Operation Anaconda took place in early March 2002 in which the United States military and CIA Paramilitary Officers, working with allied Afghan military forces, and other North Atlantic Treaty Organization (NATO) and non-NATO forces attempted to destroy al-Qaeda and Taliban forces. The operation took place in the Shahi-Kot Valley and Arma Mountains southeast of Zormat. This operation was the first large-scale battle in the United States War in Afghanistan since the Battle of Tora Bora in December 2001. This was the first operation in the Afghanistan theater to involve a large number of U.S. conventional (i.e. non-Special Operations Forces) forces participating in direct combat activities.
