29,000 contractors versus 9,000 U.S. troops remain in Afghanistan:
Even as early as the middle of 2011, when there were still many U.S. troops in Afghanistan, they were outnumbered by private contractors. The number of private contractors peaked in 2012 at more than 117,000 while there were around 88,000 U.S. troops in Afghanistan. Almost 23 percent of contractors worked as supplementary security personnel. A whopping 70 percent were actually foreign nationals that received money from U.S. companies and agencies.
