He served and led Marine commandos for nearly a decade while earning two Bronze Stars for heroism in Afghanistan and in combat against Islamic State fighters in the Middle East.
It was a revered career and selfless service Marine Raider Gunnery Sgt. Scott A. Koppenhafer ultimately paid for with his life.
Koppenhafer was killed Saturday while supporting and advising an Iraqi security forces mission in Ninewah province, Iraq, according to military officials. The Wall Street Journal reported that the military is investigating whether Koppenhafer was struck by Iraqi or U.S. forces.
