A Pentagon investigation will recommend that nine officers, including up to four generals, be held accountable for missteps in the aftermath of the friendly fire death of Army Ranger Pat Tillman in Afghanistan, senior defense officials said. The Defense Department inspector general will cite a range of missteps and inappropriate conduct as the military probed the former football star's death on the battlefront in 2004, said one defense official. The official, who requested anonymity because of the sensitivity of the issue, said it appears that senior military leaders might not have had all the facts or worked hard enough to get the facts of what happened on that day in April 2004.
