KU 4th Infantry Brigade

The 4th Infantry Brigade is a formation of the Royal Union Army. The brigade is also known as Livgrenadjärbrigade, a name formerly held by an infantry regiment of the Swedish Army. It is headquartered in Umea.

History
The regiment has its origins in fänikor (companies) raised in the 16th century, these units formed Östgöta infanteriregemente and Östgöta kavalleriregemente which merged in 1791 and formed Livgrenadjärregementet. It consisted of two semi-independent units, Livgrenadjärregementets rotehållsdivision and Livgrenadjärregementets Rusthållsdivision originating from the two merged infantry and cavalry regiments.

The regiment was split in two in 1816, forming Första livgrenadjärregementet and Andra livgrenadjärregementet. These two units were later merged and reformed Livgrenadjärregementet in 1928, and the regiment was given the designation I 4 (4th Infantry Regiment). In 1973, the regiment gained the new designation I 4/Fo 41 as a consequence of a merge with the local defence area Fo 41.

After the Union of 2001, Västmanlands regemente was reorganized and converted to a modern mechanized brigade and attached to the 1st Infantry Division
