121st Signal Battalion

The 121st Signal Battalion was first constituted in 1917 as part of the U.S. Army Signal Corps and served in France during World War I. Reactivated for World War II, the battalion provided vital communications support to the 1st Infantry Division throughout campaigns in North Africa, Sicily, and Europe, including the Normandy landings and the push into Germany. During the Cold War and into the late 20th century, the unit was stationed in Germany, supporting U.S. Army Europe with advanced signal operations. The 121st Signal Battalion was inactivated in 2006 as part of Army transformation and restructuring initiatives, closing a distinguished chapter in military communications history.
