About this Unit
The Headquarters and Headquarters Company, 20th Engineer Battalion (HHC 20th EN BN), was first constituted in the Regular Army in 1917 and organized at Camp Sevier, South Carolina, as part of the American Expeditionary Forces in World War I. The battalion has served with distinction in major conflicts, including World War II—where it participated in campaigns across the European Theater—and the Vietnam War, performing a variety of combat engineer missions. Over the years, HHC 20th Engineer Battalion has supported operations such as Desert Storm, Operation Iraqi Freedom, and Operation Enduring Freedom, providing vital mobility, counter-mobility, and survivability support to maneuver forces. Today, the unit continues its proud tradition of service at Fort Cavazos (formerly Fort Hood), Texas, as part of the U.S. Army's engineer regiment.
