Tillman did not have to join the Army and no one would have criticized him if he did not. Tillman’s decision brings to mind the same choice made by James Robert Kalsu, one of only two NFL players to die in the Vietnam War. In 1968, Kalsu played his rookie season for the Buffalo Bills and was a budding star. He belonged to the Reserve Officers Training Corps (ROTC) and was told his duty status could be indefinitely postponed while he was in the NFL. Since the war was then expected to wind down, Kalsu knew that postponing his service would mean avoiding exposing himself to combat. Instead he asked to serve, was sent to Vietnam in 1969 and died there in a mortar attack in 1970 at the age of 25. No one would have criticized Kalsu if he had not gone to Vietnam. He went because he thought it was right.
