 The Gotland Brigade was raised as an infantry brigade during the years 1949–1951 under the name, Gotland Brigade (IB 18).This was organized through the Defence Act of 1948, where Gotland Infantry Regiment (I 18) was converted into a brigade.In 1963, when the reorganization into the "Pansarbrigad 63" ("Armoured Brigade 63) was commenced within the Swedish Army, it was decided that Göta Life Guards' (P 1) detachment, the Göta Armoured Life Guards' Company in Gotland (P 1 G), would be amalgamated with the Gotland Infantry Regiment (I 18).
