The '''Infantry of the British Army''' comprises 49 [[infantry]] [[battalion]]s, from 19 [[regiment]]s. Of these, 33 battalions are part of the [[Standing army|Regular army]] and the remaining 16 a part of the [[Army Reserve (United Kingdom)|Army Reserve]]. The British Army's Infantry takes on a variety of roles, including armoured, [[Mechanized infantry|mechanised]], [[air assault]] and [[Light infantry|light]].

==Recruitment and training==
{{British Army Arms}}

===Recruitment===
[[File:British Army Infantry Recruiting areas.png|thumb|right|Recruiting areas of British line infantry regiments]]
Traditionally, regiments that form the combat arms of the British Army (cavalry and infantry) recruit from specific areas of the country. Infantry regiments had been assigned specific areas from which they would recruit from by the mid eighteenth century. These were formalised under the [[Cardwell Reforms]] that began in the 1860s. Under this scheme, single battalion infantry regiments were amalgamated into two battalion regiments, then assigned to a depot and associated recruiting area (which would usually correspond to all or part of a county). The recruiting area (usually) would then become part of the regiment's title. It was this that gave rise to the concept of the "county regiment", with the local infantry regiment becoming part of the fabric of its local area.

Over time, regiments have been amalgamated further, which has led to recruiting areas of individual regiments increasing in size. Often, these amalgamations have been between regiments whose recruiting areas border each other. However, there have been occasions where regiments of a similar type, but from widely different areas, have been amalgamated. Two modern examples have been the Royal Regiment of Fusiliers (amalgamated from the county regiments of Northumberland, Warwickshire, [[City of London]] and Lancashire, all of which were regiments of [[fusiliers]]) and The Light Infantry (amalgamated from the county regiments of Cornwall, Somerset, Shropshire, South Yorkshire and Durham, all of which were regiments of [[light infantry]]).

Since September 2007, when the most recent reforms were completed, the infantry has consisted of 18 separate regiments. The five regiments of foot guards recruit from their respective [[home nations]] (with the exception of the Coldstream Guards, which recruits from the counties through which the regiment marched between Coldstream and London). Scotland, Ireland and Wales each have a single regiment of [[line infantry]] from which they recruit (though the battalions of the Royal Regiment of Scotland recruit from the areas they recruited from when they were separate regiments), while England has seven line infantry and rifles regiments. The Parachute Regiment recruits nationally, while the Royal Gurkha Rifles recruits most of its serving personnel from [[Nepal]], and the [[Royal Gibraltar Regiment]] recruits from the [[UK]] and [[Commonwealth nations]]

Before the [[Second World War]], infantry recruits were required to be at least {{convert|5|ft|2|in|m}} tall. They initially enlisted for seven years with the colours and a further five years with the reserve. They trained at their own regimental depot.<ref>[[War Office]], ''His Majesty's Army'', 1938</ref>

===Training===
Unlike the other trades in the army, which have separate units for basic training and specialised training, new recruits into the infantry undergo a single course at the [[Infantry Training Centre (British Army)|Infantry Training Centre Catterick]]. This course, called the "Combat Infantryman's Course" (CIC), lasts 26 weeks as standard and teaches recruits both the basics of soldiering (Phase 1 training) and the specifics of soldiering in the infantry (Phase 2 training). On completion of the CIC, the newly qualified infantry soldier will then be posted to his battalion.<ref>{{cite web|last1=Marshall|first1=Andrew|title=British Army Phase 1: Initial Military Training|url=http://bootcampmilitaryfitnessinstitute.wordpress.com/military-training/armed-forces-of-the-united-kingdom/british-army-phase-1-initial-military-training/|access-date=27 July 2014}}</ref>

For some infantry units, the CIC is longer, due to specific additional requirements for individual regiments:
*The Foot Guards CIC has an additional two-week enhanced drill course.
*The Parachute Regiment CIC has an additional two-week [[P Coy|Pre-Parachute Selection]] (PPS) course.
*The Brigade of Gurkhas CIC combines the Common Military Syllabus with the CIC, together with courses on British culture and the [[English Language]]. The Gurkha CIC lasts 37 weeks.

Officers receive their initial training at the [[Royal Military Academy Sandhurst]], infantry officers then undertake the '''Platoon Commander's Battle Course''', which is run at the [[Infantry Battle School]] at Brecon in Wales. It is here that leadership and tactics are taught to new platoon commanders. New NCOs and Warrant Officers are also sent on courses at Brecon when they come up for promotion. This encompasses Phase 3 training. Phase 3 training is also undertaken at the Support Weapons School at Warminster, where new officers, NCOs and soldiers are trained in the use of support weapons (mortars, anti-tank weapons) and in communications.

Reservist Infantrymen undertake preliminary training at [[Regional training centre|Regional Training Centres]] prior to attending a two-week CIC (Reserve) at Catterick.

===Headquarters Infantry===
Headquarters Infantry, which is located at [[Waterloo Lines]] on Imber Road in [[Warminster]], is responsible for recruiting, manning and training policy of the Infantry.<ref>{{cite web|url=http://www.army.mod.uk/infantry/23300.aspx|title=Headquarters Infantry|publisher=Ministry of Defence|access-date=23 November 2014}}</ref>  Headquarters Infantry was established in 1991 as a result of the Options for Change reform.<ref name=":0">{{Cite web|date=1 September 2008|title=Warminster Garrison: Leisure Time|url=http://www.army.mod.uk/linkedfiles/soldierwelfare/supportagencies/aws/communityguides/sw_sa_aws_cg_warminster_w/warminster_section_4_08.pdf|access-date=16 April 2021|website=British Army|archive-date=9 January 2008|archive-url=http://webarchive.nationalarchives.gov.uk/20080109233241/http://www.army.mod.uk/linkedfiles/soldierwelfare/supportagencies/aws/communityguides/sw_sa_aws_cg_warminster_w/warminster_section_4_08.pdf|url-status=bot: unknown}}</ref>

==Divisions of infantry==
The infantry in the British Army is divided for administrative purposes into divisions. These are not the same as the ready and regenerative divisions (see below), but are based on either the geographical recruiting areas of the regiments, or the type of regiments:
*The [[Guards and Parachute Division]] has the regiments of [[Foot Guards]] plus the [[Parachute Regiment (United Kingdom)|Parachute Regiment]].
*The [[Union Division]] has the infantry regiments from [[Scotland]], [[Wales]] and [[Ireland]], plus one from [[England]].
*The [[Queen's Division]] has the regiments from England, as well as [[Royal Gibraltar Regiment|Gibraltar]].
*The [[Light Division (United Kingdom)|Light Division]] has the two remaining regiments of rifles and Gurkha Rifles.

Each division, in addition to the regiments under its administrative control, also hosts a battalion of [[Ranger Regiment (United Kingdom)|The Rangers]], the newly formed special operations unit.

The four existing divisions were formed as a result of the [[Future Soldier (British Army)|''Future Soldier'']] reforms announced in 2021; prior to this, only the Queen's Division of the new formations existed. The [[Guards Division]], [[Scottish, Welsh and Irish Division]] and [[King's Division]] were the other three formations, while a number of other regiments sat outside the divisional structure.

==Types of infantry==

===Operations===
Within the British Army, there are six main types of infantry:
*'''Armoured Infantry''' – armoured infantry are equipped with the [[Warrior Tracked Armoured Vehicle|Warrior]] [[Infantry Fighting Vehicle]], a tracked vehicle that can deploy over all terrain.
*'''Mechanised Infantry''' – mechanised infantry (or "protected mobility infantry) are equipped with wheeled armoured vehicles for transporting troops. This is divided into "heavy protected mobility infantry" (with large vehicles such as [[Cougar (MRAP)|Mastiff]]), and "light protected mobility infantry" (with smaller vehicles such as [[Ocelot (vehicle)|Foxhound]]).
*'''Light Infantry''' – light infantry are not equipped with armoured vehicles; such units may specialise in jungle and/or arctic warfare
*'''Air Assault Infantry''' – air assault infantry are trained to be deployed using [[helicopter]]s, parachute or aircraft.
*'''Specialised Infantry''' – infantry configured to undertake training, mentoring and assistance to indigenous forces in partner nations.
*'''Public duties''' – infantry on public duties are essentially light infantry units undertaking primarily ceremonial tasks.

===Traditions===
The infantry is traditionally divided into three types:
*'''[[Foot Guards]]''' – foot guards are those infantry regiments that were formed specifically to provide close guard to the monarch. Soldiers in the guards were usually the best trained and equipped members of the infantry. However, they would fight in the same way as ordinary regiments.
*'''[[Line Infantry]]''' – line infantry refers to those regiments that historically fought in linear formations, unlike light troops, who fought in loose order.  The seventeenth and eighteenth centuries saw expansion of the roles of the infantry. To this end, the [[company (military unit)|companies]] stationed on each flank of an infantry battalion were specialist units, with a company of [[light infantry]] trained as skirmishers to operate independently on the battlefield, and a company of [[grenadiers]], who were usually the biggest and strongest men in the battalion, operating as the lead assault troops. In later years, the British Army raised full line infantry regiments classed as light infantry, who operated with muskets alongside specialised regiments armed with rifles.
*'''[[Rifle regiment|Rifles]]''' – in the late eighteenth century, the development of the [[Baker rifle]] led to the commissioning by the British Army of regiments specially trained to use the new weapon. These regiments would operate as skirmishers and [[marksman|sharpshooters]] on the edges of the field of battle. These regiments wore green rather than red tunics to enable them to blend in more with the environment, thus giving them the nickname "green jackets".

The tactical distinctions between infantry regiments disappeared in the late nineteenth century, but remain in tradition. In the order of precedence, the five regiments of foot guards are ranked above the ten regiments of traditional line infantry, who are ranked above the two remaining regiments of rifles.

==Divisions and brigades==
Under the [[Future Soldier (British Army)|Future Soldier]] reforms announced in 2021, the British Army will have a total of 31 regular infantry battalions, 16 reserve infantry battalions and nine independent companies performing a variety of tasks. Under the Future Soldier plan, postings are:

===[[1st (United Kingdom) Division]]===
1st (UK) Division is planned as the UK's primary land element for operations outside the European theatre, as well as operations supporting NATO's flanks. It consists of four infantry centred brigades – one is intended as a high-readiness mobile formation, one as a light infantry formation to provide surge capacity, and one as a parent formation for Army Reserve battalions. The other, 16 Air Assault Brigade, forms part of the overall "Reaction Force", and is a lead element of the UK's [[Joint Rapid Reaction Force|rapid reaction]] strategy. The other major independent element of the Reaction Force is [[United Kingdom Commando Force|UK Commando Force]]; although this does have British Army units attached in combat support roles, the infantry units are from the [[Royal Marines]], which is part of the [[Her Majesty's Naval Service|Naval Service]].{{efn|group=note|The Royal Marines has four battalion-sized units dedicated to the commando infantry role – [[40 Commando]], [[42 Commando]] and [[45 Commando]] are the warfighting elements of 3 Commando Brigade, while [[43 Commando Fleet Protection Group Royal Marines|43 Commando]] is tasked with providing security for the UK's [[Nuclear weapons of the United Kingdom|nuclear deterrent]], as well as supplying marines for maritime security tasks on [[Royal Navy]] ships}}

===[[Field Army Troops]]===
Field Army Troops is the formation encompassing specialist elements of the [[Field Army (United Kingdom)|Field Army]], including signals and [[Intelligence, surveillance, target acquisition, and reconnaissance|ISTAR]] units. The formation has responsibility for two separate infantry brigades, both of which are optimised to a training role - one is primarily intended as a [[Military advisor|mentoring formation]] for the UK's allies, while the other is the Army Special Operations Brigade, which contains those infantry units dedicated to [[Military advisor|military training and operational support for the UK's partner nations]]. The formation also has responsibility for the [[Land Warfare Centre (United Kingdom)|Land Warfare Centre]], an organisation that administers a number of the Army's training centres, which includes one infantry battalion and an additional training company.

===Home Command===
Infantry units are attached to a number of other formations that are independent of the British Army's three existing divisions. London District is responsible for the dedicated public duties units for [[Buckingham Palace|London]] and [[Windsor Castle|Windsor]]. Two company sized units are used at the British Army's training establishments. A number of the United Kingdom's [[British Overseas Territories|Overseas Territories]] maintain their own infantry units, which undertake a number of different roles in addition to internal security.

==History==
===Brigade system, large regiments, disbandings and amalgamations===
Following the end of the [[Second World War]], reductions in the size of the infantry led to the amalgamation of the existing [[regimental depot]]s, together with their operational battalions, into geographically based infantry depots, each designated by a letter of the alphabet from A to O (not including I). In 1948, upon the further reduction of line infantry and rifle regiments to a single battalion, the 14 infantry depots were renamed as geographical brigades (with the exception of Depot J, which was the brigade for those regiments designated as "light infantry", and Depot O, which was for the two regiments of rifles<ref>Whitaker's Almanack 1956, p. 471</ref> ). These brigades assumed the administrative functions from the individual regimental depots, essentially forming what amounted to a multi-battalion regiment. This was taken a stage further following the [[1957 Defence White Paper]], when each brigade adopted a single cap badge that would be worn by all of the regiments under its administration. This led to discussions within the government regarding the flexibility of the infantry under the then present regimental system, as well as the difficulty of potentially making reductions to the size of the army owing to the emotive nature of the amalgamation of regiments into single battalions. This led to the concept of the "[[large regiment]]", which would use the existing brigades as the basis of new, multi-battalion infantry regiments, amalgamating the existing single-battalion regiments en masse, with each of them becoming a battalion of the new formation.<ref>More adaptations forecast in the Army: study of "large regiment" basis for infantry, ''The Times'', 9 March 1962</ref> This process had to a certain degree begun in the [[East Anglian Brigade|East Anglian]] and [[Green Jackets Brigade]]s, which had redesignated the regiments they were responsible for from their old names to numbered designations.<ref>Bigger infantry regiments planned by War Office, ''The Times'', 16 March 1962</ref> These two became the first large regiments as the Royal Anglian Regiment and [[Royal Green Jackets]] in 1964 and 1966 respectively.<ref>First of new large regiments, ''The Times'', 25 February 1964</ref><ref>New Green Jackets Regiment, ''The Times'', 29 May 1965</ref> Four further large regiments (The [[Queen's Regiment]], Royal Regiment of Fusiliers, [[Royal Irish Rangers]] and [[The Light Infantry|Light Infantry]]) were formed between 1966 and 1968, before the process was halted – the brigade system was abolished, with instead all of the remaining infantry regiments grouped into six administrative divisions.

The amalgamations into large regiments coincided with a planned reduction in the size of the infantry – the intention was that the junior battalion of each large regiment or brigade (prior to the implementation of the divisional structure) would be removed, whether by amalgamation or disbanding. This saw plans for the creation of four new single battalion infantry regiments:
*[[Royal Regiment of Wales]] – [[South Wales Borderers]] and [[Welch Regiment]]
*[[Queen's Lancashire Regiment]] – [[Lancashire Regiment]] and [[Loyal Regiment (North Lancashire)]]
*[[Worcestershire and Sherwood Foresters Regiment|Worcestershire and Sherwood Foresters Regiment (29th/45th Foot)]] – [[Worcestershire Regiment]] and [[Sherwood Foresters]]
*Royal Regiment of Gloucestershire and Hampshire – [[Gloucestershire Regiment]] and [[Royal Hampshire Regiment]]

At the same time, three more single battalion regiments elected to disband rather than amalgamate:
*[[The Cameronians|The Cameronians (Scottish Rifles)]]
*[[York and Lancaster Regiment]]
*[[Argyll and Sutherland Highlanders|Argyll and Sutherland Highlanders (Princess Louise's)]]

Three of the regimental amalgamations, two of the regimental disbandments, plus another three of the planned disbandings of large regiment battalions, took place between 1968 and 1970. However, the [[1970 United Kingdom general election|1970 General Election]] saw a change of administration, with the new [[Conservative Party (UK)|Conservative]] [[Heath ministry|government]] electing to review the plans. The outcome of this saw the planned amalgamation of the Gloucestershire Regiment and Royal Hampshire Regiment rescinded, together with plans to disband another four infantry battalions completely. Instead, six battalions were reduced in size to a [[British Army incremental infantry companies|single company]]:

The battalions of the Scots Guards, Royal Hampshire Regiment, Argyll and Sutherland Highlanders, and Royal Green Jackets were subsequently reconstituted.

===Delivering Security in a Changing World (2003)===
{{main|Delivering Security in a Changing World}}
[[HM Treasury]] asked for major cuts in the strength of the infantry in 2003, with at least ten battalions to be disbanded. This proved so unacceptable that, in November 2003, there was consideration to instead reducing each battalion to two rifle companies (with the third to come from the TA).<ref>[https://web.archive.org/web/20031222103150/http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2003/11/24/narmy24.xml News – Telegraph<!-- Bot generated title -->]</ref> By March 2004, ECAB had shown that the maximum number of battalions it was possible to cut was four. This was finally officially announced as part of the army [[Delivering Security in a Changing World|re-organisation]]. The [[arms plot]] system would be abolished; instead, individual battalions would be given fixed roles. To ensure that officers and men could continue to gain the variety of skills that the arms plot provided, the restructuring would also see a series of amalgamations of the remaining single battalion infantry regiments into large regiments. In addition, the regular army will lose four battalions. The roles are divided up as follows:
*Armoured Infantry – 8 battalions (including Land Warfare Training Battalion)
*Mechanised Infantry – 3 battalions
*Light Role Infantry (including public duties and Gurkhas) – 20 battalions
*Air Assault Infantry – 4 battalions
*Commando Infantry – 1 battalion
*Territorial Army Infantry – 14 battalions

The reorganisation was a hybrid of the systems used to organise the regular infantry in [[Australian Army|Australia]] and [[Canadian Army|Canada]]. Australia's regular infantry encompasses eight battalions in a single large regiment, the [[Royal Australian Regiment]] – this system is the one undertaken by the [[Scottish Division]] and the [[Light Division]]. Canada's regular infantry has three regiments, each of three battalions, which is how the [[King's Division]] and the [[Prince of Wales' Division]] will be restructured (albeit with one regiment of three battalions and one of two battalions each).

In addition to the army's infantry battalions, there are three further battalion-sized commando infantry units, which are part of the [[Royal Marines]], as well as eight field squadrons (each larger than an infantry company) of the [[RAF Regiment]], who have responsibility for the ground defence of air assets and are under the control of the [[Royal Air Force]].

The majority of infantry battalions are attached to one of the deployable brigades. However, there are a number of formations that exist to administer those infantry battalions that are not assigned to deployable brigades, but are instead available for independent deployment on [[roulement]] tours.

====Guards Division====
Each battalion in the five single battalion regiments of the Guards Division has a fixed role:
*Armoured Infantry ([[Scots Guards|1 SG]]) – 1
*Light Role/Public Duties ([[Grenadier Guards|1 GREN GDS]], [[Coldstream Guards|1 COLDM GDS]], [[Irish Guards|1 IG]], [[Welsh Guards|1 WG]]) – 4

Two battalions will be assigned as general light role battalions, with the other two assigned to public duties. These battalions will periodically rotate roles and postings.

====Scottish Division====
The six battalions of the Scottish Division have amalgamated into a single five battalion regiment to be called the [[Royal Regiment of Scotland]].
*Armoured Infantry ([[The Highlanders (Seaforth, Gordons and Camerons)|4 SCOTS]]) – 1
*Light Role ([[Royal Scots Borderers|1 SCOTS]], [[Royal Highland Fusiliers|2 SCOTS]], [[Black Watch|3 SCOTS]]) – 3
*Air Assault/Light Role ([[Argyll and Sutherland Highlanders|5 SCOTS]]) – 1

====King's Division====
The six battalions of the King's Division have amalgamated into two regiments;
*[[Duke of Lancaster's Regiment (King's Lancashire and Border)]] – this is a two battalion regiment formed from the amalgamation of the [[King's Own Royal Border Regiment]], [[King's Regiment]] and [[Queen's Lancashire Regiment]].
**Mechanised Infantry (1 LANCS) – 1
**Light Role (2 LANCS) – 1
*[[Yorkshire Regiment]] – this is a three battalion regiment formed from the amalgamation of the [[The Green Howards|Green Howards]], [[Prince of Wales's Own Regiment of Yorkshire]] and [[Duke of Wellington's Regiment]].
**Armoured Infantry ([[Duke of Wellington's Regiment|3 YORKS]]) – 1
**Light Role ([[Prince of Wales's Own Regiment of Yorkshire|1 YORKS]], [[Green Howards|2 YORKS]])- 2

====Prince of Wales's Division====
The original seven battalions of the Prince of Wales's Division have been reduced to five with the transfer of the [[Devonshire and Dorset Regiment]] and the [[Royal Gloucestershire, Berkshire and Wiltshire Regiment]] to the Light Division. The five remaining battalions will amalgamate into two regiments;
*[[Royal Welsh]] – this is a two battalion regiment formed from the amalgamation of the [[Royal Welch Fusiliers]] and the [[Royal Regiment of Wales]].
**Armoured Infantry ([[Royal Regiment of Wales|2 R WELSH]]) – 1
**Light Role ([[Royal Welch Fusiliers|1 R WELSH]]) – 1
*[[Mercian Regiment]] – this is a three battalion regiment formed from the amalgamation of the [[Cheshire Regiment|22nd (Cheshire) Regiment]], [[Worcestershire and Sherwood Foresters|Worcestershire and Sherwood Foresters Regiment]] and [[Staffordshire Regiment]].
**Armoured Infantry ([[Staffordshire Regiment|3 MERCIAN]]) – 1
**Light Role ([[Cheshire Regiment|1 MERCIAN]], [[Worcestershire and Sherwood Foresters|2 MERCIAN]]) – 2

====Queen's Division====
The three existing large regiments of the Queen's Division remain unaffected by the restructuring.
*[[Princess of Wales's Royal Regiment]]
**Armoured Infantry (1 PWRR) – 1
**Light Role (2 PWRR) – 1
*[[Royal Regiment of Fusiliers]]
**Armoured Infantry (1 RRF) – 1
**Light Role (2 RRF) – 1
*[[Royal Anglian Regiment]]
**Mechanised Infantry (1 R ANGLIAN) – 1
**Light Role (2 R ANGLIAN) – 1
*[[Royal Gibraltar Regiment]]
**Light Role (1 RG) – 1

====Light Division====
The four current battalions of the Light Division in two regiments were augmented by two battalions from the Prince of Wales's Division in 2005. These two were amalgamated into a single battalion and then amalgamated with [[The Light Infantry|Light Infantry]] and the [[Royal Green Jackets]] to form a new five battalion regiment, called [[The Rifles]]. On its formation, the Light Division was abolished.<ref>[http://www.army.mod.uk/infantry/regts/the_rifles/rifles_hq/sitrep_2.htm The Rifles – March 2006 situation report 2] {{webarchive|url=https://web.archive.org/web/20060515082627/http://www.army.mod.uk/infantry/regts/the_rifles/rifles_hq/sitrep_2.htm |date=15 May 2006 }}</ref>
*Armoured Infantry (5 RIFLES) – 1
*Light Role (2 RIFLES, 3 RIFLES) – 2
*Mechanised Infantry (4 RIFLES) – 1
*Commando (1 RIFLES) – 1

====Other infantry regiments====

* The single regular battalion of the [[Royal Irish Regiment (1992)|Royal Irish Regiment]] is unamalgamated to "retain an infantry footprint in Northern Ireland".
**Air Assault/Light Role (1 R IRISH) – 1
* The [[Royal Gurkha Rifles]] is unaffected by the restructuring. However, the UK based battalion has been integrated more fully with the rest of the infantry and trained in the air assault role.
**Air Assault/Light Role (2 RGR) – 1
**Light Role (1 RGR) – 1
* One battalion of the [[Parachute Regiment (United Kingdom)|Parachute Regiment]] is the core of the [[Special Forces Support Group|"special forces support battalion"]], no longer part of the Infantry order of battle. The other three operate in the Airborne role.
**Airborne/Light Role (2 PARA, 3 PARA) – 2

====Territorial Army====
With the exception of the Royal Gurkha Rifles, every line infantry regiment has at least one TA battalion (the Royal Regiment of Scotland and The Rifles have two). The Guards Division has The London Regiment as an affiliated TA battalion.

===Strategic Defence and Security Review (2010)/Army 2020===
{{main|Strategic Defence and Security Review 2010|Army 2020}}
Following the [[2010 United Kingdom general election|2010 General Election]], the new government instituted a new defence review. The ultimate conclusion of this process was to reduce the size of the [[British Army]] from approximately 102,000 to approximately 82,000 by 2020. The detail of the process was subsequently announced as ''[[Future of the British Army (Army 2020)|Army 2020]]'' in July 2012. As part of this, the infantry was reduced in size from 36 regular battalions to 31. Of the five to be withdrawn, two were armoured infantry units, two general light infantry and one a specialist air assault infantry battalion. The withdrawal of two armoured infantry battalions is to bring this into line with the planned future operational structure, intended to see three "armoured infantry brigades", each with a pair of infantry battalions, forming the core of the Army's "reaction forces". These two battalions, along with the two light infantry battalions, will be disbanded and their personnel distributed among the remaining battalions of each regiment. The air assault battalion will be reduced to company strength, with the intention that it is assigned as a permanent [[public duties]] unit in Scotland.

The affected regiments were:
*[[Royal Regiment of Scotland]]
**The Argyll and Sutherland Highlanders, 5th Battalion The Royal Regiment of Scotland – Reduced to an incremental company and assigned to [[public duties]] in Scotland.
*[[Royal Regiment of Fusiliers]]
**2nd Battalion, The Royal Regiment of Fusiliers – Disbanded and personnel redistributed to 1st Battalion.
*[[Yorkshire Regiment|Yorkshire Regiment (14th/15th, 19th and 33rd/76th Foot)]]
**2nd Battalion, The Yorkshire Regiment (14th/15th, 19th and 33rd/76th Foot) (Green Howards) – Disbanded and personnel redistributed to 1st and 3rd Battalions. 3 YORKS will eventually be renamed as 1 YORKS. 1 YORKS will eventually be renumbered as 2 YORKS.<ref>[https://web.archive.org/web/20140102194816/http://www.dwr.org.uk/news.php?id=2&nw=239 Duke of Wellington's Regiment]</ref>
*[[Mercian Regiment]]
**3rd Battalion, The Mercian Regiment (Staffords) – Disbanded and personnel redistributed to 1st and 2nd Battalions.
*[[Royal Welsh]]
**2nd Battalion, The Royal Welsh (Royal Regiment of Wales) – Disbanded and personnel redistributed to 1st Battalion.

In addition, the [[Royal Irish Regiment (1992)|Royal Irish Regiment (27th (Inniskilling), 83rd, 87th and Ulster Defence Regiment)]] was transferred to the administration of the [[Prince of Wales' Division]].

===Army 2020 Refine===
Under a further review called [[Future of the British Army (Army 2020 Refine)|Army 2020 Refine]], the 1st Battalion, Scots Guards and the 4th Battalion, The Royal Regiment of Scotland will be equipped with [[Mechanised Infantry Vehicle]]s and form the core of the first Strike Brigade under the Reaction Force. Five infantry battalions will undertake the new specialist infantry role; these units will provide an increased contribution to countering terrorism and building stability overseas, and will number around 300 personnel. Four of these battalions, 1st Battalion, The Royal Regiment of Scotland; 2nd Battalion, The Princess of Wales's Royal Regiment; 2nd Battalion, The Duke of Lancaster's Regiment; and 4th Battalion, The Rifles, will be existing battalions, while the fifth will be formed as a new battalion of the Royal Gurkha Rifles <ref>{{cite web|url=http://www.parliament.uk/business/publications/written-questions-answers-statements/written-statement/Commons/2016-12-15/HCWS367/|title=Strategic Defence and Security Review – Army: Written statement – HCWS367|publisher=Hansard|access-date=16 December 2016}}</ref><ref>{{cite web|url=http://data.parliament.uk/writtenevidence/committeeevidence.svc/evidencedocument/defence-committee/sdsr-2015-and-the-army/oral/34418.html|title=Oral evidence: SDSR 2015 and the Army, HC 108|publisher=Hansard|access-date=17 December 2016}}</ref><ref>{{cite web |url=http://www.janes.com/article/81826/uk-to-recruit-more-gurkha-soldiers |title=UK to recruit more Gurkha soldiers |last=Ripley |first=Tim |date=18 July 2018|website=Jane's 360 |access-date=20 July 2018 }}</ref>

==Other regiments==

===Disbanded regiments===
Over time, a handful of infantry regiments have disappeared from the roll through disbandment rather than amalgamation. In the twentieth century, eight regiments disappeared like this:
*In 1920, the [[Guards Machine Gun Regiment]], a specialist infantry regiment originally formed in 1917, and given the status of a foot guards regiment (ranked as the sixth regiment of foot guards), was disbanded.
*In 1922, following cuts to the size of the armed forces after the [[First World War]] and the establishment of the [[Irish Free State]], the five infantry regiments solely from the south of [[Ireland]] were disbanded:
**[[Royal Irish Regiment (1684-1922)|The Royal Irish Regiment]]
**[[Connaught Rangers|The Connaught Rangers]]
**[[Prince of Wales's Leinster Regiment (Royal Canadians)|The Prince of Wales's Leinster Regiment (Royal Canadians)]]
**[[Royal Munster Fusiliers|The Royal Munster Fusiliers]]
**[[Royal Dublin Fusiliers|The Royal Dublin Fusiliers]]
*In 1968, after a re-organisation of the army, two regiments opted to be placed in suspended animation rather than amalgamate, and were eventually disbanded in 1987:
**[[The Cameronians (Scottish Rifles)]]
**[[York and Lancaster Regiment|The York and Lancaster Regiment]]

===Honourable Artillery Company===

The Honourable Artillery Company included infantry battalions from its formation up to 1973 when its infantry wing was amalgamated with its artillery batteries in a new role.<ref>{{cite book|last=Litchfield|first=Norman E.H.|title=The Territorial Artillery 1908–1988: Their Lineage, Uniforms and Badges|location=Nottingham|publisher=Sherwood Press|year= 1992|isbn=0-9508205-2-0}}</ref>

===Regiments that never were===
Since the Cardwell reforms began, infantry regiments in the British Army have amalgamated on many occasions. However, there have been occasions where amalgamations have been announced, but have then been abandoned:
*'''The Royal Regiment of Gloucestershire and Hampshire''' – planned as the amalgamation of the [[Gloucestershire Regiment]] and the [[Royal Hampshire Regiment]]. This was announced in July 1968 to be implemented in September 1970, but was cancelled in the autumn of that year. The two regiments were subsequently amalgamated with others to form the [[Royal Gloucestershire, Berkshire and Wiltshire Regiment]] and the [[Princess of Wales's Royal Regiment|Princess of Wales's Royal Regiment (Queen's and Royal Hampshires)]]
*'''[[Royal Scots Borderers|The Royal Scots Borderers]]''' – planned as the amalgamation of the [[Royal Scots]] and the [[King's Own Scottish Borderers]] as part of [[Options for Change]]. This was cancelled on 3 February 1993.<ref name=amalgam>{{cite hansard |jurisdiction=United Kingdom |title=Army Manpower |url=https://api.parliament.uk/historic-hansard/commons/1993/feb/03/army-manpower |house=House of Commons |date=3 February 1993 |column=322 |speaker=Malcolm Rifkind |position=Secretary of State for Defence}}</ref> The name was resurrected with the formation of the [[Royal Regiment of Scotland]], when the two regiments amalgamated as a single battalion.
*'''The Cheshire and Staffordshire Regiment''' – planned as the amalgamation of the [[Cheshire Regiment|22nd (Cheshire) Regiment]] and the [[Staffordshire Regiment]] as part of Options for Change. This was cancelled on 3 February 1993.<ref name=amalgam /> The two regiments were subsequently amalgamated as part of the [[Mercian Regiment]].
*The Executive Committee of the Army Board proposed under [[Delivering Security in a Changing World]] that there would be a series of two battalion regiments formed.<ref>[https://www.telegraph.co.uk/news/main.jhtml?xml=/news/2004/07/16/narmy116.xml Hoon wins his regimental campaign]  {{webarchive|url=https://web.archive.org/web/20070325092621/http://www.telegraph.co.uk/news/main.jhtml?xml=%2Fnews%2F2004%2F07%2F16%2Fnarmy116.xml |date=25 March 2007 }} Daily Telegraph 16 July 2004</ref> These may have included:

**A two battalion Highland regiment formed from the Royal Highland Fusiliers, Black Watch, Highlanders, and Argyll and Sutherland Highlanders.
**A two battalion [[Royal Wessex Regiment|Wessex regiment]] formed from the Devonshire and Dorset Regiment and Royal Gloucestershire, Berkshire and Wiltshire Regiment.
*'''Sikh Regiment''' – in 2007, [[Sikh]] leaders in the United Kingdom informed the Army that they would be able to find enough volunteers to form an initial infantry battalion of 700 from within their community. However, the [[Ministry of Defence (United Kingdom)|Ministry of Defence]], having requested advice from the [[Commission for Racial Equality]], decided to reject the proposal on the grounds that it would be "divisive and amounted to segregation".<ref>[https://www.telegraph.co.uk/news/uknews/1555507/Sikh-regiment-dumped-over-racism-fears.html Sikh regiment dumped over 'racism' fears] Daily Telegraph 24 June 2007</ref> In 2015, the idea was revisited, with the Army evaluating the idea. However, [[Michael Fallon|the then Defence Secretary]] stated that he was 'wary of separating military units according to religion'. The idea was again dropped in 2016.<ref>{{cite web |url=https://www.sbs.com.au/yourlanguage/punjabi/en/article/2016/10/05/britain-rules-out-creating-sikh-regiment |title=Britain rules out creating a Sikh regiment |last=Kainth |first=Shamsher |date=5 October 2016 |website=SBS |access-date=25 July 2018 }}</ref> The [[Prince of Wales]] had made a similar suggestion in 2001.
