Structure of the British Army

The structure of the British Army is broadly similar to that of the Royal Navy and Royal Air Force, with a single command based at Andover known as "Army Headquarters". As top-level budget holder, this organisation is responsible for providing forces at operational readiness for employment by the Permanent Joint Headquarters.

The command structure is hierarchical with divisions and brigades controlling groupings of units from an administrative perspective. Major Units are regiment or battalion-sized with minor units being either company sized sub-units or platoons. All units within the service are either Regular (full-time) or Territorial Army (part-time), or a combination with sub-units of each type.

Naming conventions of units differ for traditional British historical reasons, creating a significant opportunity for confusion; an infantry battalion is equivalent to a cavalry regiment. An infantry regiment is an administrative and ceremonial organisation only and may include several battalions. For operational tasks a battle group will be formed around a combat unit, supported by units or sub-units from other areas. Such an example would be a squadron of tanks attached to an armoured infantry battle group, together with a reconnaissance troop, artillery battery and engineering support.

Commands
A command is a military formation that handles a specific task or region, and can direct forces as large as multiple corps or as little as a few battalions.

Under a major army command reorganisation effective 1 November 2011 the Chief of the General Staff took direct command of the Army through a new structure, based at Andover and known as "Army Headquarters".

Reporting to the Chief of the General Staff are: the Commander Land Forces, the Adjutant-General and the Commander Force Development and Training. The Commander Land Forces is responsible for generating and preparing forces for current and contingency operations, the Adjutant-General is responsible for developing the Army's personnel policies and supporting its people and the Commander Force Development and Training is responsible for recruiting and training the Army, and developing its capability, sustainability and doctrine.

The Commander Land Forces commands 1st (Armoured) Division, 3rd (Mechanized) Division and Theatre Troops. He also commands the administrative organisation of garrisons in mainland UK through HQ Support Command based in Aldershot and British Forces Germany.

The Chief of the General Staff is the Standing Joint Commander (UK) (SJC(UK)), responsible for overall command of Military Aid to Civil Power within mainland United Kingdom.

Previously the Army had regional commands in the UK, including Aldershot Command, Eastern Command, Northern Command, Scottish Command, Southern Command and Western Command.

Corps
A corps is a formation of two or more divisions, potentially fifty thousand personnel or more.

Whilst the British Army has the capability there is no standing UK Corps organisation, forces being allocated through a number of multi-partite arrangements to the North Atlantic Treaty Organisation (NATO) and European commitments, providing much of the headquarters capability and framework for the multinational Allied Rapid Reaction Corps.

The word corps is more formally used for administrative groupings by common function, such as the Royal Armoured Corps and Army Air Corps, with various Combat Support Arms and Services being referred to in the wider sense as a Corps, such as the Royal Corps of Signals.

Divisions
A division is a formation of three or four brigades, around twenty thousand personnel, commanded by a Major General.

The British Army has two deployable divisions, capable of deploying the headquarters and subordinate formations immediately to operations.
 * 1st (UK) Armoured Division
 * 3rd (UK) Mechanised Division

London District is responsible for the maintenance of capability for the defence of the capital and the provision of ceremonial units and garrisons for the Crown Estate in London, such as the Tower of London.

Several infantry regiments are organised into five administrative divisions based on the type of infantry unit or traditional recruiting areas:
 * Guards Division
 * King's Division
 * Prince of Wales' Division
 * Queen's Division
 * Scottish Division

Brigades
A brigade contains three or four battalion-sized units, around 5,000 personnel and is commanded by a one star officer, a Brigadier. The brigade will contain a wide range of military disciplines allowing the conduct of a spectrum of military tasks.

The brigade would be required to deploy up to three separate battlegroups, the primary tactical formation employed in British doctrine. The battlegroup is a mixed formation around the core of one unit, an armoured regiment or infantry battalion, with sub-units providing artillery, engineers, logistics, aviation, etc., as required.

Combat formations

 * 1 Mechanised Brigade
 * 4 Mechanised Brigade
 * 7 Armoured Brigade
 * 12 Mechanised Brigade
 * 16 Air Assault Brigade
 * 20 Armoured Brigade

Order of precedence
The British Army parades according to the order of precedence, from right to left, with the unit at the extreme right being highest on the order.

The Household Cavalry has the highest precedence, unless the Royal Horse Artillery parades with its guns.

Combat Arms
The Combat Arms are the "teeth" of the British Army, infantry, armoured and aviation units which engage in close action.

Household Cavalry and Royal Armoured Corps
Regiments of line cavalry and the Royal Tank Regiment together form the Royal Armoured Corps which has units equipped with either main battle tanks or with light armour for formation reconnaissance. An additional reconnaissance regiment is provided by the Household Cavalry Regiment, of the Household Cavalry, which administratively is not considered to be part of the RAC, but is included among the RAC order of battle for operational tasking.

The 1st Royal Tank Regiment operates dual roles, with two squadrons allocated to each:
 * Main battle tank training squadrons within the Combined Arms Training Battlegroup at Land Warfare Centre, Warminster.
 * Divisional augmentation troops attached to 3 Division

Infantry
The Infantry is divided for administrative purposes into five divisions with battalions being trained and equipped to operate in one of five main roles:
 * Air Assault Infantry
 * Armoured Infantry
 * Light Infantry
 * Mechanised Infantry
 * Public Duties

Under the arms-plot system, a battalion would spend between two and six years in one role, before re-training for another. Following a review of the operation of the army it has been demonstrated that the system is inefficient and the system is being phased out, with battalions specialising in role—this will see armoured infantry, mechanised infantry and air assault battalions remaining in a single posting; however, light infantry battalions will continue to be periodically rotated between postings. Personnel will be "trickle posted" between battalions of the same regiment as required, and to further their careers.

Four further infantry units in the regular army are not grouped within the various infantry divisions:
 * 1st Bn, The Royal Irish Regiment (27th (Inniskilling) 83rd and 87th and The Ulster Defence Regiment)
 * 2nd & 3rd Bn, The Parachute Regiment
 * 1st & 2nd Bn, The Royal Gurkha Rifles
 * 1st, 2nd, 3rd, 4th & 5th Bn, The Rifles.

The role of the Royal Gibraltar Regiment is limited to the defence of Gibraltar.

The three senior regiments of foot guards, plus the Royal Regiment of Scotland, each maintain an additional reinforced company that retains custody of the colours of battalions that are in suspended animation:
 * Nijmegen Company, Grenadier Guards (ex 2nd Bn, Grenadier Guards)
 * No. 7 Company, Coldstream Guards (ex 2nd Bn, Coldstream Guards)
 * F Company, Scots Guards (ex 2nd Bn, Scots Guards)
 * Balaklava Company, Argyll & Sutherland Highlanders, The Royal Regiment of Scotland (ex 5th Bn, The Royal Regiment of Scotland)

Brigade of Gurkhas
The Royal Gurkha Rifles is the largest element of the Brigade of Gurkhas which includes its own support arms. These units are affiliated to the equivalent British units, but have their own unique cap badges.
 * Support units of the Brigade of Gurkhas
 * Queen's Gurkha Engineers:
 * 69 Field Squadron, 36 Engineer Regiment, Royal Engineers
 * 70 Field Support Squadron, 36 Engineer Regiment, Royal Engineers
 * Queen's Gurkha Signals:

 * 250 Gurkha Signal Squadron, 30 Signal Regiment, Royal Signals
 * Queen's Own Gurkha Logistic Regiment:
 * 10 The Queen's Own Gurkha Logistic Regiment

Special Forces

 * Special Air Service – The regular army's special forces formation is a single, battalion sized unit, 22nd SAS Regiment.
 * Special Forces Support Group – A tri-service unit formed around 1st Battalion, Parachute Regiment and enhanced with personnel from Combat Support Services, the Royal Marines and RAF Regiment. SFSG is designed to provide support to Special Forces operations.
 * Special Reconnaissance Regiment – A tri-service element of the United Kingdom Special Forces alongside the SAS and Special Boat Service.

Note: UKSF is considered a joint organisation and as such falls outside the Army chain of command.

The Adjutant General's Corps provides administrative, police and disciplinary and educational support to the army. The AGC is an amalgamation with three of the constituent units retaining their previous cap badge. Personnel from the AGC administrative and educational specialisations serve in attached posts to establishments or units of other arms. The police and disciplinary activities retain their own cap badges and act as discrete bodies. The Corps as a whole is divided into four separate branches:
 * Staff and Personnel Branch: The SPS branch is the largest part of the AGC and has responsibility for providing most administrative functions, including finance, IT support, human resources. The SPS branch was formed by the amalgamation of the Royal Army Pay Corps with elements of the Royal Army Ordnance Corps and Women's Royal Army Corps.
 * Education and Training Services Branch: The ETS branch provides for the educational needs of all serving personnel. These cover both professional development within the army, and wider personal development. The ETS branch was formed through the renaming of the Royal Army Educational Corps.
 * Army Legal Services Branch: The ALS branch provides legal advice to the army and to individuals requiring representation at Courts Martial. It is one of the smallest individual units, numbering 120 professionally qualified lawyers. All of its members are officers. The ALS branch retains the cap badge and traditions of the Army Legal Corps.
 * Provost Branch: The Provost branch consists of three separate elements:
 * Military Provost Staff: The MPS is the element of the provost branch responsible for administering military prisons. The MPS is one of the few elements in the army that does not recruit directly; instead, its members are volunteers from other branches of the army. The MPS retains the cap badge and traditions of the Military Provost Staff Corps.
 * Royal Military Police: The RMP provides the army's policing services, both in peacetime and in wartime. Units of the RMP are trained to deploy with the Field Army in the event of mobilisation. The RMP provides two regular regiments and supplements TA regiments with one Provost company each. A further provost company is trained in the air assault mission and is permanently attached to 16 Air Assault Brigade. The Corps also provides a number of specialist capabilities such as the Special Investigation Branch, Close Protection Teams and special escort capabilities.
 * 1 Regiment, Royal Military Police
 * 3 Regiment, Royal Military Police
 * 160 Provost Company – 4 RMP
 * 101 Provost Company – 5 RMP
 * 114 Provost Company – 5 RMP

Other services

 * Royal Army Physical Training Corps
 * Corps of Army Music
 * Royal Army Chaplains' Department
 * Small Arms School Corps

Training
Training in the British Army differs for soldiers and officers but in general takes place in at least two phases:

Phase one training is basic military training for all new recruits. Here candidates learn the basic standards of military performance including operation in the field, weapon handling, personal administration, drill etc. Soldiers in other specialisations undergo the 14 week Army Development Course at one of two Army Training Regiments; Pirbright or Winchester, or the Army Foundation College, Harrogate.
 * Prospective officers attend the Royal Military Academy Sandhurst, where they undergo basic training in soldiering, defence policy and the structure of government, administration, command and leadership. The Commissioning Course for new entry officers lasts 44 weeks. Some specialist branches, Medical and Legal, undergo a short course which provides basic military training.
 * Infantry soldiers undergo a 26 week course at the Infantry Training Centre at Catterick Garrison which combines phase one and phase two training.

Phase two training is specific to the trade which the soldier or officer will follow and is conducted in a branch specialised school. Phase two training enables the individual to join an operational unit prepared to contribute to operational effectiveness. These schools are under the direction of the parent corps or arm of the service, as illustrated above, with the Infantry Training Centre being formed of two training battalions.

Delivering Security in a Changing World
In July 2004 and December 2004 a significant restructuring of the armed forces was announced with a wide ranging impact on all three services. For the army the infantry strength was to be reduced by four infantry battalions (three English and one Scottish) with the remaining single battalion regiments amalgamating within their division; Scottish, King's and Prince of Wales's. The armoured strength was to be rebalanced reducing the strength by seven Challenger 2 squadrons by re-roling one regiment as force reconnaissance. The artillery strength was to be rebalanced, reducing AS-90 battery numbers by six by re-roling a regiment to the light gun and reducing the size of individual Ground Based Air Defence batteries.

The brigade structure was to be restructured to become:
 * One Air Assault Brigade – 16 Air Assault Brigade
 * One Commando Brigade – 3 Commando Brigade. (This is a Royal Naval Commando formation, not part of the Army Chain of Command)
 * One Light Role Brigade – 19 Brigade
 * Three Mechanized Brigades – 1 Mechanised Brigade, 4 Mechanised Brigade and 12 Mechanised Brigade
 * Two Armoured Brigades – 7 Armoured Brigade and 20 Armoured Brigade

Infantry restructuring
The arms plot is to be abolished, with all infantry battalions given a set role and (for armoured and mechanised battalions) location. In order that officers and soldiers can keep up the various skills gained through each of the distinct roles, all single battalion regiments (with the exception of the Guards regiments and the Royal Irish Regiment) will be amalgamated into large regiments. It is planned that each division will have a total of five battalions; of these, one will be armoured infantry, one will be mechanised infantry and the remainder light infantry.

Guards Division

 * Although there will remain five single battalion Guards regiments, operationally these will conform to the new structure, with each battalion being given a specific role (1 armoured infantry, 2 light infantry, 2 public duties). Operationally therefore, the Guards will be a single large regiment. The London Regiment will be transferred to the Guards Division, and become the Guards TA battalion.

Territorial Army

 * With the exception of the Royal Gurkha Rifles, every infantry regiment will receive one Territorial Army battalion, with the exception of the Royal Regiment of Scotland and The Rifles, which will receive two. The Guards Division will gain an affiliated TA battalion.

Bands

 * The British Army has 23 military bands of varying strength. There are seven bands which each have 49 musicians, whereas the other bands each have 35 musicians. All bands can play in many different formats, but primarily as a marching band or a concert band. The Bands of the Household Cavalry also play mounted.

Regular Army

 * 1st Bn, Royal Irish Regiment
 * 1st & 2nd Bn, Royal Gurkha Rifles
 * 2nd & 3rd Bn, Parachute Regiment
 * Royal Gibraltar Regiment

Territorial Army

 * 2nd Bn, The Royal Irish Regiment
 * 4th Bn, Parachute Regiment

Army 2020


In 2010, the incoming government conducted a new defence review. Those elements affecting the army were released as part of the Future British Army Structure (Next Steps publication:. This was subsequently superseded by the Army 2020 concept announced in 2012. Under Army 2020 the army will be divided into:
 * Reaction forces comprising a modified 16 Air Assault Brigade and an armoured division (3rd (UK) Division) of three armoured infantry brigades. These will be the 1st, 12th and 20th Armoured Infantry Brigades.
 * Adaptive forces comprising a division (1st (UK) Division) of seven infantry brigades, three (4th, 7th, and 51st) which will be deployable. This will be assisted by another 2-star command, Support Command (British Army)
 * Force troops and logistics support comprising eight brigades.

Along with three three main elements are a Territorial Army, now designated as the Army Reserve.

All units from Germany will slowly move back to the UK. The basing plan was released on 5 March 2013. This positions 3rd (Mechanised) Division, to be renamed as 3rd (UK) Division as the head of the Reaction Force. 1st (Armoured) Division, to be renamed as 1st (UK) Division, will be the division in charge of the Adaptable Force, being based in York. This basing plan locates all three Reaction Force Brigades, along with the three Armoured Regiments and the six Armoured Infantry Battalions in the Salisbury Plain training area.

The full army structure under Army 2020 until September 2016 is to be:

Reaction Force

 * 3rd (United Kingdom) Division, Bulford
 * Royal Wessex Yeomanry, Bovington (Army Reserve) (MBT Crew Replacement for any of the three Type 56 Regiments below)
