You won't automatically be an officer. You would have had to be in ROTC for 2 or 3 years. If not, you would have to go to OCS (Officer Candidate School) once you're in the military. A college degree doesn't translate into becoming an instant officer unless you are a doctor or a lawyer.
He can get OCS in his contract if he has a college degree.
You can't become a doctor with a college degree.
