I am finishing my HPSP package right now in preparation for the June AMCAS submission. As a prior service guy, I would caution that the military in general (and military medicine specifically) is an entirely different world compared to civilian life. I spent a lot of time overseas with different military physicians, getting a feel for their respective opinions about practicing on active duty. While most of them (and all of the prior service folks) absolutely love it, there were quite a few that did HPSP because they thought it was a better financial move (i.e. they did it "for the money"). These folks invariably hated their jobs, and a surprising number of them ended up in a specialty they didn't want due to the needs of the Navy. While lack of debt out of school is certainly an excellent incentive, you will realistically make far less as a military physician even after you account for student loans. You have increased freedom in some respects (no malpractice, etc), but you have increased restrictions in others; for example, the OIC at my last command was an RN over three MDs. I would strongly encourage anyone considering military medicine to actually shadow or at least consult with a practicing active duty physician (not a HPSP recruiter) before making such a huge commitment. As far as USUHS goes: I spoke with a former admissions guy years ago and he said that the school overwhelmingly prefers career military people. He has since left the school, but I would bet that they are still looking for career-minded folks.
