Barrack buster is the colloquial name given to several improvised mortars, developed in the 1990s by the engineering unit of the Provisional Irish Republican Army (IRA).
The improvised mortar properly called "barrack buster" - known to the British security forces as the Mark 15 mortar - fired a 1 metre (3 ft 3 in) long metal propane cylinder with a diameter of 36 centimetres (14 in), which contained around 75 kg (165 lb) of home-made explosives and had a range of 75 to 275 metres (246 to 902 ft). The cylinder is an adaptation of a commercial gas cylinder produced by the Cobh company Kosangas for heating and cooking, and used in rural areas across Ireland. [1]
The Mark 15 was first used in an attack on 7 December 1992 against an RUC/British Army base in Ballygawley, County Tyrone, [1] [2] The projectile, fired from a tractor parked near the town's health center, was deflected by the branches of a tree besides the perimeter fence. A number of civilians had to be evacuated. [3] [4] It took ten hours for the British Army technicians to defuse the device. [5] A later IRA statement acknowledged that the mortar bomb had "failed to detonate properly". [6] The following, more successful attack took place on 20 January 1993 in Clogher, also in County Tyrone, [2] where the local RUC compound was heavily damaged, [7] and several RUC constables wounded. [8]
The barrack buster belongs to a series of home-made mortars developed since the 1970s. The first such mortar—Mark 1—was used in an attack in May 1972 and it was soon followed by the first of a series of improved or differentiated versions stretching into the 1990s:
The intensification of the IRA's mortar campaign in the late 1980s led the British government to increase the number of army troops in Northern Ireland from its lowest ebb of 9,000 in 1985 to 10,500 in 1992. [28] Also in the 1980s, defense authorities undertook a huge and costly plan to fortify its security facilities across the region to tackle the threat. [29] The IRA's use of mortars combined with heavy machine guns compelled the British Army to build their main checkpoints more than a mile away from the Irish border by 1992. [30]
These mortars were also used against targets in England, such as the Downing Street attack on 7 February 1991, and the Heathrow mortar attacks in March 1994. Both attacks were intended by the IRA to put pressure on the British Government to negotiate with them. [31] [32]
In 1972 the Official IRA developed a type of mortar which was used in attacks against several British Army installations on 5 December that year. [33] Provisional IRA-type mortars have been used by the Real IRA, who also developed their own fuzing system, in the 2000s. [34] In early 2000 a new type of mortar was tested by the Real IRA in County Fermanagh. The weapon was classified as a "Mark-19" by the British Army. [35] Furthermore, what appears to be a similar or identical mortar technology known in Colombia as "cilindros" (or "cylinders" in English) have been used since 1998 by the Revolutionary Armed Forces of Colombia (FARC). ETA in Spain was in 2001 rumoured to have built mortars "very similar" to the IRA's. [36] The possible transfer of this mortar technology to the FARC was a central issue in the arrest in August 2001 and later trial of the so-called Colombia Three group of IRA members, who were found innocent of false claims by Colombian authorities and the United States House Committee on Foreign Affairs that they “allegedly” trained FARC in the manufacture and use of this mortar technology even though there was no evidence presented at trial to prove the claim. [37] [38]
A derived term in Belfast refers to a two or three-litre bottle of inexpensive white cider. [39]
The Real Irish Republican Army, or Real IRA (RIRA), was a dissident Irish republican paramilitary group that aimed to bring about a United Ireland. It was formed in 1997 following a split in the Provisional IRA by dissident members, who rejected the IRA's ceasefire that year. Like the Provisional IRA before it, the Real IRA saw itself as the only rightful successor to the original Irish Republican Army and styled itself as simply "the Irish Republican Army" in English or Óglaigh na hÉireann in Irish. It was an illegal organisation in the Republic of Ireland and designated a proscribed terrorist organisation in the United Kingdom and the United States.
The East Tyrone Brigade of the Provisional Irish Republican Army (IRA), also known as the Tyrone/Monaghan Brigade was one of the most active republican paramilitary groups in Northern Ireland during "the Troubles". It is believed to have drawn its membership from across the eastern side of County Tyrone as well as north County Monaghan and south County Londonderry.
From 1969 until 1997, the Provisional Irish Republican Army (IRA) conducted an armed paramilitary campaign primarily in Northern Ireland and England, aimed at ending British rule in Northern Ireland in order to create a united Ireland.
The proxy bomb, also known as a human bomb, is a tactic that was used mainly by the Provisional Irish Republican Army (IRA) in Northern Ireland during the conflict known as "the Troubles". It involved forcing people to drive car bombs to British military targets after placing them or their families under some kind of threat The tactic has also being replicated by Ulster Loyalist militants and was later adopted by the FARC in Colombia and by rebels in the Syrian Civil War.
This is a chronology of activities by the Continuity Irish Republican Army (CIRA), an Irish republican paramilitary group. The group started operations in 1994, after the Provisional Irish Republican Army began a ceasefire.
On 13 December 1989 the Provisional Irish Republican Army (IRA) attacked a British Army permanent vehicle checkpoint complex manned by the King's Own Scottish Borderers (KOSB) near the Northern Ireland–Republic of Ireland border at Derryard townland, a few miles north of Rosslea, County Fermanagh. The IRA unit, firing from the back of an armoured dump truck, attacked the small base with heavy machine-guns, grenades, anti-tank rockets and a flamethrower. A nearby Army patrol arrived at the scene and a fierce firefight erupted. The IRA withdrew after leaving a van bomb inside the complex, but the device did not fully detonate. The assault on the outpost left two soldiers dead and two wounded.
On 7 December 1985 the Provisional Irish Republican Army (IRA) attacked the Royal Ulster Constabulary (RUC) base at Ballygawley, County Tyrone. Two RUC officers were shot dead and the base was raked with gunfire before being destroyed by a bomb, which wounded a further three officers.
This is a timeline of actions by the Irish republican paramilitary groups referred to as the Real Irish Republican Army and New Irish Republican Army. The Real IRA was formed in 1997 by disaffected members of the Provisional IRA. Since July 2012, when Republican Action Against Drugs (RAAD) and other small republican groups merged with it, the group has been called the New IRA; although it continues to call itself simply "the Irish Republican Army".
This is a chronology of activities by the Provisional Irish Republican Army (IRA) from 1980 to 1989. For actions before and after this period see Chronology of Provisional Irish Republican Army actions.

The Osnabrück mortar attack was an improvised mortar attack carried out by a Provisional Irish Republican Army (IRA) unit based in mainland Europe on 28 June 1996 against the British Army's Quebec Barracks at Osnabrück Garrison near Osnabrück, Germany.
On 19 March 1994, a British Army Lynx helicopter was shot down by the Provisional Irish Republican Army (IRA) in Northern Ireland. A unit of the IRA's South Armagh Brigade fired a heavy improvised mortar at the British Army base in Crossmaglen, County Armagh. The mortar round hit and shot down the helicopter, serial number ZD275, while it was hovering over the helipad. Three British soldiers and a Royal Ulster Constabulary (RUC) member were wounded.
The Mullacreevie ambush took place on 1 March 1991, when a mobile patrol of the Ulster Defence Regiment composed of two Land Rover vehicles was attacked with an improvised horizontal mortar by a Provisional IRA active service unit from the North Armagh Brigade while passing near Mullacreevie housing estate, on the west side of Armagh City. One member of the UDR was killed instantly when the leading Land Rover was hit, while another died of wounds two days later. Two other soldiers were maimed for life.
On 11 August 1986, the East Tyrone Brigade of the Provisional Irish Republican Army (IRA) attacked the Royal Ulster Constabulary (RUC) base at The Birches near Portadown, County Armagh, Northern Ireland. The unmanned base was raked with gunfire before being destroyed by a 200 pounds (91 kg) bomb, which was driven through the gate of the base in the bucket of a JCB digger.
In the Altnaveigh landmine attack of 19 May 1981, five British soldiers were killed and their armoured vehicle destroyed by a Provisional IRA landmine at Altnaveigh, a rural area outside Newry in County Armagh, Northern Ireland. The landmine was detonated remotely when the vehicle passed over it. The attack happened during a period of heightened tension over the 1981 Irish hunger strike.
Throughout the protracted conflict in Northern Ireland (1960s-1998), the Provisional IRA developed a series of improvised mortars to attack British Army and Royal Ulster Constabulary (RUC) security bases. The organisation also purchased both light and heavy machine guns in order to hamper the British Army supply of border bases by helicopter. The IRA fitted vehicles, specially vans and trucks, with both types of weapons. Vans, trucks and tractors were modified to transport concealed improvised mortars to a launch area near the intended target and fire them, while light and heavy trucks were employed as firing platforms mounting machine guns, particularly M60s and DShKs. Improvised armoured vehicles and heavy equipment were also used to penetrate the perimeter of fortified security bases. The IRA vehicles were often disguised as belonging to civilian companies or even government agencies.
On 12 December 1993, a unit of the Provisional Irish Republican Army's (IRA) East Tyrone Brigade ambushed a two-men unmarked mobile patrol of the RUC in Fivemiletown, County Tyrone. Two constables were shot and killed instantly. A military helicopter was also fired at by a second IRA unit in the aftermath of the incident, during a follow-up operation launched in the surroundings of the town by both the British Army and the RUC. A number of suspects were questioned, but the perpetrators made good their escape. The action occurred just three days before the Downing Street Declaration.
