The President of the United States of America takes pride in presenting the Silver Star (Posthumously) to Corporal Jacabo Luis Martinez (MCSN: 611696), United States Marine Corps, for conspicuous gallantry and intrepidity while serving with Company F, Second Battalion, First Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 9 June 1951. Manning his post in the company defensive perimeter in the vicinity of Yanggu during the hours of darkness, Corporal Martinez spotted an enemy group attempting to infiltrate the sector and immediately sounded the alarm. Fearlessly dashing through intense hostile fire to take over and put into action the point machine gun after its operator was wounded, he skillfully manned the weapon despite a heavy barrage from enemy small arms and automatic weapons and contributed materially to the infliction of many casualties and to the disruption of the attack. Remaining steadfast at his strategic post, he was struck by enemy fire and fell mortally wounded. His skilled marksmanship, courageous initiative and indomitable fighting spirit reflect great credit upon Corporal Martinez and the United States Naval Service. He gallantly gave his life for his country.
