metal and enamel device 1 1/4 inches (3.18 cm) in height overall consisting of a gold oak tree bearing a crescent above a Roman sword, both crimson, the sword surmounting the tree diagonally from upper left to lower right.
The oak tree, symbol of strength, stands for the direct support provided by the Battalion. The Roman sword refers to the unit's participation in several campaigns in Italy during World War II. It also alludes to the Battalion's mission of providing maintenance support for small arms. The crescent, ancient emblem of North Africa, refers to the organization's initial war experience in that area. Crimson is the principal color used for the flags of Maintenance Battalions, the previous designation of the unit.
The distinctive unit insignia was originally approved for the 188th Maintenance Battalion on 31 August 1966. It was redesignated effective 18 June 2007, for the 188th Support Battalion with description and symbolism updated.
