If he sticks with it there is virtually no limit to the doors of opportunity it opens.
My nephew graduated from a TOP TIER school on a full ride scholarship because of it. Cost savings was more than $200,000 easily. He had to work hard and study and keep his nose to the grindstone. But he has a very specialized degree in high demand and after he completes his service obligation in the near future if he decides to get out according to BLS - Bureau of Labor Statistics - data based on his job experience and expertise he will make a salary of approximately $150,000 per year. Not too shabby a return on investment for getting involved in JROTC in my opinion.
