Navy Corpsman - Fleet Marine Training+Duties?

I just recently signed on to the US Navy to be a Hospital Corpsman. I didn't want a job in a hospital somewhere, so I signed on to be a Fleet Marine (my first choice in the military was to be a Marine). I know this requires me to serve in combat situations as first response medical to combat wounds as well as other, simpler issues. That was one of the primary reasons I signed on for this rating. I was curious what the specific training is for this rating and what I can expect in the field once I am assigned to my Marine unit. I have read many conflicting reports as to where training will take place (I know "A" School is at Great Lakes, IL, however I am confused as to where "C" School will take place. I have heard Camp Pendleton, Camp Lejeune or a Camp in TX). As to the "what to expect in the field" element of the question, is it more likely that I will be in a field hospital on the front lines, or will I actually be in the bush with the Marines doing recon or being involved in other combat situations?
