1st Armoured Infantry Brigade (United Kingdom)

Initially designated as the 1st (Guards) Brigade, the brigade was part of 1st Division during the First World War. Upon creation of the Guards Division in August 1915, the 1st Battalion, Coldstream Guards and 1st Battalion, Scots Guards moved to 2nd Guards Brigade, and the brigade was redesignated as the 1st Brigade. It was with the 1st Division on the Western Front throughout the war. It saw action at the Battle of Mons and subsequent Great Retreat, the First Battle of the Marne, the First Battle of the Aisne, the First Battle of Ypres, the Battle of Loos, the Battle of Aubers Ridge, the Battle of the Somme, the Battle of Passchendaele, the Battle of Pozières and the Battle of Épehy, part of the final Hundred Days Offensive, which broke the back of the German Army, leading to an Armistice.[3]

The brigade was composed as follows during the war:[4]

• 1st Battalion, Coldstream Guards (until August 1915)
• 1st Battalion, Scots Guards (until August 1915)
• 1st Battalion, Black Watch (Royal Highland Regiment)
• 2nd Battalion, Royal Munster Fusiliers (until August 1914)
• 1st Battalion, Queen's Own Cameron Highlanders (from September 1914)
• 1/14th Battalion, London Regiment (from November 1914, left February 1916)
• 10th (Service) Battalion, Gloucestershire Regiment (from August 1915, disbanded February 1918)
• 8th (Service) Battalion, Royal Berkshire Regiment (from August 1915, left February 1918)
• 1st Machine Gun Company, Machine Gun Corps (formed 26 January 1916, moved to 1st Battalion, Machine Gun Corps 28 February 1918)
• 1st Trench Mortar Battery (formed 27 November 1915)
• 1st Battalion, Loyal Regiment (North Lancashire) (from February 1918)

Remaining active during the interwar period as the 1st (Guards) Brigade, the brigade, still part of the 1st Infantry Division, was sent to France in September 1939 during the Second World War as part of the British Expeditionary Force (BEF) and it later took part in the Battle of France in May–June 1940 and the subsequent Battle of Dunkirk and were evacuated to England, spending the next few years on home defence anticipating a German invasion of England.

HM The King reviews the 2nd Battalion, Coldstream Guards at Bachy, France, December 1939.

On 11 April 1942, the brigade was redesignated and reorganised as 1st Independent Brigade Group (Guards), with its own support units, until August when it was transferred to the 78th Infantry Division. In late 1942, it took part in the North African Campaign in Operation Torch: the Allied landings in French North Africa, arriving in Algiers in November 1942.[3]

The brigade participated in the Run for Tunis and was transferred to the 6th Armoured Division in early 1943 and saw action in the Tunisia Campaign at the Battle of Fondouk, Battle of El Kourzia and Battle of Tunis in April and May 1943. Subsequently, the 1st (Guards) Brigade served on the Italian Front for the rest of the war under command of various divisions, seeing action in the Battle of Monte Cassino (where the brigade played a holding "hinge" role during Operation Diadem) and the Battle of Liri Valley in May 1944.[3] The brigade then fought on the Gothic Line and in the Spring 1945 offensive in Italy.

The 1st (Guards) Brigade was constituted as follows during the war:[5]

• 3rd Battalion, Grenadier Guards
• 2nd Battalion, Coldstream Guards
• 2nd Battalion, Hampshire Regiment (until 1 June 1941, rejoined 10 September 1941 until 25 November 1942, rejoined 18 February 1943, left finally 22 February 1943)
• 1st Infantry Brigade Anti-Tank Company (disbanded 31 December 1940)
• 8th Battalion, Argyll and Sutherland Highlanders (from 25 December 1942 until 16 February 1943)
• 3rd Battalion, Welsh Guards (from 1 March 1943)
• 1st Battalion, Welch Regiment (from 9 March 1945 until 29 June 1945)

Between 11 April 1942 and 7 August 1942 the following units formed the 1st Independent Brigade Group (Guards):[5]

• 8th Battalion, Argyll and Sutherland Highlanders
• 1st Independent Brigade Group Machine Gun Company, 1st Battalion, Royal Northumberland Fusiliers

After the War, the brigade, having lost its 'Guards' title, was transferred to Palestine for internal security duties and then to Egypt for a few months before going back to Palestine in April 1946. Two years later, as the British mandate over Palestine ended, the brigade and division returned to Egypt. In October 1951, British forces pulled out of Egypt outside of the Suez Canal Zone, and later the brigade returned to the United Kingdom, though it was in Cyprus during the EOKA insurgency for a period in 1957–8.[3] In 1968 the dispatch of the entire 3rd Infantry Division began to be planned, as part of the United Kingdom Mobile Force, to reinforce Allied Land Forces Schleswig-Holstein and Jutland (LANDJUT).[6] By the mid-1980s the British Army force earmarked as part of the UKMF to reinforce LANDJUT had shrunk to the 1st Infantry Brigade, as it had become.

In 1991 just before the end of the Cold War, the brigade's structure was as follows.

After the end of the Cold War, the brigade was reassigned to the new 3rd (UK) Division and subsequently became a Mechanised Brigade. In 1996, it was deployed to the Former Republic of Yugoslavia, with Multi-National Division (South-West); in 2000, it was deployed to Sierra Leone and, in 2002, to Kosovo.[3]

The brigade was deployed to Afghanistan as part of Operation Herrick XVIII.[8] It was deployed again in 2014, commanded by Brigadier Rupert Jones.[9]

Under Army 2020, it was renamed as 1st Armoured Infantry Brigade and remained at Tidworth Camp, forming part of the Reaction Force as part of the 3rd (UK) Division.[10][11][12] Under the programme the Brigade consisted of the following units:

Under the Army 2020 Refine programme, the 1st Armoured Infantry Brigade was due to form up as the first of two Strike Brigades by 2021.[16][17][18] The Brigade then consisted of the following units:[19]

• 1st Armoured Infantry Brigade, at Delhi Barracks, Tidworth Garrison (to become 1st Strike Brigade in 2021).[20]
  • Strike Experimentation Group, at Battlesbury Barracks, Warminster Garrison (a developmental command, overseen by HQ 1st AI Bde)[21][22][23][24][25][26]

On 1 July under the Future Soldier programme, the brigade merged with 1st Artillery Brigade to form 1st Deep Recce Strike Brigade Combat Team.[1]

Jane's reported that the brigade was disbanded in early July 2022. The Household Cavalry and Royal Lances were transferred to the 1st Deep Reconnaissance Strike Brigade, and three of the brigade's infantry battalions and the small support subunits were reassigned "to other brigades."[41]
