I want to join the military?

I plan to enlist at 20 into the navy and be a seabee, a builder to be more specific. I left high school in 10th grade and got a GED recently im 19 now and want to enlist. I want a job that is a mix between a combat role and a role that will help me have opportunities after I discharge. I thought a seabee would be a good role cause i’ve been told they are closer to the marines than sailors and get trained in combat. I like that idea and being able to get skills in trades like carpentry and masonry. Could someone that has experience as a Marine or Seabee tell me how accurate my knowledge is to the real thing?
