A 2-1/2-ton 6x6, nicknamed "the Duck/' standardized in October 1942, proved to be an extremely valuable piece of equipment. It could operate on land or water and was often used to bring supplies ashore where there were no ports or harbors available for larger craft. Supplies loaded from ships onto the Ducks could unload at the supply dumps, saving the extra handling involved when lighters or similar craft were used. This vehicle could carry approximately 25 men and their equipment or a 5,000-pound payload.
