FILE - In this November 1943 file photo released by the U.S. Marine Corps., smoke is seen rising from the wreckage of Japanese defense installations as U.S. Marines crouch for cover during the invasion of Tarawa atoll, Gilbert Islands. Some 560 U.S. servicemen are unaccounted for from the Tarawa battle. There are still 78,000 U.S. troops missing from World War II alone, including 35,000 the military believes it can recover. The rest are entombed on sunken ships or otherwise lost at sea. Thousands more are missing from the Korean and Vietnam wars. less
