The history of Lithuania's Mechanized Infantry Brigade Iron Wolf dates back to 1990. The formations which later became the Brigade sub-units protected the Parliament of the Republic of Lithuania, the Media House, the building of the Ministers' Council, the Vilnius TV tower and other key state establishments against the Soviet Army on the memorable 13 January 1991. The Brigade has been functioning under its current name—i.e. Mechanized Infantry—since 2011, and the wolf in the formation's very name is by no means a coincident.
Legend has it that Lithuania's medieval Grand Duke Gediminas once fell asleep in a valley near the country's present-day capital and had a strange dream—a huge wolf in iron armour was standing and howling on a high hill at the mouth of the Vilnia River. The next morning, Gediminas ordered to bring someone who could interpret this vision. A pagan priest explained the wolf symbolized a town and a castle the Grand Duke would establish that would be as unassailable as the wolf in iron armour. The beast's loud howl was the voice of future heroes whose great deeds would make this town renowned throughout the world. Gediminas obeyed the prophecy. Soon a castle built on the stated place, and they called the town Vilnius. For the Brigade, one of Lithuania's most famous legends stands as a symbol, an embodiment of values, and a guide.
The wolf is associated with attributes the Brigade's soldiers, non-commissioned officers and officers alike, should seek to develop, amongst which are willpower, initiative and loyalty. Together with Mechanized Infantry Brigade Samogitia, the Iron Wolf forms the prime land fighting force in Lithuania.
