The President of the United States of America takes pleasure in presenting the Silver Star to Staff Sergeant John L. Arnold (MCSN: 561886), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Platoon Sergeant of Company G, Third Battalion, Fifth Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 28 November 1950. With the platoon subjected to withering hostile automatic weapons, hand grenade and small arms fire during an attack against a strongly defended enemy hill position which posed a serious threat to the battalion post, Staff Sergeant Arnold bravely moved through the devastating hostile barrage to assist in the maneuvering of the men, shouting words of encouragement and skillfully directing their fire. Unhesitatingly assuming command of the squad when the platoon leader became a casualty, he spearheaded a determined assault on the position, completely routing the enemy and securing the strategic ground. Subsequently, when the hostile force regrouped on an adjacent ridge, he again led his men forward in the attack until he fell seriously wounded and was forced to submit to evacuation. By his courageous leadership, resolute determination and indomitable fighting spirit, Staff Sergeant Arnold contributed materially to the success of his company and served to inspire all who observed him, thereby upholding the highest traditions of the United States Naval Service.
