A couple questions about designating aviation out of NROTC. If I understand correctly, through BDCP you can apply for SNA more than once, with NROTC do you only get one chance? If I don't receive my first choice, does this mean I am out of chances to be an aviator or can I apply again? Also if I wanted to get PRK, how would this work with NROTC? I understand that I would have to fund it, but do I have to have it done before it is time to apply for aviation or do people commonly receive this after they graduate? Not sure how PRK works for mids in NROTC, especially with the new vision standards. Thanks for any input.
