That kind of skirts what the grandparent is asking, in the army for example everyone has to annually qualify with their firearm, and each mos has set of tasks they have to demonstrate competency in. All enlisted have to do this with the difference being more senior are also responsible for training. I think that's what the g p was referring to.

Also five years in the military you aren't in school, you are doing your job. So if an engineering grad did five years of work study or coop, I think they could be trusted with prod servers as you say.
