464th Chemical Group AAS59-3A

The 464th Chemical Group (AAS59-3A) was established during the early years of the Cold War to provide specialized chemical defense and support within the U.S. Army. Stationed primarily in Europe, the unit was tasked with the detection, identification, and decontamination of chemical, biological, radiological, and nuclear (CBRN) threats. Throughout its active years, the 464th Chemical Group participated in numerous NATO exercises, enhancing alliance readiness and interoperability in the face of potential CBRN incidents. The unit was later reorganized in the late 1980s as part of broader Army restructuring, with its legacy continuing in successor chemical defense formations.
