The British Armed Forces, also known as Her Majesty's Armed Forces, are the military services responsible for the defence of the United Kingdom, its Overseas Territories and the Crown Dependencies. They also promote the UK's wider interests, support international peacekeeping efforts and provide humanitarian aid.
The Army Reserve is the active-duty volunteer reserve force of the British Army. It is separate from the Regular Reserve whose members are ex-Regular personnel who retain a statutory liability for service. The Army Reserve was known as the Territorial Force from 1908 to 1921, the Territorial Army (TA) from 1921 to 1967, the Territorial and Army Volunteer Reserve (TAVR) from 1967 to 1979, and again the Territorial Army (TA) from 1979 to 2014.
The Territorial Force was a part-time volunteer component of the British Army, created in 1908 to augment British land forces without resorting to conscription. The new organisation consolidated the 19th-century Volunteer Force and yeomanry into a unified auxiliary, commanded by the War Office and administered by local County Territorial Associations. The Territorial Force was designed to reinforce the regular army in expeditionary operations abroad, but because of political opposition it was assigned to home defence. Members were liable for service anywhere in the UK and could not be compelled to serve overseas. In the first two months of the First World War, territorials volunteered for foreign service in significant numbers, allowing territorial units to be deployed abroad. They saw their first action on the Western Front during the initial German offensive of 1914, and the force filled the gap between the near destruction of the regular army that year and the arrival of the New Army in 1915. Territorial units were deployed to Gallipoli in 1915 and, following the failure of that campaign, provided the bulk of the British contribution to allied forces in the Sinai and Palestine Campaign. By the war's end, the Territorial Force had fielded twenty-three infantry divisions and two mounted divisions on foreign soil. It was demobilised after the war and reconstituted in 1921 as the Territorial Army.
The British Indian Army, commonly referred to as the Indian Army, was the main military of the British Indian Empire before its decommissioning in 1947. It was responsible for the defence of the British Indian Empire, including the princely states, which could also have their own armies. The Indian Army was an important part of the British Empire's forces, both in India and abroad, particularly during the First World War and the Second World War.
The Ceylon Defence Force (CDF) was established in 1910 by the Ceylonese legislation Ceylon Defence Force Ordinance, which reformed the Ceylon Volunteer Force (CVF) that existed previously as the military reserve in the British Crown colony of Ceylon. At the time of forming it was only a reserve force but soon developed into a regular force responsible for the defence of Ceylon. The CDF was under the command of the General Officer Commanding, Ceylon of the British Army in Ceylon if mobilised. However mobilisation could be carried out only under orders from the Governor.
Auxiliaries are support personnel that assist the military or police but are organised differently from regular forces. Auxiliary may be military volunteers undertaking support functions or performing certain duties such as garrison troops, usually on a part-time basis. Unlike a military reserve force, an auxiliary force does not necessarily have the same degree of training or ranking structure as regular soldiers, and it may or may not be integrated into a fighting force. Some auxiliaries, however, are militias composed of former active duty military personnel and actually have better training and combat experience than their regular counterparts.
The Royal Hong Kong Regiment , formed in May 1854, was a local auxiliary militia force funded and administered by the colonial Government of Hong Kong. Its powers and duties were mandated by the Royal Hong Kong Regiment Ordnance.
The Home Counties Division was an infantry division of the Territorial Force, part of the British Army, that was raised in 1908. As the name suggests, the division recruited in the Home Counties, particularly Kent, Middlesex, Surrey and Sussex.

It could be awarded after ten years of meritorious service to officers, airmen and airwomen in the Auxiliary and Volunteer Air Forces of the United Kingdom and the Territorial Air Forces and Air Force Reserves of the Dominions, the Indian Empire, Burma, the Colonies and Protectorates.
The Territorial Army (TA) of India is an auxiliary military organisation of part-time volunteers that provides support service to the Indian Army. It is composed of commissioned and non-commissioned officers and other personnel who hold civilian and military occupations. Its role is to "relieve the regular army from static duties and assist civil administration in dealing with natural calamities and maintenance of essential services" and to "provide units for regular army as and when required".
The Efficiency Medal was instituted in 1930 for award to part-time warrant officers, non-commissioned officers and men after twelve years of efficient service on the active list of the Militia or the Territorial Army of the United Kingdom, or of the other Auxiliary Military Forces throughout the British Empire. At the same time a clasp was instituted for award to holders of the medal upon completion of further periods of six years of efficient service.
The Efficiency Decoration, post-nominal letters TD for recipients serving in the Territorial Army of the United Kingdom or ED for those serving in the Auxiliary Military Forces, was instituted in 1930 for award to part-time officers after twenty years of service as an efficient and thoroughly capable officer. The decoration superseded the Volunteer Officers' Decoration, the Colonial Auxiliary Forces Officers' Decoration and the Territorial Decoration.
The Haldane Reforms were a series of far-ranging reforms of the British Army made from 1906 to 1912, and named after the Secretary of State for War, Richard Burdon Haldane. They were the first major reforms since the "Childers Reforms" of the early 1880s, and were made in the light of lessons newly learned in the Second Boer War.
The Indian Defence Force (IDF) was a part-time defence force established as part of the Indian Army in 1917 in order to release regular troops from garrison duties during the First World War.
The Auxiliary Force (India) (AFI) was a part-time, paid volunteer military organisation within the British Indian Army, with recruits from British India.

The Nilgiri Malabar Battalion (NMB) was an Auxiliary Force (India) of the British Colonial Auxiliary Forces of the British Indian Army, composed of Eurasians/Anglo-Indians. Enrollment in the Auxiliary Force was open to all European British subjects and to persons of European descent. After the Mutiny of 1857, a Volunteer Force was created, whose primary function was to protect British families in India. The Volunteer Force units were later absorbed into the Auxiliary Force India, which was created in 1920 for internal security duties. Its terms of service were similar to the Territorial Army of the UK. The Auxiliary Force India, which provided officers to the Army during World War II, was disbanded in 1947.
The Colonial Auxiliary Forces Officers' Decoration, post-nominal letters VD, was established in 1899 as recognition for long and meritorious service as a part-time commissioned officer in any of the organized military forces of the British Colonies, Dependencies and Protectorates. It superseded the Volunteer Officers' Decoration for India and the Colonies in all these territories, but not in the Indian Empire.
56th (Cornwall) Heavy Anti-Aircraft Regiment, Royal Artillery was a volunteer air defence regiment of Britain's Territorial Army (TA). Originally raised in 1920 as a medium artillery regiment, it was converted to the anti-aircraft role in 1932. During the Second World War, it was employed in Home Defence, in Iceland and then in India, where it was temporarily converted back to medium artillery. Postwar, it reverted to air defence until disbandment in 1955.
The Colonial Auxiliary Forces Long Service Medal was instituted by Queen Victoria in 1899 as a military long service award for part-time members of all ranks in any of the organized military forces of the British Colonies, Dependencies and Protectorates throughout the British Empire.
