Naval Criminal Investigative Service


The United States Naval Criminal Investigative Service is the primary law enforcement agency of the U.S. Department of the Navy. Its primary function is to investigate criminal activities involving the U.S. Navy and U.S. Marine Corps, though its broad mandate includes national security, counterintelligence, counter-terrorism, cyber warfare, and the protection of U.S. naval assets worldwide. NCIS is the successor organization to the former Naval Investigative Service, which was established by the Office of Naval Intelligence after the Second World War.
The vast majority of NCIS personnel are civilian, with half being special agents. NCIS agents are armed federal law enforcement investigators, who frequently coordinate with other U.S. government agencies and have a presence in more than 41 countries and on U.S. Navy vessels. NCIS special agents are supported by analysts and other experts skilled in disciplines such as forensics, surveillance, surveillance countermeasures, computer investigations, physical security, and polygraph examinations.

History

Origins

NCIS traces its roots to Navy Department General Order 292 of 1882, signed by William H. Hunt, Secretary of the Navy, which established the Office of Naval Intelligence. Initially, ONI was tasked with collecting information on the characteristics and weaponry of foreign vessels, charting foreign passages, rivers, or other bodies of water, and touring overseas fortifications, industrial plants, and shipyards.
In anticipation of the United States' entry into World War I, ONI's responsibilities expanded to include espionage, sabotage, and all manner of information on the U.S. Navy's potential adversaries. In World War II ONI became responsible for the investigation of sabotage, espionage and subversive activities that posed any kind of threat to the Navy.

NIS and the Cold War

The major buildup of civilian special agents began with the Korean War in 1950, and continued through the Cold War years. In 1966 the name Naval Investigative Service was adopted to distinguish the organization from the rest of ONI, and in 1969 NIS special agents were reclassified from contract employees and became Excepted Civil Service.
In the early 1970s, an NIS special agent was stationed on for six months. This marked the beginning of the "Deployment Afloat" program, now called the Special Agent Afloat program, which deploys special agents for year-long assignments aboard carrier battle groups and amphibious readiness groups. In 1972, background investigations were transferred from NIS to the newly formed Defense Investigative Service, allowing NIS to give more attention to criminal investigations and counter-intelligence. The 1970s also saw NIS' first female agent, who was stationed at Naval Air Station Miramar, California in 1975.
In 1982, NIS assumed responsibility for managing the U.S. Navy's Law Enforcement and Physical Security Program and the U.S. Navy's Information and Personnel Security Program. Additionally, in 1982, two classes of NIS Special Agents were trained at the Federal Law Enforcement Training Center in Glynco, Georgia, in an assessment of the school's capability to train military investigators. Prior to this and subsequently until 1984, NIS Special Agent Training was in ONI Headquarters in Suitland, Maryland. In 1984, NIS Special Agents began training at FLETC, along with other federal investigative agencies, except for the Federal Bureau of Investigation, the Drug Enforcement Administration, and the United States Postal Inspection Service.
Two months after the October 1983 bombing of the Marine Barracks in Beirut, the agency opened the Navy Antiterrorist Alert Center, a 24-hour-a-day operational intelligence center that issued indications and warnings on terrorist activity to Navy and Marine Corps commands. ATAC was the facility at which Jonathan Pollard was working when he committed the acts of espionage for which he was convicted in 1987. In 2002 the ATAC became the Multiple Threat Alert Center.
In 1985, Cathal L. Flynn became the first admiral to lead NIS. The command took on the additional responsibility of Information and Personnel Security. In 1986, the Department of the Navy Central Adjudication Facility was established and placed under the agency, as the agency was now once again responsible for adjudicating security clearances. DoN CAF renders approximately 200,000 eligibility determinations annually for the Department of the Navy.
In 1991, NIS was responsible for investigating the Tailhook scandal, which involved allegations of sexual misconduct and harassment by Naval and Marine Corps officers in Las Vegas, Nevada. Subsequent to this investigation, and at the direction of the chairman of the US Senate Armed Services Committee, Senator Sam Nunn, the Naval Investigative Service was restructured into the Naval Criminal Investigative Service. The restructuring occurred as a result of perceived lapses in proper investigative technique over the Tailhook scandal, as well as chain of command issues and a lack of civilian oversight in previous investigations. At the time, Senator Nunn stated, "The Navy's whole investigative technique should be under serious question." As a result of the investigation into the Tailhook scandal, the Pentagon's inspector general was sharply critical of NIS leadership, stating that there was a top-down culture showing a lack of cooperation with other authorities in the Navy. By 1992, Acting Secretary of the Navy, Sean O'Keefe, recommended the word "Criminal" be included in NIS's name in order to make clear their investigative function. Ultimately, NIS commander, Rear Adm. Duvall Williams Jr., was forced to retire and NIS was reorganized as NCIS under civilian leadership.

Recent history

In 1992, the NCIS mission was again clarified and became a mostly civilian agency. Roy D. Nedrow, a former United States Secret Service executive, was appointed as the first civilian director and the name changed from Naval Investigative Service to Naval Criminal Investigative Service. Nedrow oversaw the restructuring of NCIS into a Federal law enforcement agency with 14 field offices controlling field operations in 140 locations worldwide. In 1995, NCIS introduced the Cold Case Homicide Unit, the first dedicated federal-level cold case homicide unit. The unit has resolved 61 cases since 1995.
In May 1997, David L. Brant was appointed Director of NCIS by Secretary of the Navy John Howard Dalton. Director Brant retired in December 2005. He was succeeded by Director Thomas A. Betro who was appointed Director of NCIS in January 2006, by Secretary of the Navy Donald C. Winter. Betro retired in September 2009. On September 13, 2009, Deputy Director of Operations Gregory A. Scovel was appointed Acting Director by Under Secretary of the Navy Robert Work. He served concurrently as Deputy Director for Operations until the new Director was selected.

In 1999, NCIS and the Marine Corps Criminal Investigation Division signed a memorandum of understanding calling for the integration of Marine Corps CID into NCIS.
In 2000, Congress granted NCIS civilian special agents authority to execute warrants and make arrests. Virtually all NCIS investigators, criminal, counterintelligence, and force protection personnel are now sworn civilian personnel with powers of arrest and warrant service. The exceptions are a small number of reserve military elements engaged in counter-intelligence support.
A growing appreciation of the changing threat facing the Department of the Navy in the 21st century, culminating with the terrorist bombing of the in Yemen and the attacks on September 11, 2001, led NCIS to transform the Anti-terrorist Alert Center into the Multiple Threat Alert Center in 2002.
NCIS agents were the first U.S. law enforcement personnel on the scene at the USS Cole bombing, the Limburg bombing and the terrorist attack in Mombasa, Kenya.
NCIS has conducted fraud investigations resulting in over half a billion dollars in recoveries and restitution to the U.S. government and the U.S. Navy since 1997. NCIS investigates any death occurring on a Navy vessel or Navy or Marine Corps aircraft or installation. NCIS oversees the Master-at-Arms programs for the Navy, overseeing 8800 Masters-at-Arms and the Military Working Dog program. NCIS's three strategic priorities are to prevent terrorism, protect secrets, and reduce crime.
Current missions for NCIS include criminal investigations, force protection, cross-border drug enforcement, anti-terrorism, counter-terrorism, major procurement fraud, computer crime and counter-intelligence.
NCIS Special Agent Peter Garza conducted the first court-ordered Internet wiretap in the United States.
Jonathan Jay Pollard was an NIS analyst who was convicted of spying for Israel after being caught by NIS and FBI. He received a life sentence in 1987.
On February 14, 2010, Mark D. Clookie became the fourth civilian Director of NCIS, having been appointed to the position by Secretary of the Navy Ray Mabus.
In June 2010, NCIS undertook a major reorganization which created a single Deputy Director position, having previously had two, combination of the Combating Terrorism Directorate and the Counterintelligence Directorate into a single directorate, and the creation of the Global Operations Directorate. The Global Operations Directorate was created to direct field elements in multiple functional areas that had previously been directed from NCIS Headquarters.
In December 2012, the FBI released redacted documents regarding operations against Occupy Wall Street. In one FBI report, the NCIS is quoted as looking into links between Occupy and "organized labor actions" in December 2011.
In January 2013, the Department of the Navy Central Adjudication Facility was consolidated, along with the other Central Adjudications Facilities within the Department of Defense, into a single organization, known as the DoD CAF, per the direction of the Deputy Secretary of Defense. The DoD CAF is currently the sole authority to determine security clearance eligibility of non-Intelligence Agency DoD personnel occupying sensitive positions and/or requiring access to classified material including Sensitive Compartmented Information.
On October 7, 2013, Andrew L. Traver became the fifth civilian Director of NCIS, having been appointed to the position by Secretary of the Navy Ray Mabus. Traver leads an agency that is composed of some 2,500 civilian and military personnel and has a presence in over 150 locations worldwide. He is responsible for executing an annual operating budget of approximately $460 million.
In 2014, in the aftermath of the Washington Navy Yard shooting, NCIS formed the Regional Enforcement Action Capabilities Training team. REACT teams are designed to support investigations and "high-risk" enforcement operations within the United States, including high-risk operations that involve the service of arrest and search warrants, undercover agent and source protection/rescue, undercover operations, high-risk surveillance, and high-risk protective assignments.
On June 4, 2019, Omar R. Lopez became the sixth civilian Director of NCIS, having been appointed to the position by the Secretary of the Navy, Richard V. Spencer. Director Lopez is responsible for approximately 2,000 personnel, including 1,000 federal special agents, in 191 locations around the world.
In late 2019, NCIS went through additional organizational changes. In October, the Central Field Office was reactivated. As its name suggests, the Central Field Office is responsible for investigations and operations in the Central United States. In December, the position of Deputy Director was redesignated as the Deputy Director of Operations and the Principal Executive Assistant Director was redesignated as the Deputy Director of Operational Support.

An Assistant Director is also assigned to some operational and support directorates to serve as the Chief Operations Officer, responsible for the day-to-day oversight and management of the directorate.
The directorates and field offices of NCIS are:

Headquarters

The Russell-Knox Building, named after U.S. Marine Corps Major General John Henry Russell, Jr. and U.S. Navy Commodore Dudley Wright Knox, was built based on the findings of the 2005 Base Realignment and Closure Commission. The commission authorized the project to build the RKB as there was a need to co-locate the headquarters of the different criminal investigative agencies of the U.S. military.
Before the NCIS headquarters was moved to the Russell-Knox Building in 2011, it was located aboard the Washington Navy Yard in Washington, D.C.
Office of the Director
The Office of the Director serves as the central administrative arm of the Director. The office encompasses the Director, the Deputy Directors, and the Director's Staff. The office is headed by the Chief of Staff who is accountable to the Director, via the daily supervision of the Deputy Director of Operational Support, for the effective operation and administration of the Office of the Director.
Other components reporting directly to the Director and/or Deputy Directors are:
The Behavioral Science Group supports the NCIS headquarters and field offices on a worldwide basis by deploying licensed psychologists with specialized training and experience in law enforcement psychology and national security. They are responsible for providing consultations to operations, investigations, and related projects and matters.
The BSG consultations provide insight into relevant behavior; optimizing criminal, counterintelligence, and counter-terrorism investigations and operations; and complementing other resources such as analytical and technical expertise.
Office of Military Support
The Office of Military Support is composed of active duty and reserve US Navy officers and enlisted personnel. They perform in a variety of mission support areas in NCIS offices throughout the world, including protective service operations, supply and logistics, communications, administrative duties, intelligence, and security.

Operational directorates

The operational directorates of NCIS are supervised by the Deputy Director of Operations who is the Chief Operations Officer of NCIS, responsible for criminal investigations, counterintelligence, counterterrorism, tri-service operations, biometrics, technical surveillance countermeasures, behavioral science, technical services, Regional Enforcement Action Capabilities Training, polygraph services, and forensics.
The NCIS currently has two types of operational directorates: functional and field.
The functional directorates are the National Security Directorate and the Criminal Operations Directorate. These directorates are responsible for outlining the goals and objectives of NCIS relating to their functional area through the Program Direction Document. The Executive Assistant Directors exercise direction and supervision of their Program Direction Document through the three field directorates. The EAD's also advise the Deputy Director of Operations on the three field directorate Executive Assistant Directors' performance in meeting the outlined goals and objectives.
The field directorates are the Atlantic Operations Directorate, Pacific Operations Directorate, and the Global Operations Directorate.
The geographic Atlantic Operations and Pacific Operations directorates are divided into field offices, each headed by a Special Agent in Charge, while the functional Global Operations Directorate is divided into field offices and field operational support elements, headed by Special Agents in Charge or Division Chiefs. The SAC / Division Chief is responsible for all operational, investigative, and administrative activities within their geographical/functional area of responsibility. They exercise leadership of geographic implementation of NCIS' goals and objectives through the direction and supervision of Assistant Special Agents in Charge and Supervisory Special Agents. In field offices with only one ASAC, the ASAC is the Chief Operations Officer of the field office, responsible for the day-to-day oversight and management of its activities. In field offices with multiple ASAC's, the ASAC's serve as the heads of specific functions within the field office. The field office headquarters also has specialized teams, headed by Supervisory Special Agents, ready to support the field office's subordinate units by dispatching experienced Special Agents and/or civilian investigators to assist in investigations if a prolonged investigation is required or the investigative resources required exceeds the subordinate unit's capabilities. Usually the senior-most Special Agent of the field team is designated as the Senior Field Agent who may also have some operational and/or administrative responsibilities.
The geographic field offices are divided into NCIS Resident Agencies and NCIS Resident Units. NCISRA's are headed by Supervisory Special Agents who supervise all sworn Special Agents and civilian personnel assigned to the NCISRA. Depending on the size or location of the NCISRA, the Resident Agent in Charge may also supervise other Supervisory Special Agents who serve as team leaders, responsible for a specific investigative/operational function within the NCISRA. Some NCISRA's are further divided into NCISRU's, which are small units consisting of only one or two Special Agents who report directly to the Resident Agent in Charge of the "parent NCISRA." In NCISRU's which are staffed by multiple Special Agents, the senior-most Special Agent is designated as the Senior Resident Agent and may also have some operational and/or administrative responsibilities. NCIS Special Agent Afloat duty posts are also classified as NCISRU's. NCISRU's afloat are under the functional supervision of the field office responsible for the vessel's homeport but receive operational support from the field office responsible for the area where the ship is sailing in.

Specialized programs

Special Agents Afloat

The Special Agent Afloat Program of NCIS sends NCIS Special Agents aboard U.S. aircraft carriers and other ships.
The purpose of the program is to provide professional investigative, counterintelligence, and force protection support to deployed Navy and Marine Corps commanders. These special agents are assigned to aircraft carriers and other deployed major combatants. Their environment can best be described as a "floating city." The assignment offers many of the same investigative challenges found by any criminal investigator working in a metropolitan city. A special agent assigned to a carrier must be skilled in general criminal investigations including: crime scene examination, expert interview techniques, and use of proactive law enforcement procedures to stop criminal activity before it occurs. The special agent afloat also provides guidance on foreign counterintelligence matters, including terrorism. It is also the mission of the special agent afloat to offer Navy and Marine Corps leadership advice and operational support on security issues which might threaten the safety of ships, personnel and resources.
The Special Agent Afloat program was initiated in Europe during March 1967. In April 1971, a special agent was assigned to a deployed carrier for a period of six months with the designation of SAA. By 1978, SAA personnel were assigned to each operational aircraft carrier in the U. S. Navy for a one-year assignment. In 1986, a trial began where two Special Agents Afloat were assigned to aircraft carriers in an effort to determine the feasibility and effectiveness of having two agents assigned full-time while deployed, one focusing on law enforcement/criminal investigations and one on foreign counterintelligence. The trial was discontinued when no longer considered viable.

Protective Operations

The Naval Criminal Investigative Service is the only entity within the Department of the Navy authorized to conduct protection of Department of Defense/Department of the Navy High Risk Billets. The mission of the NCIS Protective Operations Field Office is to prevent terrorist and/or criminal attacks on principals under NCIS executive protection coverage and execute the necessary and appropriate response to a threat and/or attack on a principal. POFO will also initiate investigations on individuals and groups who meet a specific threshold when a threat is detected or needs to be validated.
NCIS provides and manages full-time protection details on key Department of the Navy personnel, including:
To supplement POFO's operational mission, it maintains an internal Protective Intelligence Unit to identify potential threats that could affect a principal, understand a principal's level of vulnerability to any given threat, and use available intelligence to mitigate threats and/or risk to a principal. The Protective Intelligence Unit works extensively with the U.S. Secret Service, Pentagon Force Protection Agency, U.S. Army Criminal Investigation Command, U.S. Air Force Office of Special Investigations, and the U.S. Marshals Service.

Multiple Threat Alert Center

The Multiple Threat Alert Center utilizes NCIS' worldwide presence and combination of law enforcement, counterintelligence, intelligence and security capabilities to identify a wide range of threats to Navy and Marine Corps personnel and assets around the world. The MTAC is a unique platform in that it merges intelligence from other agencies with information from NCIS source networks and law enforcement activities worldwide to provide the most relevant operational support to Navy and Marine Corps commanders.

Regional Enforcement Action Capabilities Training Team

In 2014, in the aftermath of the Washington Navy Yard shooting, NCIS formed the Regional Enforcement Action Capabilities Training team. REACT teams are designed to support investigations and "high-risk" enforcement operations within the United States, including high-risk operations that involve the service of arrest and search warrants, undercover agent and source protection/rescue, undercover operations, high-risk surveillance, and high-risk protective assignments.
REACT team is organized, equipped, directed, and controlled by the Deputy Assistant Director, Criminal Investigations and Operations Department, Criminal Operations Directorate, and is under the direction of the REACT commander and deputy commander. Because of NCIS' changing needs and mobility, realignments of field offices, and geographical differences, the composition of each team may vary. In general, each REACT team will be composed of one team leader, one assistant team leader, and multiple tactical operators. Assignment to REACT is strictly voluntary and REACT is classified as a collateral duty, meaning Special Agents assigned to REACT remain in their original assignments within the field office when not called into service with REACT.
If REACT assistance is determined to be necessary, the field office SAC or his/her designee will contact the REACT commander, or deputy commander if the commander is unavailable, for further discussion and evaluation. The Deputy Assistant Director of Criminal Investigations and Operations maintains final approval authority for the use of REACT and the execution of a proposed operation.

Armaments

As of 2019, the current standard issue pistols of NCIS Academy graduates are the SIG Sauer P229R and the SIG Sauer P239 in.40 S&W. Previously, both pistols were equipped with the SIG Sauer DAK trigger system. Pistols with the DAK trigger remain in use. The previous standard issue pistol was the SIG Sauer M11 in 9×19mm. Agents may also qualify with a weapon from an approved list of manufacturers in.38 Special, 9×19mm,.40 S&W, or.45 ACP.
Field Offices are issued a number of Mossberg 500 or Remington 870 shotguns in 12 Gauge and the M4 platform for use when appropriate.
For combat environments, special agents are issued the U.S. Navy MK18.
