U.S. Navy Petty Officer 3rd Class Ryan Gosch, a plane captain assigned to Electronic Attack Squadron 138, Naval Air Station Whidbey Island, Wash., marshals the aircrew of an EA-18G Growler during Red Flag 15-3 at Nellis Air Force Base, Nev., July 28, 2015. Red Flag provides realistic combat training in a contested, degraded and operationally-limited environment. These stressors provide aircrews with real-time war scenarios and helps ground crews test and improve their operational readiness. (U.S. Air Force photo by Airman 1st Class Mikaley Towle)
