Shield
Scarlet and white are the colors used for the Corps of Engineers. The pale in the center of the shield represents Central Europe and further refers to the Rhineland (Rhine River) which, together with the fleur-de-lis symbolizing France, alludes to the areas in which the Battalion fought in World War II. The four branches formed by the pale and two chevrons represent the Battalion's four battle honors. The spade iron, an ancient heraldic symbol, used as a reinforcement of a wooden spade refers to digging and thus construction.
Crest
The crest is that of the United States Army Reserve.
The coat of arms was approved on 15 December 1964.
