John Yates is an U.S. Air Force pilot who once operated for the Intelligence Convergance Group.
Yates and his squadron were patrolling the air space around Wilkes Ice Station when they spotted a rogue British fighter, which they quickly took down, but not before it fired a nuclear missile at Wilkes.
After Schofield and his surviving allies escaped the detonation in an experimental plane, Yates intercepted his communications and relayed his orders to have Schofield escorted to a Navy aircraft carrier. After asking for Yates' name and realizing that he was ICG, Schofield refused, forcing Yates to resort to plan b - fire and destroy him.
Luckily for Schofield, his aircraft had an experimental cloaking technology that hid him from view, both visually and on radar, to Yates' surprise. Yates was barely able to make out a distortion in the air where the aircraft was, but was too late as Schofield fired missiles upon Yates and his squad, destroying their F-22's with ease.
