Airman 1st Class Bryan Chang, an emergency manager from the 106th Rescue Wing, strips off his Level A hazardous material suit during exercises on the first day of Global Dragon on March 9, 2015. Through the first set of scenarios, airman trained in Level A Hazardous Material suits, using their equipment to test for chemical, biological, radiological and nuclear (CBRN) contamination. The training emphasized coordination within small teams, with each airman working to support their wingman to accomplish the mission. Exercise Global Dragon is a two-week long course taking place at the Guardian Center in Perry, Georgia. The Guardian Center houses several training facilities that simulate demolished city blocks, flooded towns and CBRN-contaminated areas.
