The colors maroon and white or silver, which is synonymous with white in heraldry, are for the Medical Department. The fleur-de-lis, emblem of France commemorates the Hospital's initial combat service in Normandy during World War II. The white disc refers to the circular Indian Shield on the Oklahoma state flag. The maroon cross, signifies mercy, service and physical care; it stands for the Hospital. The serpent, symbol of wisdom and life renewal, entwined around the staff, is the traditional emblem of physicians. The design of the serpent is an Indian version in reference to the organization's home area and to its activation at Oklahoma City. The lozenge represents the eye of a Medicine Man; it denotes wisdom and watchfulness. In addition, the two figures, each with four sides, allude to the Hospital's numerical designation. The word "Sooner" is the nickname of the unit's home state. It also refers to the quickness with which the Hospital accomplishes its mission.
