The U.S. Army is conducting a review of the reports it has given families on the deaths of soldiers killed in combat in Iraq and Afghanistan.
Army officials announced on Friday that they are preparing to request that all unit commanders submit lists of their combat deaths so accounts of those deaths can be checked for accuracy.
Spokesmen said Friday that about 500 of some 1,700 Army deaths in Iraq and Afghanistan have been checked already, and only a tiny fraction were found to have inaccuracies.
The review follows the high-profile case of former professional football player Pat Tillman who was killed by friendly fire. The Army initially told Tillman's family that he died as the result of an enemy ambush.
Some information for this report was provided by AP and Reuters.
