Who they are

About Unit

4th Heavy Mechanized Brigade is a mechanized unit of Ukrainian Ground Forces formed in 2017 at the  base of 1st Tank Brigade in Honcharivske as 4th Tank Brigade, and part  of the Reserve Corps. The unit was later relocated to the city of  Cherkasy, and subsequently demobilized.

On March 3, 2022, the  brigade was officially reactivated and staffed with mobilized soldiers.  Just two weeks after the Russian full-scale invasion, the brigade was at  full strength and already deployed in combat.

On February 14th,  2023, Poland handed over the first Leopard 2A4 tanks to the brigade. The  unit, upon arrival to Ukraine, became a tank battalion of 33rd Mechanized Brigade.

In July 2025, the tank brigade was reformed into a 4th Heavy Mechanized Brigade.

Insignia

The  central element of the brigade’s insignia is the head of a  silver-armored rhinoceros. This symbolizes unstoppable force,  resilience, and readiness for battle. The black background signifies the  unit’s affiliation with the tank forces.
