It can be called "military" but it doesn't help with offenses and doesn't really help with defenses either.

I don't have a fully formed opinion on the rest of your comment, however I can definitely point out that software licensing on open source software will not stop a nefarious third party from using it. They're nefarious!

To a practical point though, information asymmetry is powerful in war, but the cat was already out of the bag for this technology as it's in public papers. The code is just an application of information that was already public, they could probably write their own version of the same code based on the papers.

This is false. Putin is not afraid of shining a very bright radar into the sky to know when missiles are about to hit them. That is the standard and reliable way to go about this.

Have you heard about the “woodpecker” signal? It was the transmission of a giant over-the-horizon early warning radar system. It is now defunct, has been replaced by more modern systems, but when it was operational you could receive it basically anywhere on Earth. That is the scale sovereigns play on.

Only people who don’t have the backing of a sovereign state need to go about detecting launches in this circumspect method.

> Some domain specific knowledge was meant to be esoteric

Yes. But this is not that.

> there are a variety of better licenses such as CC-non-commercial that allow peaceful uses of the code without allowing it to be used by literally anyone on the planet

Are you kidding me? :) In the top of your comment you worry, wrongly, about Kim and Putin using the given code. And your suggested solution is to release it under a different licence? :) You think they would care about that?
