You can engage in our online training and certification at any point in your military career or civilian role. Since every online course can be retaken, there is no reason why you couldn't become a Subject Matter Expert (SME) while enlisted, and then retake those courses again, and others, once you transition to a civilian role. It is up to each veteran to make that decision. You could also apply, get accepted, and while enlisted have your spouse take courses. TrainOurTroops allows the spouse of a veteran to perform training as well. If you're a veteran already in a civilian job you could take any or all of our courses to assist in your career.
