I'm currently on active duty in the Navy. My service obligation ends in May of 2012. At that point I'll have served 10 years. I'm interested in determining how my pay, rank, time in service, and retirement would be handled if I enter med school utilizing HPSP. Specifically, 1. Do I have to leave the service prior to entering med school? 2. If I remain in the service do I get paid at my current paygrade or do I take a reduction? 3. Should I expect a reduction in rank also? 4. What time will count towards retirement? I've searched the internet looking for information about active duty utilizing the HPSP program but have been unable to find specific information about pay, rank, and retirement for people with prior service. I'll be calling a recruiter soon to ask the questions or get in contact with someone who can answer them but appreciate any insight people might have prior to that call. Thanks.
