I feel like a lot of those other uses are more aligned to the three letter agencies for intelligence and influence if were talking mostly about gen AI. I assume the next best place (excluding munitions and their delivery systems) would be cyber operations. But this realm is touchy and the leaders don't want to start a shooting war with cyber retaliation/strikes. The oversite, need for human in the loop, and aversion to collateral damage make AI weapons difficult to develop and deploy, especially if we earent counting older computer vison etc. It's no surprise the military is having trouble developing and deploying AI weapons in that environment.
