Engineer Combat Battalion



An Engineer Combat Battalion was a designation for a battalion strength combat engineering unit in the U.S. Army, most prevalent during World War II. They are a component of the U.S. Army Corps of Engineers.

Also known as "Combat Engineer Battalions" (CEB), they were typically divided into four companies: A, B, C, and Headquarters and Service (H&S).

Best known for pontoon bridge construction, their duties also included serving as sappers deploying and deactivating explosive charges and unexploded munitions, mapmaking, camouflage, and a wide variety of construction services supporting frontline troops. They were also required to serve as infantry when needed.

Combat Engineers played important roles in numerous World War II battles, especially breaching the heavily fortified Seigfried Line protecting the German border and numerous defensive lines established by the Wehrmacht in Italy, including the Gustav Line. Among the most familiar for their heroism and contributions to establishing key bridgeheads in the European Theater was at the Ludendorff Bridge at the Battle of Remagen.

Their construction equivalent U.S. Navy Seabees played a crucial role establishing beachheads and airstrips in the Pacific Command's island hopping strategy of defeating Japan.
