Freeman was killed by a sniper's bullet on Aug. 7, 2009, northeast of Kabul, Afghanistan. Lisa Freeman says, "I walk around this country and look in faces that don't even know we're at war anymore. People that are going about their everyday lives, not realizing that they've been kept safe by this amazing group of young men and women who have been willing to sacrifice so much."
