The President of the United States of America takes pleasure in presenting the Silver Star to Sergeant Vincent E. Mosco (MCSN: 658095), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as Chief of a Howitzer Section of Battery H, Third Battalion, Eleventh Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea early on the morning of 7 December 1950. During a heavy and accurate hostile mortar, automatic weapons and small arms attack on his battery, Sergeant Mosco skillfully directed the positioning of his gun in a strategic location from which effective fire could be delivered on the enemy as they were assembling for a close-in assault on his unit. On one occasion during the engagement, when his gun section was depleted by casualties, he joined another Marine in loading and firing his piece at point-blank range and, as a result of his firing accuracy, was responsible in great measure for repelling the attack with heavy casualties to the enemy. His outstanding courage, initiative and indomitable devotion to duty reflect great credit upon Sergeant Mosco and the United States Naval Service.
