About this Unit
The 4th 155 mm Howitzer Battery was established during World War II as part of the U.S. Army’s expanding artillery forces. Equipped with the powerful M1 155 mm howitzers, the battery provided crucial fire support during key campaigns in the European Theater, including the Normandy breakout and the push across France. Renowned for its accuracy and rapid deployment, the unit played a vital role in neutralizing enemy fortifications and assisting infantry advances. After the war, the 4th 155 mm Howitzer Battery was inactivated as part of the postwar drawdown, but its legacy of precision and valor remains recognized in artillery history.
