A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height consisting of a gold dodecagon charged at the center with a white disc enclosed by a red arc issuing from base and bearing four gold stars at the top of the arc; overall and throughout a maroon cross bearing a gold star above two gold fleurs-de-lis on the vertical arm of the cross. Surmounting the cross in base a red semicircular scroll inscribed "SKILLED AND RESOLUTE" in gold.
Maroon and white are the colors traditionally associated with medical units. The dodecagon, a twelve-sided device, reflects the designation of the parent organization, whose heritage and honors the Hospital perpetuates. The stars and fleurs-de-lis commemorate the unit's campaign credits earned in World War I and World War II. The red and gold stripes in base signify service in Vietnam, while the scarlet motto scroll and arced ribbon are emblematic of the unit's two Meritorious Unit Commendations, one for the European Theatre, World War II, and the other for Vietnam, 1966-1967. The cross is symbolic of medical service and care. The red ribbon and scroll form a circle suggesting mobility and speed, while alluding to all-encompassing medical care.
