The best advice I can give to those who are about to become veterans is to take your transition as seriously as any mission you carried out in the military. Identify your objective, and develop a plan to achieve it. Do your research, understand everything you have to offer a company, and find mentors who can help you through the process. Then execute.
It's not easy coming home from war. I wondered why any employer would have a need for a Marine sniper. But then I thought about the other skills I bring to the table -- teamwork, managing personnel in challenging circumstances, advanced technical skills. These are traits no one teaches better than our military.
