21st Chemical Company

The 21st Chemical Company was originally activated during World War II to provide chemical defense and smoke operations in support of larger Army formations. Over the decades, the unit has participated in numerous campaigns, adapting its mission to include chemical, biological, radiological, and nuclear (CBRN) reconnaissance and decontamination. The company has served both in overseas deployments and stateside missions, supporting training exercises, disaster response, and homeland defense initiatives. Today, the 21st Chemical Company remains a critical asset, ready to respond to CBRN threats and enhance the Army’s operational capabilities.
