Symbolism
The white stars on a blue field refer to the State Flag of Tennessee, the unit's home area and the V-shape of the base alludes to the nickname, "Volunteer State." The scarlet cross is symbolic of medical care and the colors white and maroon are traditionally associated with the Army Medical Department. The outer shape is symbolic of medicine and surgery, the rounded top suggesting a capsule of medicine and the pointed bottom the edge of a scalpel.

Background
The shoulder sleeve insignia was approved on 5 August 1985. (TIOH Dwg. No. A-1-713)
