USUHS is a fine school. I went there, graduated almost exactly 10 years ago. You'll learn what you should learn as a med student, you'll live well while you're there, and you'll exit without any debt.
The risk of USUHS is that it obligates you to a military residency (there are essentially NO civilian deferrals for USUHS grads), starting 5-10 years from the day you apply to USUHS. That military run residency may offer excellent or mediocre training, but you don't know what specialty you'll end up in (even if right now you think you do, odds are very high you'll change your mind at least once). It worked out great for me. Some luck was involved. How comfortable are you betting that the military residency you ultimately want will (a) have a spot for you, (b) offer top level training ... in 2022?
Once you've finished residency, nobody will ever care where you went to medical school.
What's your background? Any prior military service?
