Army Chief of Staff General Ray Odierno said it is not clear why wartime hardships make some soldiers stronger, while others struggle with the effects. He said the Army will do more to address the problem.

　　We will also do everything within our power to investigate every detail, to learn, to adapt and to protect our most valuable resource: the men and women of our U.S. Army, said Odierno.

　　Secretary of the Army John McHugh praised the victims for their bravery, which he said saved many other lives.

　　We may never know how many lives were saved or how many others might have been lost were it not for these heroes. But know this: we are incredibly grateful for their bravery and even more humbled by their selflessness, said McHugh.

　　On Thursday, President Obama joins former presidents Jimmy Carter, Bill Clinton and George W. Bush in the state capital, Austin, to honor the 50th anniversary of the Civil Rights Act. The legislation outlawed racial discrimination in voting, schools, public accommodations, and the workplace.
