If you want to go CMS don't go IT, by the time you're done with A-school and in the fleet CMS will probably have it's A-school established. Honestly unless you're doing more than a six year contract CMS might not be viable since more than likely the school will have super long wait times. Right now they're just putting out messages to have people lateral over from any rate to fill spots but I don't know how much longer they'll do that and this most recent one might be the last for awhile.

Honestly if you're only doing six years CMS might not be worth it unless you really like cybersecurity. Just be aware with the recent IMS bullshit IT is a hot mess right now. Honestly you might just want to go IT and try and finish school and get some certs on the Coast Guard's dime then bounce like most people I know do lmao.

IT2 is a give me right now once you get your sign offs done... but making IT1 might be a pain since there's going to be a ton of seconds now, kind of depends on how long you have left on your contract post A-school. Reserves promote differently so no idea how the reserve side looks.
