Symbolism
Maroon and white are the colors of the Medical Corps. Gold is emblematic of excellence and high ideals. The ring alludes to a wheel or movement and represents the unit's service as a Hospital Train in World War II. The ring also highlights unity and cooperation. The cross is a symbol of aid and comfort. The demi-fleur-de-lis on the ends of the cross branches recall the organization's World War II history in Europe. The serpent entwined on the rod is called The Rod of Aesculapius and was the attribute of the Roman god of medicine and healing. Green is a color associated with healing and renewal.
