Shield
The colors, scarlet and white are traditionally associated with the Engineer Corps. The rifle and powder horn represent the Commonwealth of Kentucky and the Kentucky Army National Guard. The rifle also refers to accuracy and military preparedness. The bridge represents the Engineers mission and capabilities to overcome all obstacles. The cogwheel refers to mobility and the mechanization and technical expertise of the modern Engineer Battalion. Thirteen teeth on the wheel recall the original thirteen states of the Union and the principles and ideals that the 206th Engineer Battalion uphold and are prepared to defend.

The coat of arms was approved on 26 September 1988.
