This entailed the armed forces often constituting a major component in peacekeeping and humanitarian missions under

While NATO obligations took increased prominence, Britain nonetheless found itself engaged in a number of low-intensity conflicts, including a spate of insurgencies against colonial occupation. However the Dhofar Rebellion (1962–1976) and The Troubles (1969–1998) emerged as the primary operational concerns of the armed forces. Perhaps the most important conflict during

The United Kingdom, France and Italy formed
25896-436: The world where required to guard against invasion or rebellion, reinforced in some colonies by locally raised reserve forces. In colonies where there was no strategic requirement, regular forces were rarely stationed, with local governments encouraged to maintain and fund military reserve units as contributions to their own defence (although these units were ultimately under the control of the national, i.e. British, Government via
26062-554: Was invaded by Germany. The United States started strategic planning to prepare for a full-scale offensive against Germany. At the end of September 1940, the Tripartite Pact formally united Japan, Italy, and Germany as the Axis powers . The Tripartite Pact stipulated that any country—with the exception of the Soviet Union—that attacked any Axis Power would be forced to go to war against all three. The Axis expanded in November 1940 when Hungary , Slovakia , and Romania joined. Romania and Hungary later made major contributions to
26228-672: Was a mounted force that could be mobilised in times of war or emergency. Volunteer Force units were also frequently raised during wartime, which did not rely on compulsory service and hence attracted recruits keen to avoid the Militia. These were seen as a useful way to add to military strength economically during wartime, but otherwise as a drain on the Militia and so were not normally maintained in peacetime, although in Bermuda prominent propertied men were still appointed Captains of Forts , taking charge of maintaining and commanding fortified coastal artillery batteries and manned by volunteers (reinforced in wartime by embodied militiamen), defending
26394-572: Was only one. The oldest of these organisations was the Militia Force (also referred to as the Constitutional Force ), which (in the Kingdom of England ) was originally the main military defensive force (there otherwise were originally only royal bodyguards, including the Yeomen Warders and the Yeomen of the Guard , with armies raised only temporarily for expeditions overseas), made up of civilians embodied for annual training or emergencies, and had used various schemes of compulsory service during different periods of its long existence. The Militia
26560-407: Was originally a separate force from these, but absorbed the Ordnance Military Corps and various previously civilian departments after the Board of Ordnance was abolished in 1855. The Reserve Forces (which referred to the Home Yeomanry, Militia and Volunteer Forces before the 1859 creation of the British Army Regular Reserve by Secretary of State for War Sidney Herbert , and re-organised under
26726-405: Was originally an all infantry force, organised at the city or county level, and members were not required to serve outside of their recruitment area, although the area within which militia units in Britain could be posted was increased to anywhere in the Britain during the 18th century, and Militia coastal artillery , field artillery, and engineers units were introduced from the 1850s. The Yeomanry
26892-440: Was permanently suspended after the First World War (although a handful of Militia units survived in the United Kingdom, its colonies, and the Crown Dependencies). Unlike the Home, Imperial Fortress and Crown Dependency Militia and Volunteer units and forces that continued to exist after the First World War, although parts of the British military, most were not considered parts of the British Army unless they received Army funds (as
27058-403: Was postponed until the spring of 1940 due to bad weather. After the outbreak of war in Poland, Stalin threatened Estonia , Latvia , and Lithuania with military invasion, forcing the three Baltic countries to sign pacts allowing the creation of Soviet military bases in these countries; in October 1939, significant Soviet military contingents were moved there. Finland refused to sign
27224-657: Was repulsed with heavy Italian casualties; the campaign ended within months with minor territorial changes. To assist Italy and prevent Britain from gaining a foothold, Germany prepared to invade the Balkans, which would threaten Romanian oil fields and strike against British dominance of the Mediterranean. In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa . The offensives were successful; by early February 1941, Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken prisoner. The Italian Navy also suffered significant defeats, with
27390-441: Was required to go through the bureaucracy of the League of Nations, which rendered it essentially toothless. The United States, concerned with events in Europe and Asia, passed the Neutrality Act in August of the same year. Hitler defied the Versailles and Locarno Treaties by remilitarising the Rhineland in March 1936, encountering little opposition due to the policy of appeasement . In October 1936, Germany and Italy formed
27556-433: Was the case for the Bermuda Militia Artillery and the Bermuda Volunteer Rifle Corps ), which was generally only the case for those in the Channel Islands or the Imperial Fortress colonies (Nova Scotia, before Canadian confederation , Bermuda, Gibraltar, and Malta). Today, the British Army is the only Home British military force (unless the Army Cadet Force and the Combined Cadet Force are considered), including both
