Just joined the national guard and I have a question?

So here's my dilemma. I just enlisted in the PA national guard and I am shipping for OSUT as a 19D in January. I will return in May, with plans on enrolling in the SMP program of the ROTC in the fall. However, I want to deploy and the unit I am going to isn't deploying again until Oct. 2011. I was wondering the likelihood that i can volunteer and actually get to deploy. And also, is it possible to deploy while I am actually in ROTC? My reasoning for deploying is that I feel i can become a better officer by having been deployed as an enlisted soldier and I really want to gain that experience.
