The Red Hand Commando (RHC) is a small secretive Ulster loyalist paramilitary group in Northern Ireland, which is closely linked to the Ulster Volunteer Force (UVF).
 Its aim was to combat Irish republicanism – particularly the Irish Republican Army (IRA) – and to maintain Northern Ireland's status as part of the United Kingdom.
 The Red Hand Commando has killed 13 people during The Troubles, 12 civilians and one of its own members.
 It is named after the Red Hand of Ulster.
John Oliver Weir (born 1950) is an Ulster loyalist born in the Republic of Ireland.
 He served as an officer in Northern Ireland's Royal Ulster Constabulary's (RUC) Special Patrol Group (SPG) (a tactical reserve unit), and was a volunteer in the illegal Ulster Volunteer Force (UVF).
 As a member of the UVF's Mid-Ulster Brigade led by Robin "the Jackal" Jackson, Weir was a part of the Glenanne gang, a group of loyalist extremists that carried out sectarian attacks mainly in the County Armagh area in the mid-1970s.
 Along with his RUC colleague Billy McCaughey, Weir was convicted of the 1977 sectarian killing of Catholic chemist William Strathern and sentenced to life imprisonment.
 Weir's affidavit which implicated Jackson, other members of the Glenanne gang, soldiers of the Ulster Defence Regiment (UDR), and his colleagues in the RUC and SPG, in a series of sectarian attacks, including the Dublin and Monaghan bombings, was published in the 2003 Barron Report, the findings of an official investigation into the 1974 car bombings commissioned by Irish Supreme Court Justice Henry Barron.
During the Troubles in Northern Ireland, a total of 14 people were killed in Troubles-related violence in or near the village of Maghera, County Londonderry.
 Of the 13 from Northern Ireland, 11 were Protestant and two were Catholic.
 Seven of the Protestant victims were members of the security forces (six Ulster Defence Regiment (UDR), two Royal Ulster Constabulary (RUC), one British Army) and another was the ten-year-old daughter of a UDR man, killed along with her father by a bomb planted in his car.
 Another victim was shot after being mistaken for his co-worker, an UDR member.
 Only three of the security force victims were killed while on-duty.
 Both the RUC men were killed by the Irish National Liberation Army; all the other Protestant victims were killed by the Provisional Irish Republican Army.
 Both the Catholic victims were killed by loyalist paramilitaries, one by the Ulster Volunteer Force and one by the Loyalist Volunteer Force.
 One was a Sinn Féin councillor.
The Loyalist Volunteer Force (LVF) is a small Ulster loyalist paramilitary group in Northern Ireland.
 It was formed by Billy Wright in 1996 when he and his unit split from the Ulster Volunteer Force (UVF) after breaking its ceasefire.
 They had belonged to the UVF's Mid-Ulster Brigade and Wright had been the brigade's commander.
 In a two-year period from August 1996, the LVF waged a paramilitary campaign with the stated goal of combatting Irish republicanism.
 During this time it killed at least 14 people in gun and bomb attacks.
 Almost all of its victims were Catholic civilians who were killed at random.
 The LVF called off its campaign in August 1998 and decommissioned some of its weapons, but in the early 2000s a loyalist feud led to a number of killings.
 Since then, the LVF has been largely inactive, but its members are believed to have been involved in rioting and organized crime.
 In 2015, the security forces stated that the LVF "exists only as a criminal group" in Mid-Ulster and Antrim.
The Glenanne gang or Glenanne group was a secret informal alliance of Ulster loyalists, mostly from Northern Ireland, who carried out shooting and bombing attacks against Catholics and nationalists during the Troubles, beginning in the 1970s.
 Most of its attacks took place in the "murder triangle" area of counties Armagh and Tyrone.
 It also launched some attacks elsewhere in Northern Ireland and in the Republic of Ireland.
 The gang included British soldiers from the Ulster Defence Regiment (UDR), police officers from the Royal Ulster Constabulary (RUC), and members of the Mid-Ulster Brigade of the Ulster Volunteer Force (UVF).
 Twenty-five British soldiers and police officers were named as purported members of the gang.
 Details about the group have come from many sources, including the affidavit of former member and RUC officer John Weir; statements by other former members; police, army and court documents; and ballistics evidence linking the same weapons to various attacks.
 Since 2003, the group's activities have also been investigated by the 2006 "Cassel Report", and three reports commissioned by Irish Supreme Court Justice Henry Barron, known as the "Barron Reports".
 A book focusing on the group's activities, "Lethal Allies: British Collusion in Ireland", was published in 2013.
 It drew on all the aforementioned sources, as well as Historical Enquiries Team investigations.
The Ulster Volunteer Force (UVF) is an Ulster loyalist paramilitary group in Northern Ireland.
 It emerged in 1966 and is named after the original UVF of the early 20th century.
 Its first leader was Gusty Spence, a former British soldier.
 The group undertook an armed campaign of almost thirty years during the Troubles.
 It declared a ceasefire in 1994 and officially ended its campaign in 2007, although some of its members have continued to engage in violence and criminal activities.
 The group is classified as a terrorist organisation by the United Kingdom, Republic of Ireland and United States.
The Tandragee killings took place in the early hours of Saturday 19 February 2000 on an isolated country road outside Tandragee, County Armagh, Northern Ireland.
 Two young Protestant men, Andrew Robb and David McIlwaine, were beaten and repeatedly stabbed to death in what was part of a Loyalist feud between the loyalist Ulster Volunteer Force (UVF) and their rivals, the breakaway Loyalist Volunteer Force (LVF).
 The men were not members of any loyalist paramilitary organisation.
 It later emerged in court hearings that Robb had made disparaging remarks about the killing of UVF Mid-Ulster Brigade leader Richard Jameson by an LVF gunman the previous month.
 This had angered the killers, themselves members of the Mid-Ulster UVF, and in retaliation they had lured the two men to the remote lane on the outskirts of town, where they killed and mutilated them.
The 2011 Northern Ireland riots were a series of riots between 20 June 2011 and 16 July 2011, starting originally in Belfast, before spreading to other parts of Northern Ireland.
 They were initiated by the Ulster Volunteer Force.
Clifford Peeples (sometimes spelled Clifford Peoples) (born c.1970) is a self-styled pastor in Northern Ireland who has been associated with Ulster loyalist activity.
 Peeples has been a member of the Ulster Volunteer Force (UVF), the Loyalist Volunteer Force (LVF) prisoners' spokesman and leader of the Orange Volunteers.
A loyalist feud refers to any of the sporadic feuds which have erupted almost routinely between Northern Ireland's various loyalist paramilitary groups during and after the ethno-political conflict known as the Troubles broke out in the late 1960s.
 The feuds have frequently involved problems between and within the Ulster Defence Association (UDA) and the Ulster Volunteer Force (UVF) as well as, later, the Loyalist Volunteer Force (LVF).
