Camp Kilmer is a former United States Army camp in Central New Jersey that was activated in June 1942 as a staging area and part of an installation of the New York Port of Embarkation. The camp was organized as part of the Army Service Forces Transportation Corps. Troops were quartered at Camp Kilmer in preparation for transport to the European Theater of Operations in World War II. Eventually, it became the largest processing center for troops heading overseas and returning from World War II, processing over 2.5 million soldiers. It officially closed in 2009.
