A law enforcement team consisting of two North Las Vegas Police Department police officers, one airman from 99th Security Forces Squadron, one Nevada Highway Patrol officer and one Las Vegas Metro Police Department officer, move quickly as two simulated gunman fire upon students at Lomie Heard Elementary School, March 28, 2012, during a Multi Assault Counter Terrorism Action Capabilities exercise at Nellis Air Force Base, Nev. The scenario prepared participants to respond to real-word active shooter events.
