Master Sgt. Douglas Tigner, the 82nd Training Wing military training flight chief, checks his schedule to prepare for an ordinary duty day. On Feb. 21, Sergeant Tigner's day ended extraordinarily when he and Tech. Sgt. Norman D. Hicks III, a military training leader from the 360th Training Squadron, administered a shock from an Automated External Defibrillator and cadiopulmonary resuscitation on an Airman-in-Training during physical readiness training.
