Path to SF....

[The Four]

Howdy
I am a high school senior who is about to submit college applications, and I have come across a dilemma. I plan and am preparing to have a career in Special Forces, but I am trying to figure out the one of the best options for me of how to get there. I will attend college before I sign-up for the military, but I am debating whether or not to take college ROTC. I seek to become an 18A someday, but I want to figure out the best way for me. The two options I have basically are either enlist 18X straight out of college, and work my way up to an 18A, or attend ROTC, commission as a 2nd LT, then try out for SF after a few years of service in the Army. I understand that ROTC will teach me important things about the military before I serve, but is it really necessary to have in order to get into SF, or will it really help me? To clear things up, my goal is to get into SF, not to necessarily become an 18A or nonetheless an Army Officer. I still plan to become an 18A, but SF is my absolute priority.
Thank you for your time.
