DS just received 3 yr AROTC Scholarship to a SMC where he is enrolled and planning to attend. DS had applied to USNA and USMA unsuccessfully and had decided he would go the SMC route enroll in NROTC with goal of USMC Commission. Now the AROTC arrives and while we are grateful and very excited about this new development it does change things.... We are encouraging him to accept with the expectation that once he participates in AROTC he will be happy with the decision. Are there cross-branching opportunities if that is not the case?
