The President of the United States of America takes pleasure in presenting the Silver Star to Colonel John Calvin Munn (MCSN: 0-4273), United States Marine Corps, for conspicuous gallantry and intrepidity as Commanding Officer of Marine Aircraft Group THIRTY-ONE in action against enemy Japanese forces on Yontan Airfield, Okinawa, Ryukyu Islands, on 12 April 1945. Exposed to hostile artillery shells falling nearby and to aircraft bombing and strafing attacks, Colonel Munn successfully launched the dawn patrol, using the only existing communication facilities in an exposed tent and, despite the continued enemy barrage, efficiently maintained control of the field, thereby contributing materially to the success of this operation. His outstanding courage, devotion to duty and leadership were in keeping with the highest traditions of the United States Naval Service.
