The Defence Forces (Fórsaí Cosanta, officially styled Óglaigh na hÉireann) are the armed forces of Ireland. They encompass the Army, Air Corps, Naval Service, and Reserve Defence Forces.
The Supreme Commander of the Defence Forces is the President of Ireland. All Defence Forces officers hold their commission from the President, but in practice the Minister for Defence acts on the President's behalf and reports to the Government of Ireland. The Minister for Defence is advised by the Council of Defence on the business of the Department of Defence.
As of February 2023, there were 7,987 permanent personnel in the Defence Forces, a decrease from September 2020 when there were 8,529 personnel, comprising 6,878 Army, 752 Air Corps and 899 Naval Service personnel.
The Irish state has a long-standing policy of non-belligerence in armed conflicts, including neutrality in World War II. Ireland's military capabilities are modest. However, the state has a long history of involvement in United Nations peacekeeping operations. Functions of the Defence Forces include:
Preparation for the defence of the state against armed attack.
Assisting the police force, the Garda Síochána, including the protection of the internal security of the state.
Peacekeeping, crisis management and humanitarian relief operations in support of the United Nations.
Policing the fisheries, in accordance with the state's obligations under European Union agreements.
Miscellaneous civil contingency duties requested by the government such as search and rescue, air ambulance provision, providing secure air transport for ministers, assistance in the event of natural and other disasters, ensuring the maintenance of essential services, and assisting in dealing with oil pollution at sea.
History of the Irish Army
The Defence Forces trace their origins to the Irish Volunteers, founded in 1913. Their official Irish-language title, Óglaigh na hÉireann, is taken from the equivalent Irish-language title of the Irish Volunteers, as are their cap badge and the buttons worn on ceremonial uniforms (the buttons are still marked with the initials "IV").
