A gold color metal and enamel device 1 1/8 inches (2.86cm) in height overall consisting of a gold embattled band on a red enameled background above a black enameled annulet bearing a gold fer de moline. Encircling the upper portion of the device a gold scroll bearing the inscription "THE NORTHERNMOST" in black letters.
The fer de moline, an iron affixed to the center of a mill-stone and used as an heraldic representation for support, on a black annulet simulating a truck tire, symbolizes the former service mission of the organization during World War II in Italy. The embattled gold and red band, colors taken from the flag of the former Republic of Vietnam, alludes to the organization's service in that country. Furthermore, the embattled line alludes to the unit's motto "THE NORTHERNMOST."
The distinctive unit insignia was approved for the 26th General Support Group on 13 Jan 1969. It was redesignated and the symbolism revised for the 26th Support Group on 9 Nov 1979.
