Master Sgt. John N. Charyk, left, instructs airmen on how to disassemble an M16 rifle as airmen from the 108th Wing, New Jersey Air National Guard, brush up on their chemical, biological, radiological and nuclear; self-aid buddy care; post attack reconnaissance and disassembling and reassembling Beretta M9 pistol and M16 rifle skills during the Wing’s Ability to Survive and Operate Rodeo at Joint Base McGuire-Dix-Lakehurst, N.J. Feb. 9, 2014. The Wing-level evaluation shows what training areas need more focus. ATSO is used by airmen who are deploying or preparing for exercises or inspections. 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)
