Felony criminal investigations are the cornerstone of the NCIS mission. NCIS is the investigative entity within the Department of the Navy (DON) responsible for major criminal investigations involving Navy and USMC equities, service members, and affiliated civilian personnel. NCIS civilian Special Agents have the authority to investigate criminal acts in accordance with both the Uniform Code of Military Justice (UCMJ) and established criminal laws under the United States Code (USC) when there is a DON nexus.

NCIS Special Agents initiate and lead criminal investigations when the punishment for the offense is confinement of more than one year in prison; routinely investigating the crimes of homicide, rape, sexual assault, child physical and sexual abuse, burglary and robbery, larceny of government and personal property, and aggravated assault. NCIS also investigates any non-combat death involving a Navy or USMC service member.

Throughout their careers, Special Agents are afforded the opportunity to work criminal investigations in offices located worldwide, in forward deployed environments, and with local, state, federal and international law enforcement partners.
