A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height consisting of a white Philippine sun bearing a maroon cross, each arm of equal length and terminating in an arced traverse, all between two gold arrows, points up, and above a gold scroll inscribed "MERCY AND CONSERVATION" in maroon letters, the ends of the scroll entwined around the arrows.
Maroon and white are the colors used for organizations of the Medical Department. The sun is from the seal of the President of the Philippines. It commemorates the action during World War II for which the Hospital received the Philippine Presidential Unit Citation. In addition, the sun, source of our light stands for knowledge, energy and healing. The two arrows refer to participation in two assault landings: one in the Bismarck Archipelago and one at Luzon in the Philippines. The cross is a symbol of mercy, service and physical care. It stands for the Hospital. The particular shape of the cross is identified in heraldry as a "cross felloe," so called from the resemblance of the arced terminals to the felloes of a wheel. It alludes to the Hospital's semi-mobile capability.
The distinctive unit insignia was approved on 3 September 1969.
