Believe it or not in the period 88-91 when I was on the Taceval team at Ramstein as an augmentee the USAF pilots who had war roles at the wings we were evaluating were not allowed to see the full Radar/Missile data when flying in the 2 seater F15/16's because they were members of the NATO Taceval team. However, the following weeks when they went back for currency it wasn't a problem as they were USAFE augementies.
And don't get me started on the AIM120 when it came out USAF treated it as a 100% kill it wasn't till the SHAR's got it and we talked to them that we realised the full problems/abilities of the weapon.
