That is, there was no outcry whenever contractors were called up and deployed, or even killed. If the gradual death toll among American troops threatened to slowly wear down public support, contractor casualties were not counted in official death tolls and had no impact on these ratings. By one count, as of July 2007, more than 1,000 contractors have been killed in Iraq, and another 13,000 wounded. (Again, the data is patchy here, with the only reliable source being insurance claims made by contractors' employers and then reported to the U.S. Department of Labor.) Since the troop "surge" started in January 2007, these numbers have accelerated -- contractors have been killed at a rate of nine per week. These figures mean that the private military industry has suffered more losses in Iraq than the rest of the coalition of allied nations combined. The losses are also far more than any single U.S. Army division has experienced.
