"For extraordinary heroism and distinguished service in the line of his profession as Commanding Officer of the Heavy Cruiser U.S.S. PENSACOLA (CA-24), in action against enemy Japanese forces off Iwo Jima, Volcano Islands, on 17 February 1945. When a hostile heavy-caliber shore battery repeatedly hit his ship, causing extensive damage, fire and many casualties, Captain Mullinnix replied with vigorous, heavy and accurate counter-fire which silenced the enemy battery and, with cool courage, directed the rapid completion of emergency repairs, enabling the ship to remain on station and carry out its assigned mission. His aggressive fighting spirit and gallant devotion to duty were in keeping with the highest traditions of the United States Naval Service."
