Back in WWII the British recruited academics as intelligence analysts. I recollect reading about a noteworthy analyst who was a college professor of Classics.
I think that intelligence analysis is more a matter of innate aptitude than formal education. Some people are good at it.
Certain kinds of Operational Intelligence, this is true. But for Technical Intelligence you need a good solid technical background, and that same sort of questioning mindset.
The "Red Team" often does things somewhat differently than the blue team. There is usually more than one way to skin a cat, and the Soviets tended to make different design trade offs than US defense contractors and their government program managers.
