The 18th Engineer Brigade (Theater Army) is an engineer brigade of the United States Army. It is currently a subordinate unit of 21st Sustainment Command (Theater) and is headquartered at Conn Barracks in Schweinfurt, Germany. Soldiers of the 18th Engineer Brigade provide various supportive duties to other Army units, including construction, engineering, and mechanical work on other Army projects.
The brigade served in Europe during World War II, a fact which was included on its Distinctive Unit Insignia when the 20th Engineer Brigade received one on 10 February 1966. The four corners of the crenelated square allude to their four campaigns in World War II, Normandy, Northern France, Rhineland and Central Europe.
The 18th Engineer Brigade later deployed to South Vietnam, during the Vietnam War, where its battalions saw six years of combat service and supported fourteen campaigns, building infrastructure for both military and civilian projects. The brigade participated in a massive number of road construction projects and airfield constructions, supporting numerous infantry units and operating all over Vietnam. After serving in Vietnam, the brigade became attached to Seventh United States Army. It has since undertaken and completed numerous projects in support of US Army, Europe, and participated in Operation Desert Storm, Operation Enduring Freedom, and Operation Iraqi Freedom.
