Oh there's plenty of menial and labor But honestly if you are used to working hard already, you will probably think of it as a breeze. Things unavoidable no matter what job you get in the navy are: cleaning, painting, cleaning, painting, (if you can't get it clean, try painting it), and standing those reactor plant watches gets tedious as well. But the trade-off is you will go see things that the average person never gets to see. As a West Coast Sailor I got to go to Australia, Singapore, Guam, Bahrain, Qatar, Dubai, Hawaii, Canada, Mexico, and around South America. You never have to worry about job security, housing, utilities, food, or health insurance, as these are all free. Much of your gross pay is also tax-exempt. Even if you decide not to do nuclear power, there's plenty of other extremely technical jobs in the navy to choose from.
