I'm a junior in high school and I am absolutely positive I want to become an officer in the Army through AROTC. I have done a lot of research and still have some questions. So, when I go through ROTC and graduate I want to go into the infantry branch of the Army. Is infantry difficult to get it into and how does the Army choose who gets to go in which area of the Army, is it based on how you do in college and ROTC. How can I improve my chances of getting in the branch I want?
