A silver color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a silver scallop shell of seven ribs bearing a maroon Greek cross all enclosed on the sides and at top by an undulating maroon scroll inscribed "UNITY AND COMPASSION" in silver letters.
Maroon and white (silver) are the colors used for the Army Medical Department, and the cross is symbolic of aid and assistance. The shell's real function, to protect life, refers to the unit's mission, and the seven ribs allude to man's seven functions to see, hear, smell, taste, feel, speak and animate. A scallop shell is an ancient symbol for a journey to a foreign land and represents the unit's service in Saipan during WWII.
The distinctive unit insignia was approved on 29 September 1970.
