The 527th at Alconbury did a pretty good job of 'Red Air' aggressor work back in the early '80s. Their F5s were hard to spot and very nimble - who remembers hearing "Tracking...tracking...Atoll...Atoll!". Tried to pull one up in the vertical once - and ended up with more AoA units than IAS. Oops!!
During my F-4 course, we had some DACT towards the end. The opposition were a pair of Hunters with 100 gallon tanks flown by 79 Sqn instructors versus our fatigue conserving g-limited Charlie fit jets. Oh how they chuckled!
