United Kingdom

The United Kingdom of Great Britain and Northern Ireland (commonly known as the United Kingdom, the UK, or Britain) is a sovereign state located off the northwestern coast of continental Europe. It is an island country, spanning an archipelago including Great Britain, the northeastern part of Ireland, and many small islands. Northern Ireland is the only part of the UK with a land border, sharing it with the Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, the North Sea, the English Channel and the Irish Sea. The largest island, Great Britain, is linked to France by the Channel Tunnel.

The United Kingdom has appeared in all Call of Duty games so far, with the exception of the Playstation 2 and Nintendo DS releases of World at War.

World War II (1939-1945)
The United Kingdom, along with the British Empire's crown colonies, especially British India, declared war on Nazi Germany in 1939, after the German invasion of Poland. Hostilities with Japan began in 1941, after it attacked British colonies in Asia. The Axis powers were defeated by the Allies in 1945.

The end of World War II saw a landslide General Election victory for Clement Attlee and the Labour Party. They were elected on a manifesto of greater social justice with left wing policies such as the creation of a National Health Service, an expansion of the provision of council housing and nationalisation of the major industries. The UK at the time was poor, relying heavily on loans from the United States of America (which were finally paid off in February 2007) to rebuild its damaged infrastructure. Rationing and conscription dragged on into the post war years, and the country suffered one of the worst winters on record. Nevertheless, morale was boosted by events such as the marriage of Princess Elizabeth in 1947 and the Festival of Britain.

As the country headed into the 1950s, rebuilding continued and a number of immigrants from the remaining British Empire were invited to help the rebuilding effort. As the 1950s wore on, the UK had lost its place as a superpower and could no longer maintain its large Empire. This led to decolonisation, and a withdrawal from almost all of its colonies by 1970. Events such as the Suez Crisis showed that the UK's status had fallen in the world. The 1950s and 1960s were, however, relatively prosperous times after the Second World War, and saw the beginning of a modernisation of the UK, with the construction of its first motorways for example, and also during the 1960s a great cultural movement began which expanded across the world.

British World War II campaigns provide the setting for Call of Duty 1, 2, and 3.

Call of Duty: World at War
Although initially it was thought there was no British campaign in Call of Duty: World at War, the discovery of code within the game showing British weapons hinted one had been planned but dropped last minute. Notably the icon for the weapon selection menu and HUD icon portraying the Bren gun are still in the game's files. Evidence of the Sten gun and Lee-Enfield rife has also been found. There is, however, a British campaign in Call of Duty: World at War: Final Fronts and Call of Duty: World at War DS.

Counter-terrorism in Ukraine (1996)
The British Special Air Service attempted an assassination on Russian Ultranationalist terrorist Imran Zakhaev in the Chernobyl Zone of Alienation in a flashback sequence in Call of Duty 4.

Second Russian Civil War (2011)
The British Special Air Service is involved with United States Marines and Russian Loyalists in covert operations against the Russian Ultranationalists and Middle Eastern OpFor in the Bering Strait, Russia, and Azerbaijan in the majority of the Call of Duty 4 plot.

Russian-American War (2016)
Numerous British operatives are seen as a part of Task Force 141, an elite paramilitary group dedicated to continuing their fight against the Russian Ultranationalists.
