The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Master Sergeant Edward Fristock (MCSN: 278367), United States Marine Corps, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as a Gunnery Sergeant of Company D, Second Battalion, Fifth Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces near Waryong-ni, Korea, on 7 June 1951. When a hail of enemy automatic-weapons fire resulted in the separation of two squads from their platoon during a vigorous company assault against fiercely defended hostile positions, Master Sergeant Fristock efficiently reorganized the two units and boldly led them up the hill while the enemy continued to sweep the area with deadly rifle, machine-gun and grenade fire from well-camouflaged bunkers. Risking the danger from bursting grenades and shellfire, he fearlessly directed a vigorous attack on the hostile emplacements, shouting words of encouragement and pointing out spots of cover to his men. Spearheading the assault as he neared the top of the enemy ridge, he was hit by hostile fire and fell mortally wounded. His intrepidity, courageous leadership and indomitable fighting spirit inspired the remaining men to sweep through the hostile positions and completely rout the enemy, thereby reflecting the highest credit upon Master Sergeant Fristock and the United States Naval Service. He gallantly gave his life for his country.
