It’s occupation by another name. Pratap Chatterjee explains:
The number of contractors in Afghanistan is likely to increase significantly in the next year as the Obama administration pulls back some of the extra 68,000 troops that it has dispatched there since January 2009.
Typically, the U.S. pays one contractor to support every soldier that has deployed to Afghanistan and Iraq. The ratio of contractors to troops increases dramatically during a military surge as well as during a drawdown, and often stays higher than troop levels when military numbers are low, i.e. down to 30,000-50,000.
The reason is simple — the military needs extra workers to build new bases as well as to shut them down. Just like a hotel or restaurant, a military base also needs a minimum number of people to do the basics like janitorial or food service work. And as troops withdraw, U.S. diplomats are likely to hire extra security contractors as they are doing now in Iraq.
Using a range of 1.3 to 1.4 (based on what Afghanistan needed before the surge and Iraq needed after the drawdown), I would project that if the Obama administration draws down to 68,000 troops in Afghanistan by September 2012, they will need 88,400 contractors at the very least, but potentially as many as 95,880.
