 Parker later gave interviews about the ordeal the family went through with Harry's injuries, calling the experience "foul".Later the same year, Parker himself deployed to Afghanistan on a twelve-month tour, becoming the commander of the British forces in the country and deputy commander of the International Security Assistance Force (ISAF), second in command to American General Stanley A. McChrystal.In June 2010, McChrystal was relieved of his command of ISAF by President Barack Obama, leaving Parker as acting commander of ISAF for just over a week until General David Petraeus was confirmed as the new commander.
