"The 2.4 million bright, brave, incredibly fit and remarkably talented young Americans who have served in our armed forces since we were attacked on 9-11-01 are all volunteers. As General Petraeus put it during a conversation we had in Afghanistan, 'They all came or stayed, knowing they were going to war.' For more than a decade, these patriots and their loved ones have made extraordinary sacrifices for this country. They embody the classical definition of heroes: those who put themselves at risk for the benefit of others."
