Ek6,
I personally think that the Guard programs are the best military programs going, for the following reasons:
1) No active-duty requirement (unless activated; not including 2 weeks per year)
2) $500 a month during med school
3) Ability to "get out" after med school (assuming you signed for 4 before starting).
4) $1000 a month during residency - stipend
5) $500 a month during residency - drill pay
6) If you find out that you dig the military route, you can always go full-time active later.
7) $80k in loan repayment
8) If you take the $1000 a month during residency, you owe 3 years of reserve time, then you're free.
9) The $80k in loan repayments can be done on a ~year to year basis
10) Often VERY flexible schedule to get your drill time in.
11) Did I mention no active duty requirement? This is all in the RESERVES.
12) All the regular benefits of military service are available, professional, personal, community service etc.
13) Ability to be paid for clinical elective rotations during the 4th year of med school.
The "bad" side of the Guard, from my perspective:
1) It's the Guard (okay don't shoot me).
2) You still have to take loans for med school.
3) There's no equivalent Navy program (so going active in the Navy isn't an option).
I don't mean to piss anyone off with these comments. I'm prior service and realize that the active duty component of HPSP turns many folks who might be considering a trial with the military away. I'm not talking about STRAP or similar programs here.
FWIW, I've spoken with several Air Guard docs (though only at one unit) who loved their jobs. They were all primary care, and weren't abused, activated, or otherwise unhappy. They were activated for Bosnia and the Gulf though...
