A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a white star between and above two smaller white stars, all above two white horizontal bars, and rising from base three green needle-leaf trees, the large center tree terminating above the upper bar and in front of two small trees with apexes above the lower bar, all on a red background enclosed by a gold scroll terminating on each side of the top star and inscribed "MEET THE CHALLENGE" in red letters.
The star at the apex emphasizes the command supervision mission of the organization. The unit's location in the state of Washington is indicated by the three white stars and two bars upon a red background suggested by the coat of arms of George Washington, for whom the state was named. The green needle-leaf trees also refer to the "Evergreen State." Additionally, the treetops rising to the stars allude to the spirit of the Command's motto, "MEET THE CHALLENGE."
The distinctive unit insignia was originally approved for the 124th U.S. Army Reserve Command on 30 September 1970. It was reassigned and authorized effective 16 April 1996, for the U.S. Army 124th Regional Support Command.
