A silver color metal and enamel device consisting of a maroon disc 1 1/8 inches (2.86 cm) in height with a silver sun of seven rays rising from its base, the second, fourth and sixth rays straight and throughout and behind a white horizontal band across the center portion of the disc, with, at teach end, a vertical silver wing reversed on, and extending beyond the edge of the disc. At the top on a silver scroll that follows the curve of the disc and overlaps the top of the wings, the inscription "SERVICE OVER SELF" in black letters.
Maroon and white are the colors used for Army Medical Service; the disc simulates a wheel and refers to the unit's ability to operate fixed or mobile. The white band represents both air and emergency field evacuation as well as alluding to first aid dressings and bandages. The rising sun symbolizes the steadfast reliability of the organization, with the seven rays signifying the numerical designation, and the three long straight rays to the physical, mental and spiritual aspects of man, the object of this duty.
The distinctive unit insignia was approved on 14 February 1967.
