A silver color metal and enamel device 1 3/16 inches (3.02 cm) in height consisting of a serpent in gold tones entwined on a silver torch enflamed red superimposed on two silver swords with red grips crossed saltirewise, all upon a blue cross interlaced by a maroon scroll inscribed "FIGHTING" on the left, "FOR" at top and "LIFE" on the right in silver letters.
Maroon and white (silver) are the colors traditionally associated with the Army Medical Corps. Blue, which represents loyalty, is taken from the Indiana state flag, and the cross denotes medical aid, assistance and compassion. White (silver) suggests honesty and integrity; red is symbolic of vitality, courage and zeal. Gold signifies high ideals, excellence and achievement. The torch is also adapted from the state flag and reflects the unit's home location while alluding to influence, knowledge and guidance. The serpent entwining the torch recalls the staff of Aesculapius, the mythological God of Medicine and represents life-giving powers. The crossed swords imply military strength, preparedness and underscore the unit's motto.
The distinctive unit insignia was approved on 24 September 1990.
