In this second half of our interview with retired U.S. Navy SEAL Mark Greene, we will focus on Lt. Greene's deployments - first to Iraq and then to Afghanistan.And he discusses his work helping veterans transition from the military back into civilian life.

Greene shares what sound was so common in Iraq that it served as an alarm clock just about every day. He also details the role his SEAL team played on that deployment.

Greene also takes us along on multiple deployments to Afghanistan. He explains why he really couldn't put his sniper skills to use there and what it was like operating in Afghan villages. He also tells us about the firefight there that he describes as "mayhem."

Finally, Greene tells us about his very difficult transition to civilian life, what helped to set him on the right path, and how he is helping other veterans thrive after leaving the military.
