For valorous achievement as a Fire Team Leader in the vicinity of the city of Al Fallujah, Iraq in support of Operation Inherent Resolve. On May 9th, 2018, in response to an enemy attack with mortars and automatic rifle fire, Sergeant Koch, without regard for his own safety, moved outside the secured perimeter to better adjust artillery against the enemy while leading and controlling his own fire team. On that date, the platoon came under a sustained enemy mortar barrage and ground attack. Reacting immediately, Sergeant Koch moved outside the security perimeter and placed a heavy volume of accurate suppressive fire on enemy positions while calling for artillery fire. His bravery and immediate action was a major factor in repelling the attack and saved the lives of all members in the camp. His performance in combat reflects great credit upon himself, the 113th Infantry Regiment and the United States Army.
