The British airborne forces, during the Second World War, consisted of the Parachute Regiment, the Glider Pilot Regiment, the airlanding battalions, and from 1944 the Special Air Service Troops. Their formation followed the success of the German airborne operations, during the Battle of France. The British Prime Minister, Winston Churchill, directed the War Office to investigate the possibility of creating a corps of 5,000 parachute troops.

Impressed by the German airborne force during the 1940 Battle of France, the British Prime Minister, Winston Churchill, ordered the creation of a paratrooper force of 5,000 men. The success of Operation Colossus, a small scale commando raid, prompted further expansion of this force, and resulted in an additional requirement for a glider force of 10,000 men to be created. The recruitment for the size of this force took through to 1943, by which time two divisions had been formed. The airborne division was to comprise three brigades: two parachute brigades, each with three battalions from the Parachute Regiment, and an airlanding brigade with three infantry battalions. The first parachute battalions were formed from volunteers from across the British military. As the airborne force grew, infantry battalions were selected to be converted into parachute battalions. The men were invited to volunteer for parachute service, or assigned to a new unit. The new battalions were then brought up to strength from volunteers from other units. The airlanding battalions came from existing infantry units that had been converted into this new role, and the soldiers did not have the ability to opt-out. The latter were flown into battle via gliders, while the former parachuted in.

Neville Chamberlain formed the Chamberlain war ministry in 1939 after declaring war on Germany. Chamberlain led the country for the first eight months of the Second World War, until the Norway Debate in Parliament led Chamberlain to resign and Winston Churchill to form a new ministry.

It was led by Winston Churchill, who was appointed Prime Minister by King George VI following the resignation of Neville Chamberlain in the aftermath of the Norway Debate.

This page is a list of British Corps in World War II. It is intended to provide a central point to access information about British formations of that size.

During the Second World War, the basic tactical formation used by the majority of combatants was the division. It was a self-contained formation that possessed all the required forces for combat, which was supplemented by its own artillery, engineers, communications, and logistical units. On 3 September 1939, at the start of the war, the United Kingdom had two armoured and 24 infantry divisions. In addition, the army had seven anti-aircraft divisions. The anti-aircraft divisions were not comparable in role to formations that were intended to be deployed for combat such as infantry divisions. In September, the British Army stated that 55 divisions would be raised to combat Germany. The United Kingdom would provide 32 of these formations, and the remainder would be raised by the British Dominions and India.

During the Second World War, the brigade was the lowest formation within the military hierarchy, and consisted of multiple battalions, commanded by a brigadier. Generally, three infantry brigades would be used to form an infantry division, although brigades could be used an independent formations. In the latter case, they were usually assigned to a Corps-level command to be utilised. Brigades were flexible formations, and rarely maintained the same subunits. Likewise, brigades could be moved from division to division or corps-level commands, as the tactical or strategic need arose. Their role could also vary dramatically, from being a combat formation to becoming a training organisation. Over the course of the war, 216 uniquely numbered or named brigade formations were formed. However, not all existed at the same time, and several were formed by renaming or renumbering existing formations.

During the Second World War, the British Army maintained and created several mechanised, motorised, and horse-based brigades that were not infantry-based. These mobile forces consisted of battalions and regiments, and were under the command of a brigadier. Brigades could be assigned to a division or operate as an independent formation assigned to a corps headquarters or higher. At the start of the war, in September 1939, the British Army had seven armoured brigades, five tank brigades and one support group. During the war, numerous armoured and tank brigades were raised, renamed, and disbanded. The army also formed eight support groups, three brigades of cavalry, three brigades equipped with armoured cars and two brigades aimed at grouping divisional cavalry regiments.

This is a list of Royal Northumberland Fusiliers battalions in World War II. At the outbreak of the Second World War in September 1939 the Royal Northumberland Fusiliers, a fusilier infantry regiment of the British Army, consisted of seven battalions. A further three were raised during the war. Prior to the war, the regiment was one of a number that been selected to transition from an infantry role to a support role and be equipped with the Vickers machine gun. While most battalions served as divisional machine gun or support battalions, several undertook different roles: motorcycle, searchlight, tank, reconnaissance, regular infantry, and deception units. The regiment saw action with the British Expeditionary Force (BEF) during the Battle of France and Dunkirk, defended the United Kingdom, fought in the North African Campaign, took part in the Battle of Singapore, fought in the Italian Campaign, and operated with the 21st Army Group in the North-West Europe Campaign of 1944–45, operating on the Western Front.
