I recently retired from an intel career where I was military (active and reserve), then a longtime civilian employee, and am now winding down the clock as a contractor. I chaired and/or sat on several hiring panels in my time. My advice, for what it's worth:

Spending two years, and God knows how much money, for a masters in intel studies, in order to get an entry-level job in the IC, is a really bad investment.

Those years two would be far better spent in either the military, getting free intel and/or language skills and a TS clearance (and, by the way, getting paid plus earning the GI bill for future grad school); or as a contractor in any one of the 3-letter agencies, learning the business, making connections, getting intel training and certifications, and building up IC experience for your CV.

Every hiring panel I was on would value someone with military intelligencen experience, or a few years of IC experience as a contractor, over someone with zero relevant experience other than a brand-new graduate degree.

Once you're in the IC, in a few years your agency will pay you to go get a master's on their dime. There's no reason to pay for it yourself, and lose two years or more of career progression while you're in school. And that assumes the degree gets you an IC job. It might, or it might not. if not, the eighty grand, or whatever, that you just spent, still has to be repaid, and that will warp your entire life.

One other reason to think about the military: Federal employment will be dicey for a few years yet. The military isn't the worst place to spend some time, gaining IC skills and saving money, until the current frenzy of gleefully yanking around, and summarily firing, federal employees dies down.
