Description
On a red vertical rectangular embroidered device, arched convexly at top and coming to a 90-degree angle point at base, a white tower issuing from base, surmounted in the center with a black diamond-shape surmounted by a white powder horn with strap; all within a 1/8 inch (.32 cm) yellow border. Overall dimensions are 2 1/4 inches (5.72 cm) in width by 3 1/4 inches (8.26 cm) in length.

Red and white are the colors traditionally used by Engineer units. The tower symbolizes the Brigade’s mission. The black diamond signifies military constancy to the nation, in times of war and peace and the rich coal resources of the state. The powder horn signifies the 111th Engineer’s heritage as “Minuteman for Freedom,” also the unit’s motto.
