Airmen with the 445th Airlift Wing participate in chemical, biological, radiological and nuclear (CBRN) training Oct. 6, 2019, at Wright Patterson Air Force Base, Ohio. CBRN training equips airmen with the skills needed to operate in an environment that has been corrupted by chemical, biological, radiological or nuclear contaminants. The training involves the use of the M50 protective mask and other protective equipment, and the airmen involved with the training practice using this equipment to better prepare them to tackle the mission.
