The 11th Engineers was originally constituted in the Regular Army in 1916 and organized at Fort Belvoir, Virginia. During World War I, the unit deployed to France, where it played a crucial role in constructing trenches, roads, and railways under combat conditions, earning a French Croix de Guerre for its valor. In World War II, the 11th Engineers supported armored divisions in Europe, facilitating rapid advances by building bridges and clearing obstacles. Over the decades, the unit has continued to serve with distinction, adapting to changing missions and technologies while upholding its proud heritage of combat engineering excellence.
