The 2004 counterinsurgency campaign in Afghanistan was historic. Service personnel of general purpose, special operations, coalition, and irregular forces worked in unison to defeat the insurgency in a country stricken by war. Their unwavering trust, cooperation, close integration, collaborative planning, and nested execution were in many cases, textbook. In recognition of their professional effort, this case study captures many of the lessons learned in their planning and operations. Success in Afghanistan also came from the determination of millions of Afghans who were supported by these gallant sailors, soldiers, Marines, and airmen.
