Thank you for your service. With your experience, it should help you become a part of flight team. Most people where I work have ICU experience. Start doing pre req's for your BSN of you can, or see if the military can help you figure out what may transfer to your school of choice, and once you are done with school and have your license, start talkign with murse recruiters. It may seem like a long road, but with your commitment to service, you can certainly achieve your goal!
