US President Barack Obama and First Lady Michelle Obama leave a memento as they walk through the Warriors Walk, a tribute to the 441 fallen service members who died in Iraq and Afghanistan assigned to or attached to the Third Infantry Division at Fort Stewart in Hinesville, Georgia, April 27, 2012, prior to Obama signing an Executive Order to help US service members and their families make informed decisions about education and to protect them from deceptive targeting by educational institutions. Each fallen service member is honored with a plaque and an Eastern Redbud tree. AFP PHOTO / Saul LOEB (Photo credit should read SAUL LOEB/AFP/GettyImages)
