Airmen put on mission-oriented protective posture gear during a chemical, biological, radiological, nuclear, and explosive defense training Feb. 4, 2020, at Moody Air Force Base, Georgia. During the CBRNE training, Airmen learn the different alarm colors and which MOPP gear corresponds with each alarm. The training familiarizes Airmen with the proper procedures to take when under a CBRNE attack. (U.S. Air Force photo by Airman Megan Estrada)
