The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star (Army Award) to Sergeant Arnold A. Perri (MCSN: 657099), United States Marine Corps, for conspicuous gallantry and intrepidity in action against an armed enemy near Yŏngsan, Korea, on 5 September 1950. On this date, Sergeant Perri was an 81-mm. Mortar Platoon Observer attached to Company A, First Battalion, Fifth Marines, First Marine Division (Reinforced). Sergeant Perri, without orders moved to an exposed position in front of the head rifle platoon and by doing so exposed himself to intense small arms fire. He took the SCR 300 radio from his radio man due to the danger of more than one man moving to the exposed position. From this position he was able to bring fire to bear against enemy positions which were continually threatening Company A's position. A short time later, Company B, First Battalion, Fifth Marines, which was on the right, received a strong counterattack and it was partly through Sergeant Parri's accurate and well-placed mortar fire that the attack was repulsed. Sergeant Perri remained in his exposed position for approximately three hours being continually exposed to heavy enemy fire in order that he could fire on targets that were a continual source of danger to his Company. The gallantry displayed by Sergeant Perri reflects great credit on himself and the United States Naval Service. Headquarters, VIII U.S. Army, Korea (EUSAK), General Orders No. 151 (November 1, 1950). Entered Service From California.
