I can understand your dilemma. Best advice I can give is make sure you are talking to an AMEDD recruiter and not an enlisted recruiter. They are different. Some key things you said are throwing big red flags. 1. Nurses commission and do not enlist. 2. They do not take the ASVAB 3. it takes months to get selected for the Nurse Corps. From what I am reading, your recruiter is pushing you to take an enlistment for probably something medical but it will not be nursing. To give you some back ground on myself, I was just selected for the Navy Reserves with an ED specialty (took me about a year but I had medical issues to work through that delayed me 6 months). I am 38 with no prior service. I believe the Army reserves allows entery til 41, Navy is 47, Air Force is 47 (I think) to include the Air National Guard. My advice would be to contact an officer recruiter for each branch you are interested in and ask some questions before you swear into something that isn't what you are looking for.
