I checked out the other posts on this topic and couldn't find the answers to some of my questions so I'm just going to post them here: 1. I am currently a 1st LT in the army medical service corps in the IRR. If I accept the HPSP scholarship, can I simultaneously remain in the IRR while on scholarship? 2. Since I have already completed OBC, would I be able to conduct med research in a military facility the summer between MSI and MSII years, when everyone else will be in OBC? (I completed the 10-week OBC course last spring). both USUHS and HPSP 3. Will time spent as a student at USUHS be counted towards time in according to the pay scale. I currently have close to four years in (post-completing ROTC) and I was wondering if after med school it would still be considered 4 years or will it be 8? 4. In terms of rank, I have been a 1LT since May 2000. Since you are automatically made a captain when you complete med school, will the time I spent as a 2nd and 1st LT be added to my time in rank so that I will make major before my classmates that have no prior service, or am I back to square 1? Your help is much appreciated.
