Red and white are the colors for the Corps of Engineers. The partition line is wavy to represent water and the pontoon represents the type of engineer battalion.
The organization's first campaign during World War II is expressed by the face from the gold lion of the Normandy coat of arms. The fleur-de-lis is used to represent France and the Northern Campaigns of the unit during that same war. The castle turret and leaf refer to both Central Europe and the Rhineland. The leaf is black to allude to the coal regions of Alsace.
The coat of arms was originally approved for the 87th Engineer Battalion (Heavy Ponton) on 5 December 1940. It was redesignated for the 87th Engineer Battalion on 10 June 1955. It was amended to add a crest on 15 April 1966.
