The Infantry of the British Army comprises 49 infantry battalions, from 19 regiments. Of these, 33 battalions are part of the Regular army and the remaining 16 a part of the Army Reserve. The British Army's Infantry takes on a variety of roles, including armoured, mechanised, air assault and light.
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 5inchesft2inchesin (ftin) 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.[1]
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 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.[2]
For some infantry units, the CIC is longer, due to specific additional requirements for individual regiments:
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 Centres prior to attending a two-week CIC (Reserve) at Catterick.
Headquarters Infantry, which is located at Waterloo Lines on Imber Road in Warminster, is responsible for recruiting, manning and training policy of the Infantry.[3] Headquarters Infantry was established in 1991 as a result of the Options for Change reform.[4]
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:
Each division, in addition to the regiments under its administrative control, also hosts a battalion of The Rangers, the newly formed special operations unit.
The four existing divisions were formed as a result of the 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.

Within the British Army, there are six main types of infantry:
The infantry is traditionally divided into three types:
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.
Under the 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 (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 five infantry centered brigades – one is intended as a high-readiness mobile formation, one as a light infantry formation to provide surge capacity, one as a training and mentoring formation for the UK's allies, 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 rapid reaction strategy. The other major independent element of the Reaction Force is 3 Commando Brigade; 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 Naval Service.
3rd (UK) Division is planned as the UK's main reaction force, intended to act as a lead formation alongside NATO, and primarily consists of a pair of armoured brigades containing the army's mechanised infantry units.
6th (UK) Division is the formation encompassing specialist elements of the Field Army, including signals and ISTAR units, as well as the Army Special Operations Brigade, which contains those infantry units dedicated to military training and operational support for the UK's partner nations.
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 London and Windsor. Three company sized units are used at the British Army's training establishments. A number of the United Kingdom's Overseas Territories maintain their own infantry units, which undertake a number of different roles in addition to internal security.
Following the end of the Second World War, reductions in the size of the infantry led to the amalgamation of the existing regimental depots, 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[5]). 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.[6] This process had to a certain degree begun in the East Anglian and Green Jackets Brigades, which had redesignated the regiments they were responsible for from their old names to numbered designations.[7] These two became the first large regiments as the Royal Anglian Regiment and Royal Green Jackets in 1964 and 1966 respectively.[8] [9] Four further large regiments (The Queen's Regiment, Royal Regiment of Fusiliers, Royal Irish Rangers and 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:
At the same time, three more single battalion regiments elected to disband rather than amalgamate:
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 General Election saw a change of administration, with the new Conservative 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 single company:
The battalions of the Scots Guards, Royal Hampshire Regiment, Argyll and Sutherland Highlanders, and Royal Green Jackets were subsequently reconstituted.
See main article: 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).[16] 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 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:
The reorganisation was a hybrid of the systems used to organise the regular infantry in Australia and 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.
Each battalion in the five single battalion regiments of the Guards Division has a fixed role:
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.
The six battalions of the Scottish Division have amalgamated into a single five battalion regiment to be called the Royal Regiment of Scotland.
The six battalions of the King's Division have amalgamated into two regiments;
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;
The three existing large regiments of the Queen's Division remain unaffected by the restructuring.
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 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.[17]
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.
See main article: Strategic Defence and Security Review 2010 and Army 2020. Following the 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 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:
In addition, the Royal Irish Regiment (27th (Inniskilling), 83rd, 87th and Ulster Defence Regiment) was transferred to the administration of the Prince of Wales' Division.
Under a further review called Army 2020 Refine, the 1st Battalion, Scots Guards and the 4th Battalion, The Royal Regiment of Scotland will be equipped with Mechanised Infantry Vehicles 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 [19] [20] [21]
All five battalions will periodically rotate roles
These are the battalions represented by the four incremental companies
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:
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.[22]
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:
