Interestingly, unmanned aerial vehicles (UAV) (now known as unmanned aerial systems or UAS) used to be called remotely piloted vehicles (RPV), which they still are--remotely piloted, that is. BTW "unmanned," "unpiloted," and "pilotless" are not synonyms. Even most missiles are piloted after a fashion (since missiles tend to have a guidance system--a pilot is a species of guidance system).
I think it would be instructive to figure out why are we not fighting about Unmanned Underseas Vehicles and Unmanned Ground Vehicles.
