First off, I wasn't trying to make fun of you, and if took it that way, I apologize. I'm 31, so sorry. The point is, we're 30 or 40 posts in, and finally we now know you are a 27 year old black/latina female. It won't change the advice I give, but it certainly does change how I think of you. I thought you were just another guy who was doing the traditional high school to college deal. Obviously you have done some other things in your life, and hats off to you for getting where you are now. Hopefully now you can see why I was confused.
I had thought you were trying to work this lab tech deal as a civilian, which would be a good deal and help towards your resume, etc. However, if you have to enlist to work this deal, I think its a terrible idea. First off, you are a college student! Granted I had plenty of enlisted guys working for me who had college credits, but you are steadfastly working towards your degree, DO NOT ENLIST! You are officer material. This deal will only potentially be a huge detour on your quest for medical school. This isn't like signing up for a job, you are selling your body to the military, they have complete control over your life. Never trust a recruitor, they always paint the rosiest picture. To be as blunt as possible, signing a contract with the military is essentially making yourself a prostitute to a pimp, they own you. Obviously I was comfortable with that having done it twice, but I knew a lot more the second time around.
With this new information, here is my advice. Find somewhere to either volunteer or get a job helping with research. Doesn't matter if you get published, but that would help. As far as the military stuff goes, troll this page to get some level of immersion (while recognizing it is second hand knowledge). Finish your degree and apply to school. But please don't enlist as a stepping stone to getting a commission, from my end it is just counter intuitive.
As far as your best financial option, the miliary aint it. Sure you'll be more comfortable during your four years of medical school, but civilian doctors make a lot of money. That's why everyone puts up with four years of raman noodles, cause it's a small lifestyle sacrifice for four years compared to the next forty.
Apparantly you have a lot of hard decisions coming up, so please don't let them overwhelm you. These decisions don't need to be made tonight, or even this week. Focus on school, cause that's the primary reason you are even doing all this. Keep us posted, and we'll continue to try and let you in on what military crap we do know about. Thanks for hanging in there.
