84th Civil Support Team

Commander – Maj. Casey Henry

First Sergeant – 1st Sgt. Aaron Benson

The Wyoming National Guard’s 84th Civil Support Team is a 22-person team made of Soldiers and Airmen with a mission to support civil authorities at a domestic chemical, biological, radiological, or nuclear (also known as CBRN) incident site.

The highly specialized training each member receives makes the CST an asset to Wyoming’s response community. They have the skills and equipment to identify CBRNE substances, assess current and projected consequences, advise on response measures, and assist with procuring additional resources.

While the hope is an accidental or intentional release of unknown hazardous substances never happens, the potential remains a real threat. Each 84th CST member is specially trained as a hazmat technician to recognize the implications of hazardous material incidents. With our robust identification equipment and on-site or mobile lab support, we can keep Wyoming’s residents safe when disaster strikes.

Among our mission capabilities are:


Hazmat spills, coroner assistance for chemical ID, standby assistance.

Flood, hurricane, wild land fire support.

Ability to respond to incidents involving substances of a chemical, biological, radiological, or nuclear nature.

White powder identification, suspicious letters.

Satellite based phone and internet, and emergency radio services.

Real-time field identification of unknown biological and chemical substances.

Multi-car highway crashes, train derailments, manufacturing plant disasters.
