The 3rd Battalion, 43rd Air Defense Artillery Regiment (3-43 ADA) traces its origins to World War I, when it was first constituted as part of the Coast Artillery Corps in 1918. Reactivated and redesignated several times, the unit served with distinction during World War II, providing anti-aircraft defense in the Pacific Theater. In recent decades, 3-43 ADA has been an integral component of the U.S. Army’s air and missile defense, notably deploying Patriot missile systems during Operations Desert Storm, Iraqi Freedom, and Enduring Freedom. Stationed at Fort Bliss, Texas, 3-43 ADA continues to support air defense missions both at home and abroad, upholding its tradition of excellence.
