Around 100,000 government contractors were working in Iraq in 2006. The volume of private conractors rivals the 140,000 U.S. soldiers in the country. It's dangerous work; some 650 contractors have died there. They do a lot of the jobs the military used to do, everything from providing security and interrogating prisoners to cooking meals for the soldiers. They work for military contractors like KBR and DynCorp International, which are helping train the Iraqi police force. This is the largest contingent of civilians ever operating in a battlefield environment, and there's been no congressional oversight or accountability. That should change with the Democrats taking over the investigative committees on Capitol Hill. The abuses may be just waiting to be uncovered.
