Colonel Joe Mulligan (Irish Army), current Director of Military Intelligence

The Directorate of Military Intelligence (national security of the Republic of Ireland. The Directorate operates domestic intelligence and foreign intelligence sections, providing intelligence to the Government of Ireland concerning threats to the security of the state and the national interest from internal and external sources.[2] Military Intelligence falls under the structure of the Irish Army, but is the intelligence section of all Defence Forces branches. The Directorate of Military Intelligence draws staff from the Army, Naval Service and Air Corps. The Irish military special operations forces, the Army Ranger Wing (ARW), carries out physical tasks in support of Military Intelligence in Ireland and overseas, and the Communications and Information Services Corps (CIS) provides technical and electronic support. The agency is commonly referred to as "G2", and works closely with the Garda Síochána Special Detective Unit (SDU), the national police counter-terrorism and counter-espionage unit.[3]

Mission and organisation

The duties of the Defence Forces Directorate of Military Intelligence[4] are;

  • The provision of security and intelligence in relation to the state and its national interests, both domestic and foreign, and;
  • To provide operational intelligence and security to deployed Irish forces globally.

The Directorate of Military Intelligence staffs members drawn from the entire Defence Forces (Army, Naval Service and Air Corps), who then serve on a full-time basis with the organisation. Military Intelligence personnel regularly train, liaise and deploy with foreign intelligence, government and non-government agencies to share knowledge and best practice. This ensures they keep abreast of threats and are able to collate essential intelligence to further protect the state, the Defence Forces and its interests. The service is under the command of a Colonel, known as the Director of Military Intelligence,[5] who provides regular intelligence briefings to the Deputy Chief of Staff (Operations), Chief of Staff of the Defence Forces and the Secretary General of the Department of Defence. The Director provides a monthly intelligence briefing in-person to the Minster for Defence. The Chief of Staff briefs the government cabinet on matters of state security, as well as the secretive National Security Committee (NSC).[6]

Although the organisation's number of employees and budget are classified, it is estimated permanent personnel in the unit number in the hundred(s), with a further 150/200 operatives in the Army Ranger Wing (ARW), who conduct missions at the behest of Military Intelligence. The funding comes from the overall Department of Defence budget (€1.16 billion in 2012).[7] The only publicly known funding is that for the budget to pay confidential informants, through the "Secret Service" budget, which is shared with the Garda Crime & Security Branch (CSB). In 2014, this figure was €1 million.[8] Operatives from the Directorate of Military Intelligence carry firearms on operations both at home and abroad, and those in the Directorate regularly do not wear uniform. The Garda Special Detective Unit (SDU) works closely with the unit on domestic matters. Military Intelligence operates out of a number of locations in Dublin and County Kildare, and their headquarters are understood to be based at McKee Barracks, Dublin and the Department of Defence Headquarters in Newbridge, County Kildare. The latter is rumoured to house sophisticated modern technology for espionage, the building was completed in 2010 after a number of years of construction, at a cost of €30 million.[9]


National Security Intelligence Section

The Directorate of Military Intelligence National Security Intelligence Section (NSIS) deals with threats to the Irish state and Defence Forces in general. This includes identifying, monitoring and assessing possible threats to the state and Irish national interests at home and abroad, be it by hostile intelligence services, terrorist groups and/or criminal organisations. Counter-intelligence forms a large part of the section's remit, in addition to fulfilling counter-terrorist, counter-subversion, counter-insurgency, counter-sabotage roles, and physical security of critical infrastructure. The National Security Intelligence Section works very closely with the Garda SDU and Garda National Surveillance Unit (NSU) to spy on potential terrorism threats, particularly from Islamic terrorists and dissident republicans.[10] NSIS members can conduct interrogations of suspects alongside Gardaí.[11]

Defence Intelligence Section

The Directorate of Military Intelligence Defence Intelligence Section is staffed by military commissioned and non-commissioned officers. It is tasked with providing intelligence support to the Defence Forces. Staff actively monitor relevant political, economic, social and military situations globally to produce intelligence reports and strategic studies to support operations. The agents in this section can be found briefing all the way up to the Minister for Defence. The Directorate is responsible for conducting background checks of all Defence Forces personnel through close cooperation with the Garda Central Vetting Unit (GCVU).[12] The Defence Intelligence Section is tasked with keeping members of the Defence Forces safe, be it in Ireland or abroad during active military engagements. The Army Ranger Wing Intelligence Section deploys in foreign countries alongside Military Intelligence soldiers during Irish military deployments, which are generally peacekeeping missions on behalf of the United Nations, European Union and NATO (Partnership for Peace), due to Ireland's policy of military neutrality.[13]


Founded in the mid-1920s following the Anglo-Irish Treaty, the Office of the Directorate of Intelligence was originally the intelligence arm of the Irish Army, hence its code-name "G2" or "J2", which is a term used in western armed forces to refer to their Intelligence and Security branch. Later the Directorate became the intelligence service for the entire Irish armed forces, the Defence Forces (Army, Naval Service and Air Corps) and took on more national security roles. G2 spent much of its early efforts combating the Anti-Treaty IRA, in the Republic of Ireland, and also operated in Northern Ireland.[14]

G2 first came to public attention during World War II, known in Ireland as The Emergency. Although Ireland had a policy of military neutrality and was "non-belligerent" during WWII, G2 formed secret agreements with the United Kingdom's Military Intelligence Section 5 (MI5) and the United States' Office of Strategic Services (OSS), the predecessor to the Central Intelligence Agency (CIA). During this period, G2 intercepted German naval and aerial communications through listening stations located across Ireland, sharing the information with Allied forces.[15] Under the legendary Colonel Daniel "Dan" Bryan, Director of Intelligence, G2 apprehended all thirteen Nazi spies sent to Ireland and broke German codes during the war, under the guise of cryptologist Richard J. Hayes.

Individuals can apply to be selected for the Directorate of Military Intelligence, and they must be Officers or NCOs to be considered for appointment. Unlike a number of similar military forces, the Irish Defence Forces actively include intelligence as part of Officer and NCO education,[27] but those selected to join the Directorate receive further specialist training. The Defence Forces run their own Defence Intelligence & Security course. The course runs for a number of months and covers the main areas of intelligence operations, including the principles of intelligence operations, defence intelligence, intelligence analysis, and combat intelligence. The course is supported by additional "on-the-job" training as part of the Directorate. This includes additional weapons, surveillance and communications training to support ongoing operations. Further training in languages is available, and specialist training on sensitive subjects such as religion, culture, ethnicity and radicalisation are also provided. Members of the Directorate may also receive further training with friendly forces overseas.[28]

Training and selection

Ireland is not believed to engage in mass surveillance[25] - as has been alleged in other western countries - however, it is reported to be a member of the ECHELON SIGINT (signals intelligence) network, sharing and receiving information with its members (Australia, Canada, New Zealand, United Kingdom and United States). The Defence Forces CIS Corps is jointly responsible with the Military Intelligence Directorate for SIGINT and cyber operations within the Defence Forces. According to the Department of Defence: "The Defence Forces adheres to the provisions of all legislation regulating the conduct of intelligence gathering. The Interception of Postal Packets and Telecommunications Messages (Regulation) Act 1993 does provide the Defence Forces with the authority to conduct intelligence led operations involving surveillance, electronic communications and stored electronic information in order to safeguard and maintain the security of the State. The Criminal Justice (Surveillance) Act 2009 also provides for surveillance to be conducted by the Defence Forces in order to safeguard the security of the State."[26]

Electronic surveillance

It has been alleged that Ireland facilitated the CIA's extraordinary rendition program of terrorism suspects in the aftermath of 9/11, including the secret detention and interrogation of suspects. It is claimed that Irish airports Casement Aerodrome (military) and Shannon International Airport (civilian)—used by the US military as stopover hubs—have been used by the CIA for rendition operations, with support from the Irish government.[24]

Following the September 11 attacks on the United States in 2001, the Directorate of Military Intelligence significantly expanded their operations both internally and externally to provide the Irish government with a better intelligence picture in relation to terror threats emanating from al-Qaeda and affiliated groups, working with western partners. The 2004 Madrid train bombings (11-M) in Spain and 7 July 2005 London bombings in the United Kingdom also saw an increase in the budget and deployments of Irish intelligence agents. From 2006 to 2014, it has been reported that Military Intelligence and ARW Intelligence Section operatives were on the ground in; Afghanistan, Iraq, Syria, Lebanon, Israel, Sudan, Ivory Coast, Liberia, Kosovo and Bosnia-Herzegovina as part of various international missions.[21] The Directorate receives intelligence reports from civil servants posted at Irish diplomatic missions overseas, via the Department of Foreign Affairs and Trade. Irish Military Intelligence works closely with the British Security Service (MI5) and Secret Intelligence Service (SIS/MI6), American Central Intelligence Agency (CIA) and National Security Agency (NSA), and is understood to have a relationship with Israeli Mossad.[22][23]
