So I'm an incoming freshman at San Francisco State University and since my junior year I've been highly considering joining ROTC and becoming an officer, but I'm having the hardest time choosing a branch. I really want to join AFROTC since Berkley has a cross town agreement, but I was curious what happens if you're not selected for summer field training, not saying that'll happen or anything I've been a consistent student all my life and graduated from one of the hardest high schools in America. But what happens if I don't make SFT, does it just like stop there or can I go do Army ROTC. What should I do to make sure I get selected for SFT? Does anyone know the selection rate at Berkley? I don't really have a firm understanding on how ROTC for either branches work besides the fact you get commissioned after your sophomore year. I've seen things on forms such as MSI-MS4, and 100-400s and things like 250s can someone explain what those are to me also. Thank you.
