Yes, I see great potential in injecting your AI into the enemies communication system. Being able to have an AI try and persuade your enemy to do things in your favor, confuse them, or censor information all processed in real time and potentially at scale of the enemy's entire army is very powerful. It could even take a passive role and serve as pure intelligence gathering of the current state of things.
Aside from the potential scale, those arent really new ideas. The scale could actually be a hindrance. Once it's used, it's future utility drops dramatically. Kind of how the intelligence community don't want to burn their zero days or exploits for low value operations. Even utilizing intelligence frorm passive opperation can tip them off.
