was an Ensign in the Waves. In looking at the geography, if she was stationed near Brooklyn, that would likely be Fort Hamilton (assuming that existed in the early 1940's).

According to it's website:
In the two World Wars, Fort Hamilton served as a major embarkation and separation center. At present, the United States Army Fort Hamilton Garrison is the home of the New York City Recruiting Battalion, the Military Entrance Processing Station, the North Atlantic Division Headquarters of the US Army Corps of Engineers, the 1179th Transportation Brigade and the 722nd Aeromedical Staging Squadron. Fort Hamilton also supports many Reserve and National Guard units. ... Fort Hamilton proudly serves as the Army's Ambassador to the Greater New York Metropolitan Area.

Construction of the Verrazano Bridge in the early 1960's destroyed several historic structures, including Fort Lafayette, which was located near the Brooklyn shore where the bridge tower now rises from the water. But in the same period efforts toward saving the historical heritage of the Narrows increased. Part of the Army's contribution to preserving this heritage is in the Harbor Defense Museum at Fort Hamilton.
