Shield
The scarlet and white are the colors of the Corps of Engineers. The construction function of the Battalion is referred to by the heraldic piles symbolic of wedges. The horizontal division lines of the shield, being similar to the heraldic fess, symbolize the military belt or girdle of honor. The numerical designation is indicated by the six horizontal divisions of the shield and the three scarlet piles. The motto alludes to the story of the shield.
Crest
The crest commemorates the Battalions combat service in Europe during World War II. The white fortifications are called dragons teeth; they represent Germanys wall of defense, the Siegfried Line. The black caltrap is a defensive weapon formerly scattered over battlefields to impede progress. It stands for explosive mines and refers to mine laying and demolition work. The dragons teeth and caltrap refer specifically to the Battalions achievements in forcing an opening in some of the greatest fortifications ever constructed and in clearing mine fields for the advance of the Divisions Armor and Infantry units into enemy territory. The dragon grasping the antler refers to the capture of the strategic city of Sarrebourg in northeastern France. On that occasion men of the Battalion gallantly went into the line as Infantry. Dragon is a name formerly applied to a type of musket and later to the Soldier or dragoon who carried the musket. The antler grasped by the dragon is from the coat of arms of Sarrebourg, to which the 44th Division advanced over the roadways and bridges constructed by the Battalion.
The coat of arms was approved on 6 March 1943. It was amended to add the crest and revise the symbolism on 4 November 1969.
