yeah they only have to be able to run modern nuclear instruments and weapons...
If they cant read the dials whats the problem ???
On the one hand, they don’t get to run nukes, electronics, etc. without first successfully completing the associated ‘trade schools’ and qualifying on every aspect of the thing they’re going to be running.
On the other hand ... idiots are not going to successfully complete that training, and the Navy may well be the most technological of the services. If they recruit a bunch of untrainable, unqualifiable idiots ... what is the Navy then going to do with them?
Let the ASVAB sort them out.
