Gen. McChrystal on battling ISIS, "Team of Teams" military strategy
With modern warfare, Gen. Stanley McChrystal had to redefine counterterrorism strategy while leading the Joint Special Operations Task Force in Iraq and Afghanistan.

McChrystal joins "CBS This Morning" to discuss his new book, "Team of Teams: New Rules of Engagement for a Complex World."
