Airmen from the 108th Wing, New Jersey Air National Guard, practice self-aid buddy care skills during the Wing’s Expeditionary Skills Rodeo at Joint Base McGuire-Dix-Lakehurst, N.J., March 6, 2015. In addition, they trained on their ability to survive and operate in a chemical, biological, radiological and nuclear environment. These skills make up the foundation necessary for all Airmen to function effectively in hostile environments. (U.S. Air National Guard photo by Master Sgt. Mark C. Olsen/Released)
