HHB 4:43rd ADA

**Headquarters and Headquarters Battery, 4th Battalion, 43rd Air Defense Artillery Regiment (HHB 4/43rd ADA)** traces its lineage to the historic 43rd Coast Artillery, originally constituted in the early 20th century. Reactivated and redesignated multiple times, the battalion has served in key locations worldwide, adapting from coastal defense roles to cutting-edge air and missile defense missions. In recent decades, HHB 4/43rd ADA played a pivotal role in the defense of critical assets and allied forces in the Middle East, particularly during Operations Desert Storm, Iraqi Freedom, and ongoing missions in the CENTCOM area of responsibility. Today, HHB 4/43rd ADA remains an integral part of U.S. Army air defense, employing the Patriot missile system to safeguard U.S. and coalition forces against evolving aerial threats.
