A Silver color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a shield blazoned: Sanguine, a bend invected of four to chief, and three to base, between a mullet and an ambulance wheel all Argent. Attached below the shield a Maroon scroll inscribed PRO PATRIA PRO HUMANITATE in Silver letters.
Maroon is the color associated with the Medical Department. The white (silver) diagonal bend represents the military belt, while the invected division line is symbolic of the sheets of the bed or stretcher. The wheel refers to the original designation of the unit as an ambulance battalion. The star is representative of the state of activation, Texas. The motto translates to For Country, For Humanity.
The distinctive unit insignia was originally approved for the 34th Medical Ambulance Battalion on 21 December 1942. It was cancelled on 15 April 1955. The insignia was restored and redesignated for the 34th Medical Battalion on 18 July 1967. It was amended to correct the symbolism on 8 November 1983.
