DS number 2 has a athletic scholarship to a University he loves but he also wants to do ROTC and serve his country after he graduates. The school does not offer the branch of service ROTC that at this point is his ultimate goal. What are the odds that he could change services or request to serve in a different branch after graduation. He has spoken to the unit leaders at the school and the coach is all for him doing ROTC but he does not want to ask them this question for fear of hurting feelings and not starting off on the right foot. I told him he may change his mind during his years in college but was wondering how often a change of service is allowed to happen.
