Maroon and white (silver) are the colors associated with the Medical Corps. Red expresses valor and combat readiness. Red, white (silver) and blue are adapted from the unit's Philippine Presidential Unit Citation Award. The kris, a weapon of Southeast Asia, recalls the location of the unit's World War II campaign participation and the fleur-de-lis symbolizes their World War I service in France. The six-sided cross represents medical care; with the rayed shape reminiscent of the spokes of a wheel, reflecting the unit's past history as a mobile hospital organization. The two colors of the cross underscore the unit's service in the two World Wars. The Rod of Aesculapius, symbolizing medicine and healing, emphasizes the medical mission.
The distinctive unit insignia was approved on 6 April 1989.
