The Specialised Infantry Group or (SIG) is a new group of the British Army. The group was formed after the final Army 2020 refines. In addition to providing anti-terrorism training and support allies in overseas areas.[1][2]


The Specialised Infantry Group is the second newest larger formation of the British Army. The group was formed for counter-terrorism training, operations, and specialised training. The group was formed in October of 2017 when the two first battalions joined, being, 4th Battalion, The Rifles (4 RIFLES) and 1st Royal Scots Borderers Battalion, The Royal Regiment of Scotland (1 SCOTS).[1][2][3][4][5]

In February 2018 the group deployed their companies for the first time on operations. Just a few months later in July the group added the 2nd Battalion, The Princess of Wales' Royal Regiment (2PWRR) and also the addition of the Joint Counter Terrorist Training and Advisory Team.[2][3][4][5]

In January of 2019 the group added their fifth unit, 2nd (King's) Battalion, The Duke of Lancaster's Regiment to the group. In April, the 3rd Battalion The Royal Gurkha Rifles joined the group, making a total of 6 units.[2][4][4][5][6][7]

Unlike the other battalions of the British Army the specialised infantry battalions will be a smaller, reduced, stregnth of 267 men compared to the normal 559.[2][8] In 2019, the group joined the 6th (United Kingdom) Division after Force Troops Command was renamed in the beginning of August. In October, all units are expected to have at minimum a company deployed to Spec Inf Operations.


In February 2018 the 4th Battalion, The Rifles (4 RIFLES) deployed for the first time to Kuwait and supported their Kuwait Army and Kuwait National Guard.[9] Just a month before parts of the battalion had deployed to Afghanistan to aid the Afghan National Army in their training.[2][10]

In July 2018 the 2nd Battalion, The Princess of Wales' Royal Regiment had a company, C Company, deploy to Nigeria. The company helped the Nigerian Army in their fight against Boko Haram and against terrorism in the country.[11]


As of 21 December 2019 the group's structure is as follows:[4]
