I feel like this post belongs in non-credible defense, but my guess is the next evolution of drone warfare: Autonomous Combat Assistants (ACAs).
Not an official term ofc, but as AI advances, it will allow for far greater flexibility for drones by allowing them to control themselves & take commands from local forces or human leaders directly versus being a remote controlled unit.
The drone will no longer be just a remote controlled tool, but an operational assistant, saving the human some cognitive load & allowing them to devote more energy to making decisions, for better or worse.
