Air Force PJ!?!?!?!?!?!?!?!?!?!?

I have my bachelors degree, but instead of becoming a CRO (Combat Rescue Officer), I want to enlist and become a regular PJ after the two years of training. My recruiter told me that CROs dont get all the action that a regular PJ sees, also they don't receive the full EMT Training that PJs do. Can anyone help me out by explaining what a CRO really does, and give their personal opinion.
