A gold color metal and enamel device 1 1/8 inches (2.86cm) in height overall, consisting of a gold acorn at the top and three green oak leaves in base within the upper and lower angles of a saltire formed by two blue spears with points up and each simulating a fleur-de-lis and the staffs grasped by two gold demi-lions rampant facing center, all above and issuing from a blue curved scroll inscribed "READY TO SERVE" in gold letters.
The gold acorn alludes to the 87th Infantry Division's nickname "Golden Acorn Division" and the Division's shoulder sleeve insignia. The color blue signifies the historic Infantry service. The two lions, each bearing a spear terminating in a fleur-de-lis, commemorate that unit's participation in the European Theater of Operations, World War I and World War II. The three oak leaves refer to the three World War II campaigns in which the Division participated.
The distinctive unit insignia was originally approved for the 87th Maneuver Area Command on 28 September 1971. It was redesignated with the description and symbolism revised for the 87th Division (Exercise) effective 1 October 1993. The insignia was redesignated for the 87th Division (Training Support) effective 17 October 1999. It was redesignated for the 87th U.S. Army Reserve Support Command on 4 November 2008.
