Should I join the military? Which branch?

I’m only a sophomore in high school, but I’m starting to think about future plans, and the military has come to my mind more than once. My ma really doesn’t want me to, but she wouldn’t stop me if I did. My dad would be OK with it. So, if you’ve had this same situation, give an answer.
And I’ve also thought, “If I do enlist, which way do I go?” Marines, Navy, Army, or Air Force?
