I am looking to join the Guard as an RN but may run into the same issues as many others with slot allocation. I am in Rhode Island and the number of slots in such a small state is limited. My question is about the ability to re-class if a spot becomes available. In other words, would I be able to join the Guard as Infantry and play around with that until an RN slot becomes available and then petition to switch over or would I be stuck until my contract is up?
