Marines from Marine Fighter Training Squadron 401 pose for a group photo beside an F-5N Tiger II aboard Marine Corps Air Station Yuma, AZ, October 7, 2016. VMFT-401 is the first and only reserve squadron in the Marine Corps tasked to act as the opposing force in simulated air combat. The “Snipers” study and mimic the tactics of enemy forces to accurately reproduce what the pilots will face in a warfare environment. Now, the Snipers are training the pilots of the Marine Corps’ newest aircraft, the F-35. (U.S. Marine Corps Photo by Capt. Samuel L. Baumer)
