Description
On a round-bottomed shield 2 inches (5.08cm) in width and 2 3/4 inches (6.99cm) in height overall, within a 1/8 inch (.32cm) white border a vertical blue bar concave on each side on a white field; across the center of the shield two horizontal red bars the upper one with three crenellations upward and the lower bar with four crenellations downward.

Symbolism
Scarlet and white are the Engineer's colors. The blue area denotes the Mississippi Valley affiliation and the crenellated red bars are reminiscent of the Engineer's castle, alluding to bridges and construction for which the Corps of Engineers is responsible.
