Can anyone provide advice to someone considering a VTIP to FA 30- Information Operations?

Not really, I am FA30, but I am also RC, which is a whole different beast. Your best bet is going to be to find an AC FA30 and ask them for some guidance. Some thoughts follow.

The vast majority of FA30-specific jobs for Officers are going to be some version of a staff job.

Since the last iteration of 3-13, IO (or now I&I) has gone from being primary staff to being part of the 3. I agree with this change, but it changes your visibility.

Speaking of iterations of 3-13, right now doctrine seems to change faster than some people change socks. I'm not sure I know what an FA30 will be called on to do over the next 5-10 years is set.

I think remaining Signal will be a more STABLE career path. I also wouldn't be surprised if FA30 ultimately gets rolled up under the Signal branch - that would be congruent with the Navy and AF approach.

I'm not a FA30 but I work for a one. Just keep doing your research. If you go that route and don't like it, you might get stuck in it for the rest of your career. I would carefully review all branches/FAs that you qualify for in the next VTIP.

Look up officers in that MOS and reach out. You're more likely to get better information by reaching out rather than asking open-endedly. Come with specific questions. Good luck!
