Going to the Army for radiology ,what else is needed to become a radiologist ?

I am getting into a radiology program in the Army. I am sure this will only teach me the basics and I will not earn any kind of medical degree. However once I complete the Army’s training, I think I will be some sort of technician? I will be in the Army for 5 years so I have time to take college courses while I am enlisted. What kind of classes should I take that will ultimetly help me become an M.D.? I know I will still have to complete a residency when I get out of the Army. I just want to know the best steps to take while im still in the Army.
