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 Reuben A. Carr, United States Army Air Forces, for gallantry in action while serving with the 22d Material Squadron, SEVENTH Air Force, during the Japanese air attack on the Island of Oahu, Territory of Hawaii, on 7 December 1941. With disregard for his personal safety, Sergeant Carr volunteered to man a machine gun whose crew had been killed. Sergeant Carr then immediately set forth under continued fire to the dismantled gun, putting it in action, and continued to deliver an effective, accurate fire upon the Japanese aircraft throughout the entire raid. The bravery, coolness and good judgment displayed by Sergeant Carr on this occasion, reflects great credit upon himself and the military service.
