Not a navy nurse or a navy recruiter but I am in the process of becoming a navy nurse. I was given a figure of 30K for 5 year commitment but no student loan repayment. I questioned my recruiter on this and she told me that they used to offer repayment but the reality is that the gap in nursing has already come to a close for the time being. I'm basically a new grad with no post grad education so I don't have a lot of room to finagle with my recruiter. If I had 1+ years of experience it would be different. Hope that answers your question.
I have heard the same figures as far as bonuses. However, i have also heard that they are fighting off applicants with a stick and most of their Nurse Corps quotas are full through FY 2012...unless you are a CCN of Psych nurse.
