A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a vertical gold doubled webbed key with a buff billet in each web, and throughout two green stylized bunches of eastern white pine needles issuing from base over the bow and flared left and right behind the webs at top, overall horizontally a seven spiral white and blue cylindrical scroll beginning at upper left at the outer pine needle and terminating at lower right at the bow of the key, inscribed on the three blue portions, "VALOR VERACITY VIRTUE," all in gold letters.
Yellow (gold) and buff are the colors traditionally associated with Supply and Service units and indicates the unit's origin. The Eastern white pine is symbolic of Maine, the unit's home state. The key denotes stewardship and reflects the command and control aspects of the organization's mission, while the billets refer to the technological processes involved in the unit capabilities. The scroll simulates undulating water and alludes to the unit's home site along the Kennebec River and also to the coastal waters of the State.
