Hi! I am an incoming freshman physics and computer science major and was wondering about joining Army ROTC. I absolutely love the idea of getting training during college and I believe that it would be a great program for me, especially with the scholarship (my college would be too expensive to pay off without significant loans). However, I had qualms about the military service afterward. I am planning on pursuing a doctorate so, for my service, I would be part-time in the Army Reserves/National Guard for eight years and do not want to go straight into Active Duty. However, I am well aware that there is a decent chance (50%?) that I would be deployed full time maybe for a couple months or so which I am fine with (but an over 1-year deployment might be problematic). If I do get deployed full time, I would be happy to serve my country but I would rather work on something like nuclear missile defense research or programming UAVs. I especially do not want to be deployed to other countries for combat. What are my chances of being called into Active Duty and how much would it disrupt my doctorate or other plans? Also, would the Army Reserves or National Guard be a better option for me? Finally, should I do ROTC?
