Petty Officer 2nd Class Arthur Sacdana prepares a wreath donated by the Consulate General of Japan for display during upcoming Pearl Harbor Day events aboard the USS Arizona Memorial. The wreaths serve as a tribute to service members killed during the Dec. 7, 1941 attack on Pearl Harbor. The theme of this year's historic commemoration, "Pacific War Memories: The Heroic Response to Pearl Harbor," emphasized the brave efforts of those who fought at sea, on land and in the air to turn the tide in the Pacific. More than 2,000 guests and the general public joined service members, Pearl Harbor survivors and their families and friends for the annual observance.
