Because these named training exercises happen overnight, with almost no planning.
Not only that, they never happen during peacetime. They only happen when the Bear awakes.
In this case, I’d regard it more as a demo...not an exercise (in the true view that most of us participated in the past).
Also, you might want to go back and review the Air Force Europe exercise for 1983, and how this was geared to get a massive reaction out of the Soviets. They had to be ordered at the last minute to abandon a huge portion of this ‘shady’ exercise. It was more to provoke for reaction....than past exercises.
