Alejandra Fernandez-Morera of the Scripps Howard News Service found there are significant invisible casualties of the Iraqi occupation. Almost 505 civilian contractors have died in Iraq since the beginning of the war. "Another 4,744 contractors have been injured, according to insurance claims by 209 companies on file at the Department of Labor." The investigation found that neither the Pentagon nor American corporations who hire contractors to support the U.S. military in Iraq will identify the Americans and foreign nationals who have died, citing privacy and security reasons. The unnamed civilians have become a significant part of the cost of the Iraqi occupation, accounting for at least one-sixth of U.S. fatalities suffered. Because the Pentagon has outsourced thousands of jobs, American contractors have become a new kind of Unknown Soldier.
