A heptagonal device 2 1/2 inches (6.35 cm) in diameter, with one angle at top center, consisting of a maroon cross humetty on a white background bearing a yellow fleam, all within a 1/8 inch (.32 cm) maroon border.
The colors maroon and white, in conjunction with the cross, are indicative of the unit's medical mission. The fleam is a heraldic symbol for a surgical lancet and its form simulates the unit's numerical designation, which is repeated in the shape of the device.
The shoulder sleeve insignia was approved on 19 October 1978. (TIOH Drawing Number A-1-626)
