That is the granularity of the Traveller Term. It is nothing I've added. You repeat that my assumption is flawed, but it is not an assumption, it is a viewpoint having worked and learned about technology.
Fair enough, if you say the Air Force train drone pilots for years on end, then the speciality of Remote Ops should be a specialisation of Gunner. Ie Gunner(Remote Ops), not Electronics. [I.e., Stop putting blame on the shoulders of the Electronics Engineers, or their University faculties, for something that is not their forte. ]
