How many Security 'Contractors' in the 'Stan?

Well, in this article about lewd and deviant behavior committed by security guards for the US Embassy in Kabal.

The charges come as the number of contractors in Afghanistan eclipses the number of American troops deployed there. The Congressional Research Service reported Tuesday that there are roughly 68,200 contractors in Afghanistan, representing 57 percent of all American personnel there.
"This apparently [represents] the highest recorded percentage of contractors used by DoD in any conflict in the history of the United States," the CRS report said.
As of March, when CRS assessed the data, there were about 57,000 American troops in Afghanistan, but by fall there should be about 68,000.

So the US is paying a lot of money for sub-standard 'contractors' that actually outnumber US troops on the ground.  This is what it looks like when you go for phony 'efficency' rather than effectiveness.
