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.

On a regular basis, Brigade and Battlegroup showcase their skills to act together as a highly responsive and interoperable force during IRON WOLF, the country's largest military exercise involving Allied and Lithuanian troops. It is held every year and aims to improve planning and defence capabilities as well as to increase multinational collaboration across military operations. Equally so, it is bound to improve the mobility of formations and the ability of eFP Battlegroup and Iron Wolf Mechanized Infantry Brigade to rapidly deploy as one unit to conduct operations in defence of Lithuania's and NATO's territory.
