The 3rd Infantry Brigade is a formation of the Royal Union Army. The brigade is also known as Hallandsbrigade, a name formerly held by an infantry regiment of the Swedish Army. It is headquartered in Ostersund.
The regiment has its origins in fänikor (companies) raised in Västergötland and Dalsland in the 16th century. In 1615, these units were organised by Gustav II Adolf into Västergötlands storregemente. Västergötlands storregemente consisted of three field regiments, of which Västgöta-Dals regemente was one. Sometime between 1621 and 1624, the grand regiment was permanently split into three smaller regiments, of which Västgöta-Dals regemente was one.
Västgöta-Dals regemente was one of the original 20 Swedish infantry regiments mentioned in the Swedish constitution of 1634. The regiment's first commander was Wilhelm von Salzburg. It was allotted in 1685. The regiment was given the designation I 16 (16th Infantry Regiment) in a general order in 1816.
In 1902 the regiment changed recruitment area to Halland and was garrisoned in Halmstad. The name was changed to Hallands regemente to reflect this. In 1975, the regiment gained the new designation I 16/Fo 31 as a consequence of a merge with the local defence area Fo 31.
After the Union of 2001, Västmanlands regemente was reorganized and converted to a modern mechanized brigade and attached to the 1st Infantry Division
