Greg Gangnuss, a civilian member of the Air Force Installation and Mission Support Center, was on a voluntary deployment to Afghanistan as a senior environmental adviser for the Ministry of Defense Advisor Program when a helicopter carrying nine coalition members crashed after striking a cable while landing at the NATO Resolute Support Mission headquarters in Kabul Oct. 11, 2015, killing five people on board. Gangnuss helped rescue four, including Col. Laurel Burkel.
