The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to Sergeant Raymond Arviso (ASN: 38011540), United States Army, for gallantry in action while serving in the 813th Tank Destroyer Battalion, in action against the enemy on 26 March 1945 in Germany. When Sergeant Arviso, tank destroyer gun commander, observed enemy troops firing on a friendly medical quarter-ton truck, he immediately called for high explosive fire on the enemy position. Despite heavy mortar fire in the area, he unhesitatingly manned the machine gun on top of the destroyer turret and from this exposed position fired on the enemy. Although the bulk of enemy fire was immediately directed on the tank destroyer, the medical vehicle was not able to escape immediately, and Sergeant Arviso continued his fire. One mortar shell landed so close to the destroyer as to a blow Sergeant Arviso from his position. Disregarding painful injuries, he crawled back to his position and immediately resumed fire. Another mortar shell again wounded him severely, but his continued fire enabled the vehicle to make its escape. The courage and tenacity of purpose displayed by Sergeant Arviso reflect high credit on himself and the armed forces of the United States.
