lol @ not wanting to deal with "paperwork" for scholarships. Gun up, kid. Free money is the best money, even if you have to put effort into it. It's a much better option than trying to sign student loans. If you can't afford to pay for school, have you tried applying for your FAFSA to see if you can't get finaid anywhere? If not, the military is a good choice, they'll sign you on, send you to school and keep you for however much you owe em for school. My friend has a 6-year contract atm.
As far as JROTC out of high school doing something for you, I'm afraid it doesn't do much I think. The only time i've heard of a "rank boost" from ROTC aka college program. The only thing 4 yrs of JROTC does for you is net you a possible scholarship from the program and eligibility to the ROTC program in whatever college you go to (if they have one). Only thing with the college program is that once you're in it, you're basically signing on to the military and you'll get put in after you graduate as an officer iirc (don't quote me on this part, i know for a fact that you have to join the military if you are in ROTC.)
edit: ey the military thing isn't entierly a scam. They're actually being picky about who gets to join since they've been cutting back. They will find any reason to drop you or not let you come back in which is why Vena is right. Not a smart deal to try and hop over the white line, y'know? And maybe they might not let you go to school then make you enlist...but i do know that there are soldiers in my uni who are there to get a degree, then enlist as an officer. Last i heard was you actually had to have your paper before they'd give you the rank.
