We had two Aggressor Sqdn's here at Nellis - F-5's
Fun job, for awhile, then it got old. They traveled constantly to other bases to provided the "bad guy" role.
The really cool part was the fact that the F-5 was a "low tech" bird, going up against the (then) newest "high tech" the AF had to offer - F-15 / F-16's. The Aggressor pilots routinely (as in 'flick that spot off my flight suit') bruised / mangled / destroyed the ego's of the "high tech" pilots.
The F-5's went away and were replaced by a single squadron of F-16 Aggressor's.
I think they are still operating, not sure.
The F-5, in skilled hands, was a capable little bird.
They are.
F-5, The White Rocket. (well the Nellis ones were camo, but I digress) Barron Flight IIRC.
I worked the EW ranges for years. It was fun to 'shoot down" hotshot pilots. FWIW, we lost some aircrews, the training was at that time, so intense and realistic.
We took our motto from the 64th - YGBSM!
