I submit the issue of training is a red herring also.
Yes, a military operator will require extensive training, but that is required so the they can operate and maintain, assess performance, undertake proper c2 functions etc.
Given a reasonable competence (how many read computer manuals today?) and trial and error I suspect that they could switch on, get a lock and fire. Niceties such as roe, eccm, identification, speed of reaction and reload are all unnecessary.
