The President of the United States of America takes pleasure in presenting the Silver Star to Sergeant Matthew Parker, United States Marine Corps, for gallantry in action while engaged in military operations involving conflict with an armed hostile force while serving as Second Squad Leader, Second Platoon, Company I, Third Battalion, Second Marines, Regimental Combat Team 8, SECOND Marine Division (Forward), II Marine Expeditionary Force (Forward) Afghanistan, on 21 May 2011 in support of Operation ENDURING FREEDOM. In Musa Qualah District, an entrenched enemy with small arms, medium machine gun, automatic grenade launcher, and recoilless rifles engaged the platoon. During the attack, enemy fire wounded and incapacitated the platoon commander and a Combined Anti-Armor Team section, a vehicle mobile element, and a sniper team. Under increasing fire, he coordinated the fire and maneuver of his platoon and supporting elements, and repelled the enemy’s attack from three directions. Suffering intense enemy machine gun and recoilless rifle fire, he calmly and precisely coordinated for close air support and High Mobility Artillery Rocket System strikes that destroyed two enemy machine gun positions. Seizing the initiative, he guided supporting fires while directing the platoon’s fires, forcing the enemy to withdraw. Still receiving sporadic enemy fire, he evacuated his casualties and tactically withdrew his force to the closest patrol base. By his zealous initiative, courageous actions, and exceptional dedication to duty, Sergeant Parker reflected great credit upon himself and upheld the highest traditions of the Marine Corps and the United States Naval Service.
