Servicemen relax atop the wreckage of a tracked amphibious landing vehicle (LVT) left stranded on a Pacific beach during World War II. Such vehicles, commonly called Amtracs, ferried troops and supplies from ship to shore during island-hopping campaigns; damaged or destroyed examples like this one were often left in place after fighting had moved inland, becoming both battlefield debris and, for off-duty troops, informal gathering spots.
