We are still pretty anal about fixing stuff. I'll tell you none of this stuff is so hard you need an ENG degree to work out voyage repairs with the Chief. I did OK with my economics degree. As I've said before, any naval officer with their year of calc and physics has the background necessary to do most line jobs. I'll admit it's great to have a better STEM background for Nuke, though I know guys with non STEM degrees who walk on water in the Nuke community.
Great, now we just need a SEAL or EOD officer to agree and it will be nearly universal.
