Information:  - Operation Banner was the operational name for the British Armed Forces ' operation in Northern Ireland from August 1969 to July 2007 . It was initially deployed at the request of the unionist government of Northern Ireland to support the Royal Ulster Constabulary ( RUC ) . After the 1998 Belfast Agreement , the operation was gradually scaled down . Its role was to assert the authority of the government of the United Kingdom in Northern Ireland . The main opposition to the British military 's deployment came from the Provisional Irish Republican Army ( IRA ) . It waged a guerrilla campaign against the British military from 1970 - 97 . An internal British Army document released in 2007 stated that , whilst it had failed to defeat the IRA , it had made it impossible for the IRA to win through violence , and reduced substantially the death toll in the last years of conflict .  - The War Office was a department of the British Government responsible for the administration of the British Army between the 17th century and 1964, when its functions were transferred to the Ministry of Defence.  - The Royal Ulster Constabulary was the police force in Northern Ireland from 1922 to 2001. Following the awarding of the George Cross in 2000, its formal title became the Royal Ulster Constabulary, GC. It was founded on 1 June 1922 out of the Royal Irish Constabulary (RIC). At its peak the force had around 8,500 officers with a further 4,500 who were members of the RUC Reserve. During the Troubles, 319 members of the RUC were killed and almost 9,000 injured in paramilitary assassinations or attacks, mostly by the Provisional IRA, which made, by 1983, the RUC the most dangerous police force in the world in which to serve. In the same period, the RUC killed 55 people, 28 of whom were civilians.  - The British Army is the principal land warfare force of the United Kingdom. The force was initially administered by the War Office from London, which in 1964 was subsumed into the Ministry of Defence. The professional head of the British Army is the Chief of the General Staff.  - Ulster (or "Cúige Uladh" , Ulster Scots: "Ulstèr" or "Ulster") is a province in the north of the island of Ireland. In ancient Ireland, it was one of the fifths ruled by a "rí ruirech", or "king of over-kings".  - Ireland, also described as the Republic of Ireland ('), is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the ', consists of a lower house, ', an upper house, ', and an elected President (') who serves as the largely ceremonial head of state, but with some important powers and duties.

It is usually short-term help until the long-term help by government and other institutions replaces it. Among the people in need belong homeless, refugees, victims of natural disasters, wars and famines. The primary purpose of humanitarian aid is to save lives, reduce suffering and respect to human dignity. Humanitarian aid is material or logistical assistance provided for humanitarian purposes, typically in response to humanitarian crises including natural disasters and man-made disaster. The primary objective of humanitarian aid is to save lives, alleviate suffering, and maintain human dignity. It may therefore be distinguished from development aid, which seeks to address the underlying socioeconomic factors which may have led to a crisis or emergency.  - The Good Friday Agreement (GFA) or Belfast Agreement (or ; Ulster-Scots: "Guid Friday Greeance" or "Bilfawst Greeance") was a major political development in the Northern Ireland peace process of the 1990s.   - The government of Northern Ireland is, generally speaking, whatever political body exercises political authority over Northern Ireland. A number of separate systems of government exist or have existed in Northern Ireland.   - The Northern Ireland Act 1998 (c.47) is an Act of the Parliament of the United Kingdom which established a devolved legislature for Northern Ireland, the Northern Ireland Assembly, after decades of direct rule from Westminster.  - The Northern Ireland Assembly (Ulster Scots: "Norlin Airlan Assemblie") is the devolved legislature of Northern Ireland. It has power to legislate in a wide range of areas that are not explicitly reserved to the Parliament of the United Kingdom, and to appoint the Northern Ireland Executive. It sits at Parliament Buildings at Stormont in Belfast.  - The George Cross (GC) is the second highest award of the United Kingdom honours system. It is awarded for gallantry "not in the face of the enemy" to members of the British armed forces and to British civilians. It has always been able to be awarded posthumously. It was previously awarded to Commonwealth countries, most of which have established their own honours systems and no longer recommend British honours. It may be awarded to a person of any military rank in any service and to civilians including police, emergency services and merchant seamen although no British civilian has received the award since 1976. Many of the awards have been personally presented by the British monarch to both recipients and in the case of posthumous awards to next of kin. These investitures are usually held at Buckingham Palace.  - Northern Ireland (; Ulster Scots: "") is a top-level constituent unit of the United Kingdom in the northeast of Ireland. It is variously described as a country, province, region, or "part" of the United Kingdom, amongst other terms. Northern Ireland shares a border to the south and west with the Republic of Ireland. In 2011, its population was 1,810,863, constituting about 30% of the island's total population and about 3% of the UK's population. Established by the Northern Ireland Act 1998 as part of the Good Friday Agreement, the Northern Ireland Assembly holds responsibility for a range of devolved policy matters, while other areas are reserved for the British government. Northern Ireland co-operates with the Republic of Ireland in some areas, and the Agreement granted the Republic the ability to "put forward views and proposals" with "determined efforts to resolve disagreements between the two governments".  - A paramilitary is a semi-militarized force whose organizational structure, tactics, training, subculture, and (often) function are similar to those of a professional military, but which is not included as part of a state's formal armed forces.  - The military, also called the armed forces, are forces authorized to use deadly force, and weapons, to support the interests of the state and some or all of its citizens. The task of the military is usually defined as defense of the state and its citizens, and the prosecution of war against another state. The military may also have additional sanctioned and non-sanctioned functions within a society, including, the promotion of a political agenda, protecting corporate economic interests, internal population control, construction, emergency services, social ceremonies, and guarding important areas. The military can also function as a discrete subculture within a larger civil society, through the development of separate infrastructures, which may include housing, schools, utilities, food production and banking.  - The British Armed Forces form the military of the United Kingdom, tasked with defence of the country, its overseas territories, and the Crown dependencies. They also promote the UK's wider interests, support international peacekeeping efforts, and provide humanitarian aid.  - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union.  - The Troubles is the common name for the ethno-nationalist conflict in Northern Ireland during the late 20th century. Also known internationally as the Northern Ireland conflict, it is sometimes described as a "guerrilla war" or "low-level war". The conflict began in the late 1960s and is usually deemed to have ended with the Good Friday "Belfast" Agreement of 1998. Although the Troubles mainly took place in Northern Ireland, violence spilled over at times into parts of the Republic of Ireland, England and mainland Europe.  - A police force is a constituted body of persons empowered by the state to enforce the law, protect property, and limit civil disorder. Their powers include the legitimized use of force. The term is most commonly associated with police services of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are often defined as being separate from military or other organizations involved in the defense of the state against foreign aggressors; however, gendarmerie are military units charged with civil policing.  - The Crown dependencies are three territories of the United Kingdom: the Isle of Man in the Irish Sea, and the Bailiwicks of Jersey and Guernsey in the English Channel. Being independently administered jurisdictions, they do not form part of either the United Kingdom or the British Overseas Territories. They are self-governing possessions of the Crown (defined uniquely in each jurisdiction). Internationally, the dependencies are considered "territories for which the United Kingdom is responsible" rather than as sovereign states. As a result, they are not member states of the Commonwealth of Nations. However, they do have a relationship with the Commonwealth, the European Union, and other international organisations and are members of the BritishIrish Council. They are not part of the European Union (EU), although they are within the EU's customs area.  - Peacekeeping refers to activities intended to create conditions that favor lasting peace. Research generally finds that peacekeeping reduces civilian and battlefield deaths and reduces the risk of renewed warfare.  - The Royal Irish Constabulary (RIC, Irish: "Constáblacht Ríoga na hÉireann"; simply called the Irish Constabulary 183667) was the armed police force of the United Kingdom in Ireland from the early nineteenth century until 1922. A separate civic police force, the unarmed Dublin Metropolitan Police controlled the capital, and the cities of Derry and Belfast, originally with their own police forces, later had special divisions within the RIC. About seventy-five percent of the RIC were Roman Catholic and about twenty-five percent were of various Protestant denominations, the Catholics mainly constables and the Protestants officers. The RIC's successful system of policing influenced the armed Canadian North-West Mounted Police (predecessor of the Royal Canadian Mounted Police), the armed Victoria Police force in Australia, and the armed Royal Newfoundland Constabulary in Newfoundland. In consequence of the Anglo-Irish Treaty, the RIC was disbanded in 1922 and was replaced by the Garda Síochána in the Irish Free State and the Royal Ulster Constabulary in Northern Ireland.
