The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Corporal Jason S. Clairday, United States Marine Corps, for extraordinary heroism as Fire Team Leader, 1st Squad, 2d Platoon, Company K, Third Battalion, Fifth Marines, Regimental Combat Team 1, FIRST Marine Division, during Operation IRAQI FREEDOM on 12 December 2004. While conducting a security sweep in the Askari District of Al Fallujah, a platoon-sized insurgent force engaged 3d Platoon. Corporal Clairday immediately repositioned his men and jumped a four foot gap three stories up onto the roof of the enemy stronghold where a mortally wounded Marine lay, isolated by the enemy. After throwing several fragmentation grenades, Corporal Clairday fiercely led the attack into the house. He was immediately hit with enemy AK-47 rifle fire in both legs and fell into the kill zone. Under heavy enemy fire, he continued to aggressively engage the enemy while extracting himself from the doorway. Without regard for his own wounds, he rejoined the squad making entry and entered the house a second time. Once inside, he took control of the stack and repositioned himself in the front while suppressing the enemy using fragmentation grenades and his rifle. Again, without concern for his own safety, Corporal Clairday led the Marines into the room where he single-handedly attacked the insurgents and received mortal wounds. His courageous actions enabled reinforcing assault elements to destroy the insurgent position. By his outstanding display of decisive leadership, unlimited courage in the face of heavy enemy fire, and utmost devotion to duty, Corporal Clairday reflected great credit upon himself and upheld the highest traditions of the Marine Corps and the United States Naval Service.
