The brigade is a unit of theArmed Forces of Ukraine that was formed in 1997 from the 292nd Tank Regiment.[1] In 2014, the brigade was deployed to the border withRussia in theSumy region to protect the route toKyiv.[4] One battalion was also sent to support mechanized brigades in theLuhansk region, mainly around theLuhansk Airport.[5] In 2015, the brigade supported the30th Mechanized Brigade inDebaltseve, where they destroyed at least three enemy tanks.[6]
At the onset of the2022 Russian invasion of Ukraine, the brigade dispersed in anticipation of the imminent bombardment.[7] Following the bombardment, the unit returned toChernihiv to respond to Russian vanguard forces.[5] Russian forces attempted to take the city, but were repelled.[6] However, they eventually bypassed the city, resulting in thesiege of Chernihiv.[8] Despite encirclement, the brigade maintained one supply route for communications and resupply.[6] By 31 March 2022, the brigade had successfully defended the city against Russian attacks and the siege was lifted. Surviving elements of the Russian 41st CAA retreated north toBelarus.[4][failed verification]
The brigade recaptured surrounding Ukrainian towns and the M01 Highway connecting to Kyiv.[9] Following rest and refit in May, elements of the brigade were deployed back to thebattle of Donbas in the area of southernDonetsk andKramatorsk.[10] For its service in Chernihiv, the southern counteroffensive, and the Donbas region, the unit was awarded the recently established honorary award of "For Courage and Bravery" by Ukrainian PresidentVolodymyr Zelenskyy.[11] Zelenskyy also stated that in six months, more than a thousand personnel of this brigade were awarded state awards.[1]
In October 2023, it was reported that elements of the brigade, including its mechanized battalion, were operating near the villages ofNovokalynove andKrasnohorivka (since renamed Yasnohorivka), in theDonetsk Oblast, amida Russian offensive in the area aimed at capturingAvdiivka.[12][13]
In August 2024, after four years as brigade commander, Col. Leonid Khoda resigned from his position, and Lt. Col. Oleh Mohulskyi took his place. In a farewell statement to his soldiers, Khoda said that the brigade had taken part in combat operations atLyman,Lysychansk,Avdiivka,Maryinka,Staromaiorske andRobotyne.[14]
