1:4 ADA

The 1st Battalion, 4th Air Defense Artillery Regiment (1-4 ADA) traces its lineage back to the original 4th Regiment of Artillery, constituted in 1821. Throughout its history, the unit has participated in numerous conflicts, including the Civil War, World War II, and the Gulf War, evolving from coastal and field artillery missions to modern air defense roles. In recent decades, 1-4 ADA has been stationed in Europe, where it provides critical short-range air defense capabilities using systems such as the Avenger and Stinger missiles. The battalion continues to serve as a key component of U.S. Army Europe’s integrated air and missile defense, supporting NATO and allied operations.
