Airman Tonya Volpi, 919th Aircraft Maintenance Squadron, and other reservists practice CPR techniques during the 919th Special Operations Wing’s first four-day training weekend. Training classes, such as gas mask, self-aid and buddy care and law of armed conflict were offered April 1 to ensure Airmen were able to accomplish as much training as possible.
