ShieldThe two stars allude to the arms of the town of Bischwiller in France (Alsace Ardennes). Considered a "hot spot," the unit suffered its first casualties there. The wavy chevron represents Central Europe, the area in which the unit constructed bridges. The edelweiss refers to Rhineland. The spade with edelweiss together with the two stars represent three battle honors awarded the unit for services in the European Theater, World War II.
CrestThe ring and helicopter blades suggest a helipad, highlighting the unit's airmobile equipment support mission, while symbolizing accuracy and precision. The arms of the helicopter blades symbolize the four decorations awarded to the unit for service in Southwest Asia. The torteau, rice stalks and star, adapted from the Vietnam coat of arms represents combat service in that theater of operations.
The coat of arms was approved on 3 June 1965. It was amended to add a crest on 25 June 2013.
