U.S. Air Force Staff Sgt. Greg Chmielewski, 354th Security Forces Squadron combat arms instructor, offers shooting advice while using the engagement skills trainer at the Combat Arms Training Range, July 9, 2013, Eielson Air Force Base, Alaska. An engagement skills trainer is a computer based training module which uses air compression and a surround sound system coupled with specially designed weapons to produce a shooting experience almost as good as the real thing.
