{{British Army}}

The '''British Army''' is the principal [[Army|land warfare force]] of the [[United Kingdom]]. {{as of|2025|1|1|post=,}} the British Army comprises 73,847 regular full-time personnel, 4,127 [[Brigade of Gurkhas|Gurkhas]], 25,742 [[Army Reserve (United Kingdom)|volunteer reserve]] personnel and 4,697 "other personnel", for a total of 108,413.<ref>{{Cite web |date=3 March 2025 |title=Quarterly service personnel statistics 1 January 2025 |url=https://www.gov.uk/government/statistics/quarterly-service-personnel-statistics-2025 |website=gov.uk}}</ref>

The British Army traces back to 1707 and the [[Acts of Union 1707|formation]] of the united [[Kingdom of Great Britain]] which joined the Kingdoms of [[Kingdom of England|England]] and [[Kingdom of Scotland|Scotland]] into a [[Political union|single state]] and, with that, united the [[English Army]] and the [[Scots Army]] as the British Army.<ref>{{Cite book|url=https://books.google.com/books?id=zDxnAAAAMAAJ&q=%22british+army%22+1660|title=Redcoats and courtesans: the birth of the British Army (1660–1690)|last=Williams|first=Noel T.

At its inception, being composed primarily of cavalry and infantry, the British Army was one of two ''Regular'' Forces (there were also separate ''Reserve Forces'') within the British military (those parts of the British Armed Forces tasked with land warfare, as opposed to the naval forces),<ref>{{Cite web|url=https://api.parliament.uk/historic-hansard/commons/1917/feb/12/naval-and-military-pensions-and-grants|date=12 February 1917|title=Naval and Military Pensions and Grants  |website=[[Hansard|Parliamentary Debates (Hansard)]]}}</ref> with the other having been the ''Ordnance Military Corps'' (made up of the [[Royal Artillery]], [[Royal Engineers]], and the [[Royal Sappers and Miners]]) of the [[Board of Ordnance]], which along with the originally civilian [[Commissariat#19th century|Commissariat Department]], stores and supply departments, as well as barracks and other departments, were absorbed into the British Army when the Board of Ordnance was abolished in 1855.

Until the [[Wars of the Three Kingdoms|Wars of the Three Kingdoms (1639–1653)]], neither England nor Scotland had had a [[standing army]] with professional officers and career corporals and sergeants. England relied on [[Militia (English)|militia]] organised by local officials or private forces mobilised by the nobility, or on hired mercenaries from Europe.<ref>David G. Chandler, ed., ''The Oxford history of the British army'' (1996) pp. 24–45.</ref> From the [[later Middle Ages]] until the Wars of the Three Kingdoms, when a foreign expeditionary force was needed, such as the one that [[Henry V of England]] took to France and that fought at the [[Battle of Agincourt]] (1415), the army, a professional one, was raised for the duration of the expedition.<ref>{{cite web|url=http://blog.nationalarchives.gov.uk/blog/victorious-army-making-raising-king-henry-vs-army-1415/|title=A victorious army in the making: Raising King Henry V's army of 1415|date=11 August 2015|first=Benjamin|last=Trowbridge|publisher=National Archives|access-date=17 October 2017|archive-url=https://web.archive.org/web/20171018013732/http://blog.nationalarchives.gov.uk/blog/victorious-army-making-raising-king-henry-vs-army-1415/|archive-date=18 October 2017|url-status=live}}</ref>

During the Wars of the Three Kingdoms, the members of the English [[Long Parliament]] realised that the use of county militia organised into regional associations (such as the [[Eastern Association]]), often commanded by local members of Parliament (both from the House of Commons and the House of Lords), while more than able to hold their own in the regions which [[Parliamentarians (English Civil War)|Parliamentarians ('Roundheads")]] controlled, were unlikely to win the war. So Parliament initiated two actions. The [[Self-denying Ordinance]] forbade members of Parliament (with the notable exception of [[Oliver Cromwell]], then a member of parliament and future Lord Protector) from serving as officers in the Parliamentary armies. This created a distinction between the civilians in Parliament, who tended to be [[Presbyterianism|Presbyterian]] and conciliatory to the Royalists ("Cavaliers") in nature, and a corps of professional officers, who tended to be Independent ([[Congregational]]) in theology. The second action was legislation for the creation of a Parliamentary-funded army, commanded by Lord General [[Thomas Fairfax]], which became known as the [[New Model Army]] (originally phrased "new-modelled Army").{{sfn|Rogers|1968|pp=207–211}}

While this proved to be a war-winning formula, the New Model Army, being organised and politically active, went on to dominate the politics of the [[Interregnum (England)|Interregnum]] and by 1660 was widely disliked. The New Model Army was paid off and disbanded at the later [[Restoration (1660)|Restoration]] of the monarchy in 1660 with the accession of King [[Charles II of England|Charles II]]. For many decades the alleged excesses of the New Model Army under [[the Protectorate]]  / Commonwealth under Oliver Cromwell were used as propaganda (and still feature in Irish folklore){{sfn|Ó Siochrú|2008|p=1–2}} and the [[Whig Party (England)|Whig Party]] element recoiled from allowing a standing army to continue with the agreed-upon rights and privileges under the return of a king.<ref>Lord Macaulay ''The History of England from the accession of James the Second'' (C.H. Firth ed. 1913) 1:136–38</ref> The militia acts of 1661 and 1662 prevented local authorities from calling up militia and oppressing their own local opponents. Calling up the militia was possible only if the king and local elites agreed to do so.<ref>{{cite web|title= 'Charles II, 1661: An Act declaring the sole Right of the Militia to be in King and for the present ordering & disposing the same.', Statutes of the Realm: volume 5: 1628–80 (1819)|pages=308–309|url= http://www.british-history.ac.uk/report.asp?compid=47290|access-date= 5 March 2007|archive-url= https://web.archive.org/web/20070927215615/http://www.british-history.ac.uk/report.asp?compid=47290|archive-date= 27 September 2007|url-status= live}}</ref>

[[Charles II of England|King Charles II]] and his "[[Cavalier]]" / Royalist supporters favoured a new army under royal control, and immediately after the Restoration of 1660 to 1661 began working on its establishment.<ref>David Chandler, ''The Oxford History of the British Army'' (2003) p. 46.

After the Restoration, King Charles II pulled together four regiments of infantry and cavalry, calling them his guards, at a cost of £122,000 from his general budget. This became the foundation of the permanent English Army. By 1685, it had grown to number 7,500 soldiers in marching regiments, and 1,400 men permanently stationed in garrisons. A [[Monmouth Rebellion]] in 1685 allowed successor King  [[James II of England|James II]] to raise the forces to 20,000 men. There were 37,000 in 1678, when England played a role in the closing stage of the cross-channel [[Franco-Dutch War]]. After [[Protestantism|Protestant]] dual Monarchs [[William III of England|William III]], formerly William of the Dutch [[House of Orange]], and his wife [[Mary II of England|Mary II's]] joint accession to the throne after a short constitutional crisis with Parliament sending  Mary's father, predecessor King James II, (who remained a Catholic) during his brief controversial reign, off the throne and into exile.  England then involved itself in the [[War of the Grand Alliance]] on the Continent, primarily to prevent a possible French  Catholic monarch organizing an invasion restoring the exiled James II (Queen Mary's father and still a [[Roman Catholic]]).<ref>{{harvnb|Miller|2000|p=144}}</ref> Later in 1689, William III to solidify his and Mary's hold on the monarchy, expanded the new English army to 74,000, and then a few years later to 94,000 in 1694. Parliament was very nervous and reduced the cadre to 70,000 in 1697. Scotland and Ireland had theoretically separate military establishments, but they were unofficially merged with the English Crown  force.<ref>Chandler, ed., ''The Oxford history of the British army'' (1996) pp. 46–57.</ref><ref>Correlli Barnett, ''Britain and her army, 1509–1970: a military, political and social survey'' (1970) pp. 90–98, 110–125.</ref>

[[File:John Churchill Marlborough porträtterad av Adriaen van der Werff (1659-1722).jpg|thumb|alt=Oil-on-canvas portrait|[[John Churchill, 1st Duke of Marlborough]], was one of the first generals in the new British Army and fought in the War of the Spanish Succession. He was a noted ancestor of Sir [[Winston S. Churchill]], later famous [[Prime Minister of the United Kingdom|Prime Minister]] during [[World War II]].]]

By the time of the 1707 [[Acts of Union 1707|Acts of Union]], many regiments of the English and Scottish armies were combined under one operational command and stationed in the [[Netherlands]] for the [[War of the Spanish Succession]]. Although all the regiments were now part of the new British military establishment,<ref name=Chandler2003>{{cite book|last1=Chandler|first1=David|title=The Oxford history of the British Army|date=2003|publisher=Oxford University Press|isbn=978-0-19-280311-5|page=xv|url=https://books.google.com/books?id=ZOgs8WpJI9AC&q=British+army+from+the+Act+of+Union&pg=PA45|quote=It is generally accepted that the regular standing army in Britain was officially created – in the sense of being fully accommodated within parliamentary control in 1689, although it is, strictly speaking, only correct to refer to the British army from the Act of Union with Scotland in 1707.}}</ref> they remained under the old operational-command structure and retained much of the institutional ethos, customs and traditions of the standing armies created shortly after the [[restoration (England)|Restoration of the Monarchy]] 47 years earlier. The order of seniority of the most-senior British Army line regiments is based on that of the earlier English army. Although technically the Scots [[Royal Regiment of Foot]] was raised in 1633 and is the oldest Regiment of the Line,<ref>{{cite web|title=History|url=http://www.army.mod.uk/infantry/23301.aspx|publisher=British Army|access-date=12 January 2017|archive-url=https://web.archive.org/web/20170118061954/http://www.army.mod.uk/infantry/23301.aspx|archive-date=18 January 2017|url-status=live}}</ref> Scottish and Irish regiments were only allowed to take a rank in the English army on the date of their arrival in England (or the date when they were first placed on the English establishment). In 1694, a board of general officers was convened to decide the rank of English, Irish and Scots regiments serving in the Netherlands; the regiment which became known as the [[Scots Greys]] were designated the [[4th Royal Irish Dragoon Guards|4th Dragoons]] because there were three English regiments raised prior to 1688 when the Scots Greys were first placed in the English establishment. In 1713, when a new board of general officers was convened to decide the rank of several regiments, the seniority of the Scots Greys was reassessed and based on their June 1685 entry into England. At that time there was only one English regiment of dragoons, and the Scots Greys eventually received the British Army rank of 2nd Dragoons.{{sfn|Royal Scots Greys|1840|pp=56–57}}

After 1707, British continental policy was to contain expansion by competing powers such as France and Spain. Although Spain was the dominant global power during the previous two centuries and the chief threat to England's early trans-Atlantic colonial ambitions, its influence was now waning.

The British Army was heavily involved in the [[Napoleonic Wars]], participating in a number of campaigns in Europe (including continuous deployment in the [[Peninsular War]]), the [[Caribbean]], North Africa and [[War of 1812|North America]]. The war between the British and the [[First French Empire]] of [[Napoleon Bonaparte]] stretched around the world; at its peak in 1813, the regular army contained over 250,000 men. A coalition of Anglo-Dutch and Prussian armies under the [[Duke of Wellington]] and [[Field Marshal von Blücher]] finally defeated Napoleon at [[Battle of Waterloo|Waterloo]] in 1815.<ref>{{harvnb|Mallinson|2009|p=177}}.</ref>

The English were involved politically and militarily in Ireland. The campaign of English republican Protector [[Oliver Cromwell]] involved uncompromising treatment of the Irish towns (most notably [[Drogheda]] and [[Wexford]]) which supported the Royalists during the [[English Civil War]]. The English Army (and the subsequent British Army) remained in Ireland primarily to suppress Irish revolts or disorder. In addition to its conflict with Irish nationalists, it was faced with the prospect of battling Anglo-Irish and [[Ulster Scots people|Ulster Scots]] in Ireland who were angered by unfavourable taxation of Irish produce imported into Britain. With other Irish groups, they raised a volunteer army and threatened to emulate the American colonists if their conditions were not met. Learning from their experience in America, the British government sought a political solution. The British Army fought Irish rebels—Protestant and Catholic—primarily in [[Ulster]] and [[Leinster]] ([[Theobald Wolfe Tone|Wolfe Tone's]] [[United Irishmen]]) in the [[Irish Rebellion of 1798|1798 rebellion]].<ref>[https://www.bbc.co.uk/history/british/empire_seapower/irish_reb_01.shtml The 1798 Irish Rebellion] {{Webarchive|url=https://web.archive.org/web/20110207080021/http://www.bbc.co.uk/history/british/empire_seapower/irish_reb_01.shtml |date=7 February 2011 }} BBC</ref>

[[File:Establishment and Strength of the British Army (excluding Indian native troops stationed in India) prior to August, 1914.jpg|thumb|Establishment and strength of the British Army, excluding Indian native troops stationed in India, prior to August 1914]]
Inspired by the successes of the [[Prussian Army]] (which relied on short-term conscription of all eligible young men to maintain a large reserve of recently discharged soldiers, ready to be recalled on the outbreak of war to immediately bring the small peacetime regular army up to strength), the [[Regular Reserve (United Kingdom)#Army Reserve (Regular)|''Regular Reserve'']] of the British Army was originally created in 1859 by [[Secretary of State for War]] [[Sidney Herbert, 1st Baron Herbert of Lea|Sidney Herbert]], and re-organised under the [[Reserve Force Act 1867]]. Prior to this, a soldier was generally enlisted into the British Army for a 21-year engagement, following which (should he survive so long) he was discharged as a Pensioner. Pensioners were sometimes still employed on garrison duties, as were younger soldiers no longer deemed fit for expeditionary service who were generally organised in invalid units or returned to the regimental depot for home service. The cost of paying pensioners, and the obligation the government was under to continue to employ invalids as well as soldiers deemed by their commanding officers as detriments to their units were motivations to change this system. The long period of engagement also discouraged many potential recruits. The long service enlistments were consequently replaced with short service enlistments, with undesirable soldiers not permitted to re-engage on the completion of their first engagement. The size of the army also fluctuated greatly, increasing in war time, and drastically shrinking with peace. Battalions posted on garrison duty overseas were allowed an increase on their normal peacetime establishment, which resulted in their having surplus men on their return to a ''Home'' station. Consequently, soldiers engaging on short term enlistments were enabled to serve several years with the colours and the remainder in the Regular Reserve, remaining liable for recall to the colours if required. Among the other benefits, this thereby enabled the British Army to have a ready pool of recently trained men to draw upon in an emergency. The name of the Regular Reserve (which for a time was divided into a ''First Class'' and a ''Second Class'') has resulted in confusion with the ''Reserve Forces'', which were the pre-existing part-time, local-service home-defence [[Units of the British Army#British Army units in other areas of the British Armed Forces|forces]] that were auxiliary to the British Army (or ''Regular Force''), but not originally part of it: the [[Yeomanry]], [[Militia (United Kingdom)|Militia]] (or ''Constitutional Force'') and [[Volunteer Force]]. These were consequently also referred to as ''Auxiliary Forces'' or ''Local Forces''.<ref>''The Army Book For The British Empire'', by Lieutenant-General WH Goodenough, Royal Artillery, CB, and Lieutenant-Colonel JC Dalton (HP), Royal Artillery. Her Majesty's Stationery Office, London. 1893.</ref>

The late-19th-century [[Cardwell Reforms|Cardwell]] and [[Childers Reforms]]  gave the army its modern shape and redefined its [[regimental system]].<ref>{{London Gazette|issue=24992|page=3300|date=1 July 1881}}</ref> The 1907 [[Haldane Reforms]] created the [[Territorial Force]] as the army's volunteer reserve component, merging and reorganising the Volunteer Force and Yeomanry, while the Militia was replaced by the Special Reserve.<ref>{{harvnb|Cassidy|2006|p=79}}.</ref>

Great Britain was challenged by other powers, primarily the [[German Empire]] and [[Nazi Germany]], during the 20th century. A century earlier it vied with Napoleonic France for global pre-eminence, and [[House of Hanover|Hanoverian]] Britain's natural allies were the kingdoms and principalities of [[northern Germany]]. By the middle of the 19th century, Britain and France were allies in preventing Russia's appropriation of the [[Ottoman Empire]], although the fear of French invasion led shortly afterwards to the creation of the Volunteer Force. By the first decade of the 20th century, the United Kingdom was allied with France (by the [[Entente Cordiale]]) and Russia (which had a secret agreement with France for mutual support in a war against the [[Prussia]]n-led German Empire and the [[Austro-Hungarian Empire]]).<ref>{{cite web|url=http://wwi.lib.byu.edu/index.php/The_Anglo-Russian_Entente|title=Agreement concerning Persia|access-date=23 July 2016|archive-url=https://web.archive.org/web/20160708181007/https://wwi.lib.byu.edu/index.php/The_Anglo-Russian_Entente|archive-date=8 July 2016|url-status=live}}</ref>

When the First World War broke out in August 1914 the British Army sent the [[British Expeditionary Force (World War I)|British Expeditionary Force]] (BEF), consisting mainly of [[Standing army|regular army]] troops, to [[Western Front (World War I)|France and Belgium]].<ref>{{harvnb|Ensor|1980|pp=525–526}}.</ref> The fighting bogged down into static [[trench warfare]] for the remainder of the war.

The First World War was the most devastating in [[Military history of the United Kingdom|British military history]], with nearly 800,000 men killed and over two&nbsp;million wounded. Early in the war, the BEF was virtually destroyed and was replaced first by [[Kitchener's Army|volunteers]] and then by a [[Conscription in the United Kingdom|conscript]] force.

{{main|List of equipment of the British Army}}

=== Infantry ===
The British Army's basic weapon is the 5.56&nbsp;mm [[SA80|L85A2 or L85A3]] assault rifle, with some specialist personnel using the L22A2 carbine variant (pilots and some tank crew). The weapon was traditionally equipped with either [[iron sights]] or an optical [[SUSAT]], although other optical sights have been subsequently purchased to supplement these.<ref>{{cite web|url=http://www.army.mod.uk/equipment/23222.aspx|title=The British Army – SA80 individual weapon|website=www.army.mod.uk|url-status=live|archive-url=https://web.archive.org/web/20170616184526/http://army.mod.uk/equipment/23222.aspx|archive-date=16 June 2017|access-date=9 February 2017}}</ref> The weapon can be enhanced further utilising the [[Picatinny rail]] with attachments such as the [[L17A2 UGL|L17A2]] under-barrel grenade launcher.<ref name=":8">{{Cite web|url=https://www.army.mod.uk/equipment/small-arms-and-support-weapons/|title=Small arms and support weapons|website=www.army.mod.uk|access-date=12 February 2020}}</ref> In 2023, the [[Army Special Operations Brigade]], which includes the [[Ranger Regiment (United Kingdom)|Ranger Regiment]], began using the [[L403A1]], an [[M16 rifle|AR-pattern]] rifle also used by the [[Royal Marines]].<ref>{{cite web|url=https://www.army.mod.uk/news-and-events/news/2023/09/newadvancedrifle/| access-date=2023-10-20| date=2023-09-07| title=New advanced rifle for Ranger Regiment| website=www.army.mod.uk}}</ref>

Some soldiers are equipped with the 7.62mm [[L129A1|L129A1 sharpshooter rifle]],<ref>{{cite web|url=https://www.army.mod.uk/equipment/small-arms-and-support-weapons/|title=L129A1 sharpshooter Rifle|url-status=live|archive-url=https://web.archive.org/web/20180612140733/https://www.army.mod.uk/equipment/small-arms-and-support-weapons/|archive-date=12 June 2018}}</ref> which in 2018 formally replaced the [[L86 LSW|L86A2]] Light Support Weapon. Support fire is provided by the [[L7 (machine gun)|L7 general-purpose machine gun]] (GPMG),<ref>{{cite web|url=http://www.army.mod.uk/equipment/23226.aspx|title=The British Army – General purpose machine gun|website=www.army.mod.uk|access-date=9 March 2017|archive-url=https://web.archive.org/web/20170126172854/http://www.army.mod.uk/equipment/23226.aspx|archive-date=26 January 2017|url-status=live}}</ref> and indirect fire is provided by [[L16 81mm mortar]]s. Sniper rifles include the [[Accuracy International Arctic Warfare|L118A1]]&nbsp;7.62&nbsp;mm, [[L115A3]] and the [[AW50F]], all manufactured by [[Accuracy International]].<ref>{{cite web|url=http://www.army.mod.uk/equipment/23223.aspx|title=The British Army – L115A3 Long range 'sniper' rifle|website=www.army.mod.uk|access-date=9 March 2017|archive-url=https://web.archive.org/web/20170410084543/http://www.army.mod.uk/equipment/23223.aspx|archive-date=10 April 2017|url-status=live}}</ref> The British Army utilises the [[Glock|Glock 17]] as its side arm.<ref name=":8" />

Anti tank guided weapons include the [[FGM-148 Javelin|Javelin]], the medium range anti-tank guided weapon replacement for [[MILAN|Milan]], with overfly and direct attack modes of operation, and the [[NLAW]]. The Next-generation Light Anti-tank Weapon ([[NLAW]]) is the first, non-expert, short-range, anti-tank missile that rapidly knocks out any main battle tank in just one shot by striking it from above.<ref>{{Cite web |title= NLAW |url= https://www.saab.com/products/nlaw |url-status= live |archive-url= https://web.archive.org/web/20220227124742/https://www.saab.com/products/nlaw |archive-date= 27 February 2022 |access-date=28 February 2022 |publisher=[[Saab AB]] |publication-place=Stockholm, [[Sweden|SE]]}}</ref>

=== Artillery ===
The army has three main artillery systems: the [[M270 multiple launch rocket system]] (MLRS), the [[Archer artillery system|Archer]] and the [[L118 light gun]].<ref>{{cite web|url=http://www.army.mod.uk/equipment/23208.aspx|title=The British Army – Artillery and air defence|website=www.army.mod.uk|access-date=9 March 2017|archive-url=https://web.archive.org/web/20170410084443/http://www.army.mod.uk/equipment/23208.aspx|archive-date=10 April 2017|url-status=live}}</ref> The MLRS, first used in [[Operation Granby]], has an {{convert|85|km|adj=on}} standard range, or with the [[Precision Strike Missile|PrSM]], up to 500&nbsp;km.<ref>{{Cite news|url=http://www.thinkdefence.co.uk/uk-complex-weapons/guided-multiple-launch-rocket-system-gmlrs/|title=Guided Multiple Launch Rocket System (GMLRS) – Think Defence|work=Think Defence|access-date=17 March 2017|archive-url=https://web.archive.org/web/20170318084429/http://www.thinkdefence.co.uk/uk-complex-weapons/guided-multiple-launch-rocket-system-gmlrs/|archive-date=18 March 2017|url-status=live}}</ref> The Archer is a 155&nbsp;mm self-propelled armoured gun with a {{convert|50|km|adj=on}} range.

=== Protected mobility ===
Where armour is not required or mobility and speed are favoured the British Army utilises protected patrol vehicles, such as the Panther variant of the [[Iveco LMV]], the [[Ocelot (vehicle)|Foxhound]], and variants of the [[Cougar (MRAP)|Cougar]] family (such as the Ridgeback, Husky and Mastiff).<ref>{{cite web|url=http://www.army.mod.uk/equipment/23235.aspx|title=The British Army – Protected patrol vehicles|website=www.army.mod.uk|access-date=9 March 2017|archive-url=https://web.archive.org/web/20170410084656/http://www.army.mod.uk/equipment/23235.aspx|archive-date=10 April 2017|url-status=live}}</ref> For day-to-day utility work the army commonly uses the [[Land Rover Wolf]], which is based on the [[Land Rover Defender]].<ref>{{cite web|url=http://www.landrover.com/gb/en/lr/defender/|title=Land Rover Defender|publisher=Landrover.com|access-date=28 March 2011|url-status=dead|archive-url=https://web.archive.org/web/20110405215951/http://www.landrover.com/gb/en/lr/defender/|archive-date=5 April 2011}}</ref>

The British Government considered Bermuda as an [[Imperial fortress]], rather than a colony. After the French Revolution, the [[Governor of Bermuda]] was normally a military officer (usually a Lieutenant-General or Major-General of the Royal Artillery or Royal Engineers) in charge of all military forces in Bermuda, with the Bermuda Garrison falling under the Nova Scotia Command. From 1868, the Bermuda Garrison became the independent Bermuda Command, with Governors being Generals, Lieutenant-Generals or Major Generals occupying the role of Commander-in-Chief or [[General officer commanding#GOC-in-C|General Officer Commanding-in-Chief]] (GOC-in-C). Locally recruited reserve units, the Royal Artillery-badged [[Bermuda Militia Artillery]] (BMA) and [[Bermuda Volunteer Rifle Corps]] (BVRC) were raised again from 1894, later joined by the Royal Engineers-badged [[Bermuda Volunteer Engineers]] (1931–1946), [[General Service Corps]]-badged [[Bermuda Militia Infantry]] (1939–1946), and a Home Guard (1942–1946). After the [[Royal Naval Dockyard, Bermuda|Royal Naval Dockyard]] was redesignated a naval base in 1951, the army garrison was closed in 1957, leaving only the part-time BMA (re-tasked as infantry in 1953, though still badged and uniformed as Royal Artillery) and BVRC (renamed Bermuda Rifles in 1949). The Bermuda Command Headquarters and all regular army personnel other than members of the Permanent Staff of the local Territorials and the [[Aide-de-Camp]] to the Governor of Bermuda (today normally a Captain from the [[Royal Bermuda Regiment]] employed full-time for the duration of the appointment) were withdrawn. Home defence has been provided by the [[Royal Bermuda Regiment]] since formed by the 1965 amalgamation of the BMA and Bermuda Rifles.<ref>{{cite web|url=https://www.gov.uk/government/news/royal-anglian-soldiers-boost-bermuda-regiment|title=Royal Anglian soldiers boost Bermuda Regiment|publisher=Ministry of Defence|access-date=22 July 2015|archive-url=https://web.archive.org/web/20150723035810/https://www.gov.uk/government/news/royal-anglian-soldiers-boost-bermuda-regiment|archive-date=23 July 2015|url-status=live}}</ref>

=== Colonial units ===
[[File:1939 Dominion and Colonial Regiments.jpg|thumb|upright|left|1939 Dominion and Colonial Regiments]]

The British Army historically included many units from what are now separate [[Commonwealth realm]]s. When the [[English Empire]] was established in [[British America|North America]] (including Bermuda), and the West Indies in the early 17th century there was no standing English Army, only the [[Militia (English)|Militia]], [[Yeomanry]], and [[Sovereign's Bodyguard|Royal bodyguards]], of which the Militia, as the primary home-defence force, was immediately extended to the colonies. [[Militia (British Dominions and Crown Colonies)|Colonial militias]] defended colonies single-handedly at first against indigenous peoples and European competitors. Once the standing English Army, later the British Army, came into existence and began to garrison the colonies, the colonial militias fought side by side with it in a number of wars, including the [[Seven Years' War]]. Some of the colonial militias rebelled during the [[American Revolutionary War|American War of Independence]]. The militia fought alongside the regular British Army (and native allies) in defending British North America from their former countrymen during the [[War of 1812]].<ref>{{cite web |url=http://www.archives.gov.on.ca/en/explore/online/1812/militia.aspx|title=Militia and civilian life |publisher=Government of Ontario |access-date=1 October 2020}}</ref>

Locally raised units in strategically located [[Imperial fortress]] colonies (including: [[Nova Scotia]] before the [[Canadian Confederation]]; [[Bermuda]] – which was treated as part of [[The Maritimes]] under the Commander-in-Chief at Nova Scotia until Canadian Confederation; [[Gibraltar]]; and [[Malta]]) and the [[Channel Islands]] were generally maintained from army funds and more fully integrated into the British Army as evident from their placements in British Army lists, unlike units such as the [[King's African Rifles]].<ref>{{Cite newspaper The Times |title=The Somaliland Operations|date=23 October 1902 |page=6 |issue=36906}}</ref>

The larger colonies (Australia, New Zealand, Canada, South Africa, etc.) mostly achieved [[Dominion|Commonwealth Dominion]] status before or after the First World War and were granted full legislative independence in 1931. While remaining within the British Empire, this placed their governments on a par with the British government, and hence their military units comprised separate armies (e.g. the [[Australian Army]]), although Canada retained the term "militia" for its military forces until the Second World War. From the 1940s, these dominions and many colonies chose full independence, usually becoming [[Commonwealth realm]]s (as member states of the Commonwealth are known today).<ref>{{cite web | title=Statute of Westminster Adoption Act 1942 | work=National Archives of Australia: Documenting a Democracy | url = http://www.foundingdocs.gov.au/item.asp?sdID=96 | access-date=8 August 2005 | url-status=dead |archive-url = https://web.archive.org/web/20050716075624/http://www.foundingdocs.gov.au/item.asp?sdID=96 |archive-date=16 July 2005}}</ref><ref>{{citation |url = https://ottawacitizen.com/opinion/op-ed/Succeeding+Canadian+throne/7651371/story.html|last1=Bowden |first1=James | first2=Philippe |last2=Lagassé | title=Succeeding to the Canadian throne | date=6 December 2012 |newspaper=Ottawa Citizen | access-date=6 December 2012 |url-status=dead |archive-url = https://web.archive.org/web/20130110062651/http://www.ottawacitizen.com/opinion/op-ed/Succeeding%2BCanadian%2Bthrone/7651371/story.html |archive-date=10 January 2013 }}</ref>

=== Levels of Command ===
The structure of the British Army beneath the level of Divisions and Brigades is also hierarchical and command is based on rank. The table below details how many units within the British Army are structured, although there can be considerable variation between individual units:<ref name=":4" />

Whilst many units are organised as Battalions or Regiments administratively, the most common fighting unit is the combined arms unit known as a Battlegroup. This is formed around a combat unit and supported by units (or sub-units) from other capabilities. An example of a battlegroup would be two companies of armoured infantry (e.g. from the 1st Battalion of the [[Mercian Regiment]]), one squadron of heavy armour (e.g. A Squadron of the [[Royal Tank Regiment]]), a company of engineers (e.g. B Company of the 22nd Engineer Regiment), a Battery of artillery (e.g. D Battery of the 1st Regiment of the [[Royal Horse Artillery]]) and smaller attachments from medical, logistic and intelligence units. Typically organised and commanded by a battlegroup headquarters and named after the unit which provided the most combat units, in this example, it would be the 1 Mercian Battlegroup. This creates a self-sustaining mixed formation of armour, infantry, artillery, engineers and support units, commanded by a lieutenant colonel.<ref name="SAS">

The British Army primarily recruits from within the United Kingdom, but accept applications from all British citizens. It also accepts applications from Irish citizens and [[Commonwealth of Nations|Commonwealth]] citizens, with certain restrictions.<ref name=":5">{{Cite web|url=https://apply.army.mod.uk/how-to-join/can-i-join|title=Army entry requirements: Can I join the Army? – British Army Jobs |website=apply.army.mod.uk}}</ref> Since 2018 the British Army has been an equal-opportunity employer (with some legal exceptions due to medical standards), and does not discriminate based on race, religion or sexual orientation.<ref>{{cite web|title=The British Army – Diversity|url=http://www.army.mod.uk/join/Equality-and-diversity.aspx|url-status=live|archive-url=https://web.archive.org/web/20170212094121/http://www.army.mod.uk/join/Equality-and-diversity.aspx|archive-date=12 February 2017|access-date=11 February 2017|website=www.army.mod.uk}}</ref> Applicants for the Regular Army must be a minimum age of 16, although soldiers under 18 may not serve in operations, and the maximum age is 36. Applicants for the Army Reserve must be a minimum of 17 years and 9 months, and a maximum age of 43. Different age limits apply for Officers and those in some specialist roles. Applicants must also meet several other requirements, notably regarding medical health, physical fitness, past-criminal convictions, education, and regarding any tattoos and piercings.<ref name=":5" />

Soldiers and officers in the Regular Army now enlist for an initial period of 12 years, with options to extend if they meet certain requirements. Soldiers and officers are normally required to serve for a minimum of 4 years from date of enlistment and must give 12 months' notice before leaving; soldiers who joined before the age of 18 years old are normally required to serve for a minimum of 6 years.<ref>{{cite web|url=https://www.army.mod.uk/documents/general/TermsofService.pdf|title=British Army Terms of Service|date=April 2015|url-status=dead|archive-url=https://web.archive.org/web/20170623005208/http://www.army.mod.uk/documents/general/TermsofService.pdf|archive-date=23 June 2017}}</ref>

=== Oath of allegiance ===
All soldiers and commissioned officers must take an oath of allegiance upon joining the Army, a process known as attestation. Those who wish to swear by [[God in Abrahamic religions|God]] use the following words:<ref name=":2" />
{{blockquote|I, [soldier's or commissioned officer's name], swear by Almighty God that I will be faithful and bear true allegiance to [[Charles III|His Majesty King Charles III]], his heirs and successors and that I will as in duty bound honestly and faithfully defend His Majesty, his heirs and successors in person, [[British Crown|crown]] and dignity against all enemies and will observe and obey all orders of His Majesty, his heirs, and successors and of the generals and officers set over me.<ref>{{cite web|url=http://www.whodareswins.com/british-army-oath-of-allegiance.html#selfless|title=British Army Oath of Allegiance|access-date=29 November 2010|archive-url=https://web.archive.org/web/20101224084204/http://www.whodareswins.com/british-army-oath-of-allegiance.html#selfless|archive-date=24 December 2010|url-status=live}}</ref>}}

=== Training ===
[[File:RMAS18Je6-4685.jpg|thumb|alt=Red-brick buildings with large windows|New College buildings at Royal Military Academy Sandhurst]]

{{see also|Selection and Training in the British Army|List of British Army installations}}Candidates for the Army undergo common training, beginning with [[Recruit training|initial military training]], to bring all personnel to a similar standard in basic military skills, which is known as Phase 1 training. They then undertake further specialist trade-training for their specific Regiment or Corps, known as Phase 2 training. After completing Phase 1 training a soldier is counted against the Army's trained strength, and upon completion of Phase 2 are counted against the Army's fully trained trade strength.<ref name=boot>{{cite web|url=http://www.armedforces.co.uk/army/listings/l0139.html|title=Recruitment Selection and Training|publisher=Bootcamp|access-date=23 November 2020|archive-date=21 April 2014|archive-url=https://web.archive.org/web/20140421050944/http://www.armedforces.co.uk/army/listings/l0139.html|url-status=dead}}</ref>

== Flags and ensigns ==
{{see also|Regulation Colours}}
The British Army's official flag is the [[Union Jack]]. The Army also has a non-ceremonial flag that is often seen flying from military buildings and is used at recruiting and military events and exhibitions.<ref>{{cite web |url=http://www.britishflags.net/British%20Army.html |title=British Army (non-ceremonial) |publisher=britishflags.net |access-date=22 October 2010 |archive-url=https://web.archive.org/web/20100916084125/http://www.britishflags.net/British%20Army.html |archive-date=16 September 2010 |url-status=usurped }}</ref> Traditionally most British Army units had a set of flags, known as the [[Colours, standards and guidons|colours]]—normally a Regimental Colour and a King's Colour (the Union Jack). Historically these were carried into battle as a rallying point for the soldiers and were closely guarded. In modern units the colours are often prominently displayed, decorated with [[Battle honours of the British and Imperial Armies|battle honours]], and act as a focal point for Regimental pride.<ref>{{Cite web|title=The regimental system {{!}} National Army Museum|url=https://www.nam.ac.uk/explore/regimental-system|access-date=23 November 2020|website=www.nam.ac.uk}}</ref> A soldier re-joining a regiment (upon recall from the reserve) is described as ''re-called to the Colours''.<ref>{{Cite web|url=https://www.royalsignalsmuseum.co.uk/wp-content/uploads/2020/05/20200504_80_Brassard-of-Cpl-Birdsall.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://www.royalsignalsmuseum.co.uk/wp-content/uploads/2020/05/20200504_80_Brassard-of-Cpl-Birdsall.pdf |archive-date=2022-10-09 |url-status=live|title='History of Signalling in 100 Objects: The Brassard of CPL R A Birdsall' (See penultimate sentence: ''Many who served in Korea were reservists recalled to the colours plus a large number of National Servicemen'').

Most ranks across the British Army are known by the same name regardless of which Regiment they are in. However, the [[Household Cavalry]] call many ranks by different names, the [[Royal Artillery]] refer to Corporals as Bombardiers, the Rifles spell Sergeant as Serjeant,<ref>{{Cite web |title=Swift and bold: All about The Rifles |date=2 February 2022 |url=https://www.forces.net/news/swift-and-bold-all-about-rifles}}</ref> and Private soldiers are known by a wide variety of titles; notably trooper, gunner, guardsman, kingsman, sapper, signaller, fusilier, craftsman and rifleman dependant on the Regiment they belong to.<ref>{{Cite web|title=British Army ranks {{!}} National Army Museum|url=https://www.nam.ac.uk/explore/british-army-ranks|access-date=23 November 2020|website=www.nam.ac.uk}}</ref> These names do not affect a soldier's pay or role.<ref>{{Cite web|title=Armed Forces' Pay Review Body: Forty-Ninth Report 2020|url=https://www.gov.uk/government/publications/armed-forces-pay-review-body-forty-ninth-report-2020|access-date=23 November 2020|website=GOV.UK|date=6 August 2020 }}</ref>

==Reserve forces==
{{main|Army Reserve (United Kingdom)}}
The oldest of the Reserve Forces was the [[Militia (Great Britain)|Militia Force]] (also referred to as the ''Constitutional Force''),<ref>{{Cite web |title=Militia Bill. (Hansard, 23 April 1852) |url=https://api.parliament.uk/historic-hansard/commons/1852/apr/23/militia-bill |url-status=live |archive-url=https://web.archive.org/web/20230929100825/https://api.parliament.uk/historic-hansard/commons/1852/apr/23/militia-bill |archive-date=29 September 2023 |access-date=2024-03-04 |website=api.parliament.uk}}</ref><ref>{{Cite web|url=https://api.parliament.uk/historic-hansard/commons/1855/may/04/the-militia|date=4 May 1855|title=THE MILITIA.  |website=[[Hansard|Parliamentary Debates (Hansard)]]}}</ref><ref>{{Cite web|url=https://api.parliament.uk/historic-hansard/lords/1856/jul/11/the-militia-question|date=11 July 1856|title=The Militia-Question |website=[[Hansard|Parliamentary Debates (Hansard)]]}}</ref><ref>{{Cite web|url=https://api.parliament.uk/historic-hansard/commons/1878/jun/13/army-auxiliary-forces-the-militia|date=13 June 1878|title=Army—Auxiliary Forces—The Militia.—Observations  |website=[[Hansard|Parliamentary Debates (Hansard)]]}}</ref> which (in the [[Kingdom of England]], prior to 1707) was originally the main military defensive force (until the 1645 creation of the [[New Model Army]], 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, which had used various schemes of compulsory service during different periods of its long existence. From the 1850s it recruited volunteers who engaged for terms of service. The Militia was originally an all-infantry force, though [[Militia Artillery units of the United Kingdom and Colonies|Militia coastal artillery]], field artillery, and engineers units were introduced from the 1850s.<ref name=autogenerated1>''The Militia Artillery 1852–1909'', by Norman EH Litchfield. The Sherwood Press (Nottingham) Ltd. 1987</ref>

[[Volunteer Force]] units were also frequently raised during wartime and disbanded upon peace. This was re-established as a permanent (i.e., in war and peace) part of the Reserve Forces in 1859. It differed from the Militia in a number of ways, most particularly in that volunteers did not commit to a term service, and were able to resign with fourteen days notice (except while embodied). As volunteer soldiers were originally expected to fund the cost of their own equipment, few tended to come from the labouring class among whom the Militia primarily recruited.<ref>{{cite web |url=https://www.nam.ac.uk/explore/civilian-soldiers |title=Civilian soldiers |author=<!--Not stated--> |date=<!--Not stated--> |website=National Army Museum |access-date=9 September 2021 |quote=Troop shortages and patriotic zest during the imperial crises and expansion of the British Empire in the second half of the 19th century prompted the creation of other volunteer and yeomanry units, such as the Volunteer Force, with a far less distinct role, as well as the permanent embodiment of the militia in vulnerable British towns.}}</ref><ref>{{cite journal|title=The British Volunteer System |journal=The North American Review|author=Rt. Hon Earl Brownlow|author-link=Adelbert Brownlow-Cust, 3rd Earl Brownlow|page=745 |date=1 May 1900}}</ref>

The [[Yeomanry|Yeomanry Force]] was made up of mounted units, organised similarly to the Volunteer Force, first raised during the two decades of war with France that followed the French Revolution. As with the Volunteers, members of the Yeomanry were expected to foot much of the cost of their own equipment, including their horses, and the make-up of the units tended to be from more affluent classes.<ref>{{cite web |url=https://www.nam.ac.uk/explore/civilian-soldiers |title=Civilian soldiers |author=<!--Not stated--> |date=<!--Not stated--> |website=National Army Museum |access-date=9 September 2021 |quote=The yeomanry, a mounted force drawn from the upper classes, was created at the peak of the fear of French invasion and used extensively in support of the civil authority to put down riots and disturbances.}}</ref><ref>{{Cite web|url=https://api.parliament.uk/historic-hansard/lords/1903/may/26/an-imperial-yeomanry-reserve|date=26 May 1903|title=An Imperial Yeomanry Reserve  |website=[[Hansard|Parliamentary Debates (Hansard)]]}}</ref>

Although Militia regiments were linked with British Army regiments during the course of the Napoleonic Wars to feed volunteers for service abroad into the regular army, and volunteers from the Reserve Forces served abroad either individually or in contingents, service companies, or battalions in a succession of conflicts from the [[Crimean War]] to the [[Second Boer War]], personnel did not normally move between forces unless re-attested as a member of the new force, and units did not normally move from the Reserve Forces to become part of the Regular Forces, or vice versa. There were exceptions, however, as with the ''New Brunswick Regiment of Fencible Infantry'', raised in 1803, which became the [[104th (New Brunswick) Regiment of Foot]] when it was transferred to the British Army on 13 September 1810.<ref>{{cite book |last1=Grodzinski |first1=John R. |title=The 104th (New Brunswick) Regiment of Foot in the War of 1812 |date=2014 |publisher=Goose Lane Editions |isbn=9780864924476 |language=en}}</ref>

Another type of reserve force was created during the period between the French Revolution and the end of the Napoleonic Wars. Called [[Fencibles]], these were disbanded after the Napoleonic Wars and not raised again, although the [[Royal Malta Fencible Regiment]], later the ''Royal Malta Fencible Artillery'', existed from 1815 until the 1880s when it became the [[Royal Malta Artillery]],<ref>{{cite web |title=Royal Malta Fencible Regiment (1815–1861) |website=Armed Forces of Malta |date=2020 |url=https://afm.gov.mt/en/oldpages/fencibleregiment/Pages/Royal-Malta-Fencible-Regiment.aspx |access-date=9 September 2021 |archive-date=7 May 2019 |archive-url=https://web.archive.org/web/20190507170302/https://afm.gov.mt/en/oldpages/fencibleregiment/Pages/Royal-Malta-Fencible-Regiment.aspx |url-status=dead }}</ref> and the [[Royal New Zealand Fencible Corps]] was formed in 1846.<ref>{{cite book |last=Cowan |first=James |year=1955  |chapter-url=http://nzetc.victoria.ac.nz/tm/scholarly/tei-Cow01NewZ-b1-1-14.html |chapter=The Royal New Zealand Fencibles |title=The New Zealand Wars: A History of the Maori Campaigns and the Pioneering Period |volume=I: 1845–1864 |series=New Zealand Wars (1845–1872) |publisher=R.

The Reserve Forces were raised locally (in Britain, under the control of [[Lord-Lieutenant|Lords-Lieutenant]] of counties, and, in [[British Overseas Territories|British colonies]], under the [[Governor#United Kingdom overseas territories|colonial governors]], and members originally were obliged to serve only within their locality (which, in the United Kingdom, originally meant within the county or other recruitment area, but was extended to anywhere in Britain, though not overseas). They have consequently also been referred to as ''Local Forces''. As they were (and in some cases ''are'') considered separate forces from the British Army, though still within the British military, they have also been known as ''Auxiliary Forces''. The Militia and Volunteer units of a colony were generally considered to be separate forces from the ''Home'' Militia Force and Volunteer Force in the United Kingdom, and from the Militia Forces and Volunteer Forces of other colonies. Where a colony had more than one Militia or Volunteer unit, they would be grouped as a Militia or Volunteer Force for that colony, such as the Jamaica Volunteer Defence Force. Officers of the Reserve Forces could not sit on Courts Martial of regular forces personnel. The [[Mutiny Act]] did not apply to members of the Reserve Forces. The ''Reserve Forces'' within the British Isles were increasingly integrated with the British Army through a succession of reforms (beginning with the [[Cardwell Reforms]]) of the British military forces over the last two decades of the Nineteenth Century and the early years of the Twentieth Century, whereby the Reserve Forces units mostly lost their own identities and became numbered Militia or Volunteer battalions of regular British Army corps or regiments.<ref>{{Cite web|url=https://api.parliament.uk/historic-hansard/commons/1895/mar/15/the-army-estimates|date=15 March 1895|title=The Army Estimates   |website=[[Hansard|Parliamentary Debates (Hansard)]]}}</ref>

In 1908, the Yeomanry and Volunteer Force were merged to create the [[Territorial Force]] (changed to ''Territorial Army'' after the First World War), with terms of service similar to the army and Militia, and the Militia was renamed the ''Special Reserve'',<ref>''HART'S ANNUAL ARMY LIST, SPECIAL RESERVE LIST, AND TERRITORIAL FORCE LIST, FOR 1911: (BEING THE SEVENTY-SECOND ANNUAL VOLUME,) CONTAINING DATES OF COMMISSIONS, AND A SUMMARY OF THE WAR SERVICES OF NEARLY EVERY OFFICER IN THE ARMY, SUPPLY &c.

Although the Territorial Force was nominally still a separate force from the British Army, by the end of the century, at the latest, any unit wholly or partly funded from Army Funds was considered part of the British Army. Outside the United Kingdom-proper, this was generally only the case for those units in the [[Channel Islands]] or the [[Imperial fortress]] colonies ([[Nova Scotia]], before [[Canadian confederation]]; [[Bermuda]]; [[Gibraltar]]; and [[Malta]]).<ref>{{Cite web|url=http://livelb.nationalarchives.gov.uk/first-world-war/a-global-view/the-caribbean/bermuda/|title=The National Archives – Homepage|first=The National|last=Archives|access-date=24 April 2021|archive-date=17 June 2021|archive-url=https://web.archive.org/web/20210617014624/https://livelb.nationalarchives.gov.uk/first-world-war/a-global-view/the-caribbean/bermuda/|url-status=dead}}</ref><ref>''The Quarterly Army List''  Part I, January 1945.
