Is enrolling in Army ROTC the same as joining the Army? Once a student starts taking ROTC courses, is he/she obligated to join the Army?

Young adults must serve as Officers in the Army after graduation if they have received an ROTC scholarship, OR if they have enrolled in the ROTC Advanced Course. Enrolling in the ROTC Basic Course (the first two years of college) does NOT obligate someone to serve unless they have also received a scholarship.
