Chris Byrne, from Houston, TX, falls to hug his service dog Eagle, after trainer Kristy Greenwood, from Lady Lake, passes Eagle off to him at the Patriot Service Dog Graduation, June 15, at American Legion Post. Byrne served two tours in the infantry. Byrne first tried to commit suicide after he was sexually assaulted during basic training, "I didn't die so I guess I'm supposed to be here." After surviving a mortar attack in Iraq, he says something changed inside him. After completing his first tour Byrne suffered from PTSD. "I started having flashbacks, I was trying to sleep but I would just sweat and I could smell dust." Byrne says the only thing he knew to do was return to war. "I became an alcoholic and I re-enlisted." During his second tour and while team lead, Byrne lost three soldiers to IED attacks, "I broke, I lost my soldiers and I started having homicidal thoughts." Byrne didn't finish the tour. "The hardest thing is having kids and you don't know how to tell them" Byrne said, "This is the first time they know daddy needs some help."
