High school to West Point to 75th Ranger to SF?

Delta Force is a unit and not an AOC or MOS. 18X, is an entry MOS or Enlistment Option, depending on what you are attempting to ask. So you could end up in Delta Force after attending West Point and serving some time in one of the Ranger BATs. If you are only a sophomore in High School, take each step as it comes along. You will learn more about the Army as the years pass, but more importantly, you will learn a lot more about yourself. Good luck and thank you for considering military service.
