You can't crack a 256-bit key directly. But it's possible there is some mistake in the implementation, either leaking data or choosing keys badly. Or maybe there's just a mole.

One of my early mentors told me “encryption is easy, key management is hard”.

That’s pretty much the root issue. Just like with physical security, the devil’s in the details.

IDK what radios they're using in Ukraine. US military radios have devices that sync to one another that rotate keys. Also the radios hop frequencies every couple of minutes. I think it's pretty much impossible to crack without the "brain" device that is used to coordinate the radios, which is closely guarded.
