Maroon and white (silver) are the colors associated with the Army Medical Corps. Blue signifies loyalty and devotion; green denotes good health and vitality. The staff of Aesculapius, the mythological god of medicine, represents life-giving powers and wisdom. The blue triangle charged with a red disc is adapted from the state flag of Ohio and refers to the unit's home area. The silver cross reflects medicine, compassion and zeal. The laurel symbolizes achievement and high ideals.
The distinctive unit insignia was approved on 19 January 1990.
