Greene is killed while in Kabul, Afghanistan, by a man dressed as an Afghan soldier. It is believed Greene was not targeted but that the gunman opened fire and he was one of the 15 that were hit. This was his first deployment into the war zone and he was preparing troops for when they would be sent back at the end of this year. Greene is the highest ranked officer killed in combat since the 1970 Vietnam war and had been in the army for 34 years. General Ray Odierno:
It is service and sacrifice that define us as an army. Our priority right now is to take care of the families, ensuring they have all the resources they need during this critical time.
