History

[edit | edit source]

The 4th Tank Brigade was established in late 2017 with the purpose of serving as a reserve unit to the 1st and 17th Tank Brigades within the Ukrainian Armed Forces.[2] It was equipped with T-64 and T-72 tanks.[1] The brigade underwent training and preparation for combat, including a final stage of combat readiness at Honcharivske training base, the home of the 1st Tank Brigade, in July 2018.[3]

During the Russo-Ukrainian War in 2019, the 4th Brigade was sent to the Joint Forces Operation Zone to support the 72nd Mechanized and 36th Marines brigades.[2] The brigade was equipped with T-72 and BMP-2 IFVs, and various artillery pieces.[4] In October of that year, the brigade participated in a joint exercise that involved crossing a river, supported by attack helicopters, and attacking suspected enemy positions.[5]

When Russia invaded Ukraine in February 2022, the 4th Tank Brigade was deployed to help defend the northeastern part of the country.[5] The brigade played a significant role in the battle of Kharkiv and subsequent Eastern Ukraine offensive.[3] It was initially deployed in the area of Sloviansk-Kramatorsk as a reserve unit and later stationed south of Izium.[5] According to Ukrainian military journalist Yurii Butusov (uk), the 4th Tank Brigade took part in the major Ukrainian offensive in the Kharkiv Oblast in September 2022.[6]

On August 1st, 2025, the 4th Tank Brigade was stripped of its third tank battalion in accordance with its conversion to a Heavy Mechanized Brigade. It was the last Ukrainian Ground Forces unit to be thus converted.[7]
