see url Every military service has its own law enforcement entities to investigate criminal allegations among servicemembers. The U.S. Navy, for example, comprises several investigative arms, each dedicated to a different level of criminal gravity. The role of the Naval Criminal Investigative Service (NCIS) is to handle serious criminal allegations, such as sexual assault, high-dollar larceny, and murder. Criminal Investigation Division (CID) is a division of naval investigations that deals primarily with low-level criminal allegations, or misdemeanor-type offenses, such as fraternization, adultery, and certain order violations.
see Regardless of the service branch or the name of the investigative body, the purpose of these agencies is consistent: to examine criminal allegations fully, using all the investigative tools and resources of the federal government, and produce a written report for the Commanding Officer/General’s review.
