The outcome is hardly surprising since A-10s don't even have a missile warning system, and were never intended to engage fighters, and USAF F-16s have rather primitive MWS and RWR and no active EW. There is no mention of whether F-15 or Growler cover was provided. If not, the jets were sitting ducks in a scenario that only a lunatic would plan.
Nonetheless this exercise was set up and given unusual publicity at a point where, by total coincidence, the USAF is trying to ditch the A-10 and use its people to support F-35.
No shenanigans here, I'm sure.
