Which military branch should I join?

[rageface]

Which U.S. military branch would fit me the best? What does each branch look for in an individual,I am looking to be an officer via the academies or a program in college,But I understand the difficulty of this task,thats why I set this challenge to myself. My dream has always been to lead marines on the battlefield,but ive been open to looking at the air force and pursue pararescue (or any MOS that will allow me to see combat,on the ground would be a bonus)or pilot(I wish),I will give any information you ask if it helps,the only thing that would stop me at all from joining the military is being far or inable to communicate and see my Girlfriend,I honestly am going to marry her no matter what it takes or what anyone says,but Ive come to a fork in the road.Military(and pursue my calling)..or another career to stay with her,I hope you understand the difficulty of this dilemna..Im only a junior in High School,So I have time to think,thanks for your help
