Lockdown! Creech prepares for active shooter incident
Airmen from various units lift a simulated wounded Airman during an active shooter exercise at Creech Air Force Base, Nev., March 25, 2014. The exercise with Nellis Air Force Base, Nev., tested the command and control communications between bases to better prepare for future incidents. Moulage is applied to Airmen acting as victims before the exercise begins to provide an element of realism, allow accurate evaluation of medical personnel, and provide realistic training opportunities.
