Military
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces. As of 2024, it comprises approximately 74,000 regular personnel and 26,000 reservists, making it one of the largest and most professional armies in the world. Its history spans over 350 years, with roots in the Restoration of 1660, and it has played a central role in global conflicts from the Napoleonic Wars to contemporary counter-insurgency operations.
The British Army traces its formal origins to 1660, when the Restoration of Charles II led to the establishment of a standing force, replacing the ad-hoc armies of the English Civil War. The first permanent regiments, such as the Coldstream Guards, were formed from Royalist and Parliamentary units. Over the following centuries, the army expanded through imperial campaigns, including the Seven Years' War, the American Revolutionary War, and the Napoleonic Wars, where the Duke of Wellington's victories at Salamanca and Waterloo cemented its reputation.
The 19th century saw the Cardwell Reforms (1871) abolish the purchase of commissions and introduce short-service enlistment, professionalizing the officer corps. The 20th century brought two world wars, during which the army grew to over 3 million soldiers in 1918 and 2.9 million in 1945. Post-war decolonization and the end of National Service in 1960 transformed it into a volunteer force, with subsequent operations in Korea, Northern Ireland, the Falklands, Iraq, and Afghanistan shaping its modern character.1
The British Army is organised into divisions, brigades, and regiments, with a command structure headed by the Chief of the General Staff (CGS), who reports to the Chief of the Defence Staff. The army is divided into two main commands: Field Army and Home Command. The Field Army comprises the 1st (UK) Division, 3rd (UK) Division, and 6th (UK) Division, each with specific roles: 3rd Division is the armoured warfighting division, while 6th Division focuses on cyber, information, and special operations.2
Regiments are the historic core, with names like the Royal Tank Regiment, the Parachute Regiment, and the Gurkhas. The Gurkhas, recruited from Nepal, have served since 1815 and are renowned for their bravery and loyalty. The Army Reserve, formerly the Territorial Army, provides additional capability, with units integrated into regular formations. The army also includes the Royal Armoured Corps, Royal Artillery, Royal Engineers, and the Royal Logistic Corps, among others.3
The British Army operates a range of advanced equipment, including the Challenger 2 main battle tank, which is being upgraded to the Challenger 3 standard with a new turret and Rheinmetall 120mm smoothbore gun. The Warrior infantry fighting vehicle is being replaced by the Ajax family of armoured vehicles, though the programme has faced delays and technical issues. The army also fields the AS90 self-propelled gun, the Apache AH-64E attack helicopter, and the new Boxer 8x8 armoured vehicle.4
In recent years, the army has invested in drones, cyber warfare, and electronic warfare capabilities, reflecting the changing nature of conflict. The Future Soldier programme, announced in 2021, aims to modernise the force by 2030, introducing new equipment and restructuring units. The army also maintains a nuclear, biological, and chemical (NBC) defence capability, and its special forces, including the SAS and SBS, are among the world's most elite.5
Soldiers in the British Army enlist for a minimum of four years, with many serving longer. Training is conducted at the Army Training Centre in Pirbright and the Royal Military Academy Sandhurst for officers. The army prides itself on its regimental system, which fosters loyalty and esprit de corps. Ceremonial duties, such as the Changing of the Guard at Buckingham Palace, are performed by regiments like the Foot Guards, and the army's bands are renowned worldwide.6
The army has a diverse workforce, with women serving in all roles since 2018, including combat positions. The Gurkhas, who are Nepalese nationals, have a unique status and are known for their kukri knives and motto 'Better to die than be a coward'. The army also has a strong sporting tradition, with the Army Cup in rugby and the Inter-Services football competition. Welfare and support services, such as the Army Families Federation, assist soldiers and their families.7
Beyond its well-known history, the British Army has several obscure facets. The Royal Army Veterinary Corps has trained animals for warfare, including horses, dogs, and even mules, and in World War I, over 8 million horses died in service. The army also operates the Royal Army Chaplains' Department, which provides spiritual support to soldiers of all faiths. The 'Tank Museum' at Bovington holds the world's largest collection of tanks, including the prototype 'Little Willie'.
The army's role in the British Empire included the use of 'native' regiments, such as the King's African Rifles, which fought in both world wars. The army also had a secretive 'Special Operations Executive' during WWII, which conducted sabotage and espionage behind enemy lines. In 1947, the army carried out the 'Operation Agila' to supervise the partition of India. Today, the army supports civil authorities in emergencies, such as the 2020 COVID-19 response, and maintains a presence in overseas territories like Gibraltar and the Falklands.1
Figures for personnel are approximate and subject to change. The British Army's official name is the 'British Army', though it is sometimes referred to as the 'Regular Army' to distinguish it from the Army Reserve.
