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.

In this instance the article does say "An ambitious Pentagon plan to field thousands of cutting-edge drones to prepare for a potential conflict with China has [...] struggled to find software that can successfully control large numbers of drones, made by different companies, working in coordination to find and potentially strike a target—a key to making the Replicator vision work."

So these particular "AI weapons" would appear to be munitions.
