Symbolism
Scarlet and white are the colors for the Corps of Engineers and a castle turret alludes to the branch insignia. Scarlet, white, blue and three stars refer to the state flag of Tennessee. Three stars are also on the Tennessee Army National Guard crest, and are used to denote the unit's allocation. The saltire and turret symbolize the overall mission of the organization.

Background
The shoulder sleeve insignia was approved on 30 January 1974. (TIOH Dwg. No. A-1-571)
