About Unit

31st Mechanized Brigade is a unit of the Ukrainian Ground Forces.

It was formed in mid to late February 2023, and took part in the summer counteroffensive in southern Ukraine.

Unlike many other newly formed brigades during the Russian full-scale invasion, the unit was equipped primarily with Soviet-era equipment and conducted its training within Ukraine rather than abroad.

As early as February 2023, the brigade’s first mechanized battalion was deployed to the front while the remainder of the formation was still in the process of being organized.

In June 2023, elements of the brigade took part in the assault on Rivnopil in Donetsk Oblast, contributing to the liberation of the settlement.

In July 2025, the 31st Mechanized Brigade was assigned to the 20th Army Corps. Later that month, on July 14, 2025, the brigade was awarded the honorary title named after General-Khorunzhyi Leonid Stupnytskyi.
