The Scots Guards is ranked as the third regiment in the Guards Division; as such, Scots Guardsmen can be recognised by having the buttons on their tunics spaced in threes. The regiment consists of a single operational battalion, which has been based in Catterick since 2008, in the armoured infantry role. However, since 1993, the regiment has also maintained an independent company, F Company, permanently based in Wellington Barracks, London on public duties. It is the custodian of the colours and traditions of the 2nd Battalion, which was placed in permanent suspended animation in 1993 as a result of Options for Change. 1st Battalion will be equipped with Mastiff Vehicles under Army 2020 and be under 12th Armoured Infantry Brigade.
