About this Unit
The 2nd Battalion, 61st Air Defense Artillery Regiment (2-61 ADA) has a distinguished history of service within the U.S. Army’s air defense artillery branch. In the mid-20th century, elements of the 2-61 ADA were stationed in South Korea as part of the United States’ commitment to the defense of the Korean Peninsula following the Korean War. Their mission included operating air defense systems to protect key installations and allied forces from aerial threats, particularly during periods of heightened tension with North Korea. Over time, the unit contributed to the deterrence posture and collective security of U.S. and South Korean forces before being inactivated or reflagged as part of broader force restructuring.

Nike Hercules Missiles: During its tenure in South Korea, the unit operated the MIM-14 Nike Hercules missile system, a nuclear-capable surface-to-air missile designed to intercept high-altitude bombers.

Critical Defense Role: The battalion’s positioning in South Korea placed it on the front lines of the Cold War, defending Seoul and key military installations from potential aerial attack.
