Staff Sgt. Adrian Alvarez, 99th Security Forces Squadron

Staff Sgt. Adrian Alvarez, 99th Security Forces Squadron military working dog handler, runs with ‘PJ’, 99th SFS military working dog, during a MWD demonstration at Nellis Air Force Base, Nev., April 7, 2016. While demonstrations serve as a good way to display and inform the public of the capabilities of MWDs, they only highlight a very small portion of their mission and capabilities of the handler and the dog.
