trauma

All, I take my first NREMT-P in a little more than a week. I have taken exams from varying sources (school's program, MedicTests, etc) but I am struggling a bit with the trauma portion. I am consistently scoring just below standard. I have primarily focused ITLS review and used ATLS...

If someone could enlighten me I've been doing my reaserch but have found little info on what SAR corpsman do (I know the basics...), I guess I'm just confused if they work more for civilians or more in the combat side? All info is appreciated thanks.

I have done an intro but real quick, I am an EMT-B volunteering at hospitals when I can. I want to become a Emergency Room Physician (DO but I hear DO's get shafted on rotations) as a civilian. Also I am college student going for Bachelors in Biochem. I have completed A&P I and am in A&P II now...
