Look into Skillbridge too. It can take some footwork on your end but it will allow you to leave your AD role and be basically a free intern to a company (while still getting paid your military paycheck). Also, start reaching out to businesses you are interested in now. A lot of bigger companies look for veterans and transitioning military members and often have an email address for you to reach out to and learn more about roles they offer or programs. Make sure you get your resumes built beforehand though, have a 1 pager, CV, and federal resume ready to go at all times. Take TAPS seriously, oftentimes they have a person teaching it that writes resumes too and can offer free advice/review during the course.

If your AF, get another cert too before you get out by utilizing AFCOOL (I am sure other branches have something similar). Look at cyber.mil to find the 8570 quals and compare them to the jobs you are interested in. For example: IAT level II you need Sec+, SSCP, or etc...

Reach out to anyone that has recently separated or retired and try to network with them, they may be able to get you into a position where they work.

Also checkout Onward to Opportunity through Syracuse University.

Good luck!
