So the cool thing about AFROTC is that there are a variety of majors considered technical that are not listed on the AFs website. For instance I study Digital Media Design, which the AF considers technical because of the heavy programming emphasis. I have a friend that studies Biotechnology, which is also considered technical.
Note that not all technical majors have 5 year scholarship benefits; generally this is reserved for engineers. My degree is a 4 year benefit.
The best course of action is to call the detachment you wish to attend; they can look up the degree to see if it is technical or not.
