A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a gold Oriental dragon on and above a gold steering wheel with six grips the center surmounted by a brick red disc bearing four gold chevrons, conjoined and radiating clockwise from the center of the disc so that the chevrons on the upper left and lower right point up and down and those on the upper right and lower left point right and left respectively; all above a brick red scroll partially surmounting the lower grip of the wheel and inscribed "RESPONSIVE" in gold letters.
Brick red and gold are colors traditionally associated with the Transportation Corps, the branch of the predecessor Group. The steering wheel refers to the former Group's function of movement control. The four chevrons, simulating arrowheads, stand for that organization's four assault landings in the European area during World War II. The clockwise arrangement also refers to the four basic directions. The dragon, noted for its strength and noble character, is highly esteemed in the Orient as a symbol of good fortune; he represents the former Group's service in the Vietnam conflict.
The distinctive unit insignia was originally approved for the 507th Transportation Group on 21 March 1969. It was redesignated for the 507th Support Group with the description and symbolism revised on 28 September 1992.
