Scarlet and white are the colors for the Corps of Engineers. The arched bend, representing a road, symbolizes an outstanding accomplishment of the organization - participation in the construction of the Alcan Highway. The four fleurs-de-lis represent the World War II service in Europe.
Scarlet and white are traditionally used by Engineer units. The gear and pickaxes symbolize the traditional Engineer mission; the five pickaxes and eleven gear cogs denote the decorations awarded to the battalion for participation in World War II and Vietnam. The bamboo handles and torteau with star signify the unit's service in Vietnam.
The coat of arms was originally approved on 18 Apr 1952. It was amended on 24 Feb 1999 to include a crest for the 35th Engineer Battalion.
