171st Chemical Detachment

The 171st Chemical Detachment was a specialized unit of the United States Army tasked with chemical, biological, radiological, and nuclear (CBRN) defense operations. Activated during the Cold War era, the detachment provided critical support in chemical reconnaissance, decontamination, and training for larger formations. The unit played a vital role in maintaining readiness against potential CBRN threats, both in the U.S. and during overseas deployments. Over time, its missions and personnel were often integrated into larger chemical companies as the Army restructured its CBRN capabilities.
