The Missing Guards

About 20,000 private security contractors support the U.S. military in Iraq, guarding convoys, installations and sometimes the military itself. Crescent Security Group, one of 177 private security firms in Iraq, closed within months of an attack on one of its convoys last November. Four American guards in the convoy were kidnapped and are still missing.
