Captain Stephen "Shanghai Six" Machuga is a former Army Infantry/Military Intelligence officer and Airborne Ranger, having spent the majority of his service at Fort Bragg with the 82nd Airborne Division. In 2003, he deployed to Iraq with 2nd Infantry Division and whittled through the seemingly endless 13-month deployment with the help of video games. Captain Machuga left the service in 2006, where he spent 10 years in Washington DC as a government counter-terrorism analyst across a variety of agencies, doing charity work on the weekends. Upon realizing that no one in the gaming space was taking care of veterans, he founded Stack Up, a military gaming charity specifically supporting US and Allied veterans with gaming.
