Army Chief of Staff Gen. Raymond T. Odierno meets former Army Staff Sgt. Brian Keaton Sr. during the Nationals vs Cardinals game at Nationals Stadium in Washington, D.C., Oct. 10, 2012. Keaton is a combat veteran with multiple deployments to Iraq. He suffers from frequent seizures, and that keeps him from traveling much. He is a patient at Walter Reed National Military Medical Center in Bethesda, Md., and baseball, his life-long love, has aided his recovery.
