Middle Eastern companies, including Kulak Construction Co. of Turkey and Projects International of Dubai, supply labor from Third World countries to KBR and other U.S. companies for menial work on U.S. bases and rebuilding projects. Foreigners are used instead of Iraqis because of fears that insurgents could infiltrate projects.
KBR is by far the largest employer of Americans, with nearly 14,000 U.S. workers. Other large employers of Americans in Iraq include New York-based L-3 Communications, which holds a contract to provide translators to troops, and ITT Corp., a New York engineering and technology firm.
The most controversial contractors are those working for private security companies, including Blackwater, Triple Canopy and Erinys. They guard sensitive sites and provide protection to U.S. and Iraqi government officials and businessmen.
Security contractors draw some of the sharpest criticism, much of it from military policy experts who say their jobs should be done by the military. On several occasions, heavily armed private contractors have engaged in firefights when attacked by Iraqi insurgents.
Others worry that the private security contractors lack accountability. Although scores of troops have been prosecuted for serious crimes, only a handful of private security contractors have faced legal charges.
The number of private security contractors in Iraq remains unclear, despite Central Command's latest census. The Times identified 21 security companies in the Central Command database, deploying 10,800 men.
However, the Defense Department's Motsek, who monitors contractors, said the Pentagon estimated the total was 6,000.
Both figures are far below the private security industry's own estimate of about 30,000 private security contractors working for government agencies, nonprofit organizations, media outlets and businesses.
Industry officials said that private security companies helped reduce the number of troops needed in Iraq and provided jobs to Iraqis -- a benefit in a country with high unemployment.
"A guy who is working for a [private security company] is not out on the street doing something inimical to our interests," said Lawrence Peter, director of the Private Security Company Assn. of Iraq.
Not surprisingly, Iraqis make up the largest number of civilian employees under U.S. contracts. Typically, the government contracts with an American firm, which then subcontracts with an Iraqi firm to do the job.
