Military Science 3
Also known as ROTC Summer Camp Training (RSCT), Mil Sci 3 is taken by Third Class Army ROTC cadets in their respective regions to enhance their military proficiency and physical condition. The 3Cl cadets of UP ROTC, along with the 3Cl cadets of the other Army ROTC in the National Capital Region (NCR), take up Mil Sci 3 under the NCR Regional Community Defense Group (NCRRCDG).
