I don't think it's a bad thing to be ambitious and keep your goals in sight, but look now to the 25 meter target before deciding where you'll be going to medical school. Get good grades, go to college and get good grades, and finish your premed requirements in the first 2 years. Though med schools require a 4 year degree, the basic prereqs (physics, chem, bio, ochem, and english, +/- calculus or statistics) can be finished in the first 2. Distinguish yourself academically and personally. Only about 1/3 of med school applicants get in.

You would do well to drop some of the common vernacular from your writing if you wish to succeed in the fields of medicine or special operations, and particularly when posting here.

Also figure out what you want to be: PA, or physician, and pursue that. They are not the same thing, and PA is not a "fall back plan". In fact, the prerequisite coursework for PA is more extensive than that for medical school.

As far as a route to go to get to med school, I cannot speak to what is best for you. Only you know that. There are many physicians in special operations who were enlisted warriors long before med school, and they make capable, focused med students, then return to special operations as physicians. Others come to special operations after med school as a GMO or residency trained physician. Being a physician in special operations does not mean you are running around with an M4 shooting bad guys in the face and performing thoracotomies with a pocket knife and 550 cord. If you want to be a "special operator", enlist as a soldier and earn your title like the Quiet Professionals on this site. To that end, you will find ample of solid information on this site, and I am unqualified to advise you on that point.

Specialty is determined by the student, though there are limited slots in the military for some specialties, and the number of "points" you have for things like prior service, GMO time, awards, etc. will help determine where you end up for residency. In the civilian world, you apply to residencies (typically all the same specialty) and rank them in order based on your preferences. A computer compares your list with the lists of the programs, and matches you with a residency slot.

The military will be happy to pay for your med school, just know what you'll give in return.
USUHS: Pros: you get a salary while in med school, which is good. You get better plugged into the military system and meet and greet the people you need to know to get some of the more unusual assignments. Several programs like TCCC, C4, Airborne, and others are part of the regular med school curriculum.
Cons: payback time is longer, on the order of 7 years after residency instead of 4. Specialty choice can be limited by the number of military slots available in that specialty. You can get a deferment to go to a civilian residency of your choice, but don't bet on it.

HPSP: Pros: you can go to a civilian med school of your choice while Uncle Sam picks up the tab for tuition, books, fees, and equipment. You will pay back 4 years AD after residency, and will emerge from that debt free.
Cons: Specialty choice may be limited. If you want something competitive, you may be beat out by someone who has done GMO time and has more points than you, leaving you in a residency you may not want. You get about $1000/month stipend, which isn't much to live on.

FAP: Pros: You can go to a .civ med school and match in whatever residency you choose, just like all the .civ folks. US pays you a stipend through residency, but nothing for you in med school. Payback is 1:1 for each year of residency.
Cons: You still gotta come up with the financial aid to pay for med school.

STRAP: Pros: Like the FAP, only payback is 2:1 in the Reserve rather than 1:1 active duty. If you want to work with combat arms, you'll have a tough time doing it from the Reserves.

The answers to many of your questions about medical school are probably better found over on studentdoctor.net.

Good luck to you.
