Besides CID, what other MOS can I pursue if I want to become a Warrant Officer?

How is it not helpful? It has every feeder MOS listed. It's very simple, you must be in an MOS identified as a feeder MOS to be eligible for a warrant MOS. Plus you'll need at least a 110 GT and a secret clearance, and usually ALC for that MOS.
If you can't figure it out from there then you probably don't qualify as a Technical Subject Matter Expert in that field.

Have you googled that question?

The WO Recruiting web page has all of the information on what MOS allows you to go into what WO MOS. Some of them cross over (all MOS's can go pilot, etc) whereas some other ones are more restrictive. For instance as a 35F i can stay intel, go pilot, or IT if i have experience (which i don't) so only have pilot and intel for me.
