Almost every naval officer will have contact with an administrative investigation (commonly referred to as a "JAGMAN" investigation) during their military career, either as an investigating officer or as a convening authority. The basic regulations governing such investigations are contained in the Manual of the Judge Advocate General (JAGMAN). The primary purpose of an administrative investigation is to provide the convening authority and reviewing authorities with information regarding a specific incident which occurs in the Department of the Navy. These officials will then make decisions and take appropriate action based upon the information contained within the investigative report.
