Naval absentee collection unit

The Naval Absentee Collection Unit (NACU) was established during World War II as part of the United States Navy's efforts to maintain discipline and accountability among its rapidly expanding ranks. Its primary mission was to locate, detain, and process naval personnel who were absent without leave (AWOL) or deserters, ensuring the return of critical manpower to active duty. Operating in coordination with military police and civilian law enforcement, the NACU maintained records and conducted investigations across both domestic bases and overseas stations. Over time, the unit's role was absorbed into broader naval law enforcement and personnel management functions, reflecting changes in military justice and administrative procedures.
