Prior service Marine, want to Join the Army and earn a slot in a Ranger BN?

I'm a prior service Marine with five years of active duty as an 0311. I was honorably discharged as a Sergeant in April of 2009 with a RC of RE-1A, and I'm looking to join the Army and put in a Ranger package. I've already put in a regeneration package with MEPS, and have been waiting on word from them. My recruiter is a young CPL, who doesn't seem to know a lot about how this would work (I don't think any of the recruiters really know) so my question is if I come back in as an E-5 with a Ranger package, am I going to have to go to Ranger school or do RIP instead? I'd rather do RIP because from what I've learned that's a straight shot to a Ranger BN, but if I get sent to Ranger School, its a leadership school that's not exclusively for Rangers meaning I could very well end up in the general infantry population. Has anybody done what I'm trying to do before? If so what does this process look like?
