Now the Alabama National Guardsman is trying to get his life back together after a year that's brought a double-whammy of misfortune.
Williams' unit came under mortar fire in Kandahar and he suffered a concussion when a shell struck just a few yards away. The next morning, he awoke to headaches and dizziness and was diagnosed with a concussion and vertigo.
While back home in the United States, Williams' home in Pleasant Grove, Ala., was destroyed by one of more than 60 tornadoes that plowed across the state April 27.
