Get LinkedIn premium for a year (free for veterans, probably current mil, too) and do LinkedIn Learning. Earn your PMP, Green Belt, A+ and several other credentials for the cost of the test. Look at jobs and see what skills they want and find a certification that proves you have those skills. You’re probably more capable than most civilian applicants but good luck proving it with your resume.
AF has an e-learning app on the portal with many of the same topics but LI Premium has better delivery.
