A silver color metal and enamel device 1 3/16 inches (3.02 cm) in width consisting of a blue oval enclosed by a maroon collar inscribed with the words "HEALING THOSE" above and "WHO SERVE" below in silver letters and centered overall a silver Zuni sun shape surmounted at center by a buff disc charged with a maroon and silver Kachina figure; the vertical sun rays extending above and below the collar.
Maroon and white (silver) are the colors of the medical Corps. The color blue symbolizes the turquoise, a semi-precious stone of the region, and buff is a desert color. The oval shape suggests the egg, symbol of life and birth. The Zuni sun sign with its four groups of rays symbolizes life giving energy and replenishment and the four mountain ranges in the Tucson area. The Kachina figure, typical of ones used in Hopi Indian ceremonies, holds a serpent on a rod in its right hand and an eagle feather in its left; both symbols signify healing.
The distinctive unit insignia was approved on 3 October 1986.
