# 153rd Mechanized Brigade (Ukraine)

The 153rd Separate Mechanized Brigade (Ukrainian: 153 окрема механізована бригада, romanized: 153 okrema mekhanizovana bryhada), is a formation of the Ukrainian Ground Forces formed in 2023. Five additional mechanized brigades were created in preparation of the Ukrainian counteroffensive in 2024 in response to the 2022 Russian Invasion of Ukraine. The insignia, motto, and creation of the brigade were officially publicized and revealed in December 2023.
Due to a lack of vehicles the brigade was reformed as an infantry brigade in April 2024. On 13 May 2024 the unit returned to the designation as a mechanized brigade, revealing a new unit insignia.

## History
### Formation

The brigade was announced in mid-October 2023, alongside the creation of five new mechanized brigades as part of the Ukrainian Ground Forces, accounting for a five percent expansion of the Ground Forces.
It was reported that the brigade's strength will be filled with 2,000 new recruits. The brigade's purpose was expected to help participate in a Ukrainian counteroffensive in 2024, or possibly against a Russian offensive. According to Forbes, it is unclear where the brigade will receive its equipment that makes them a mechanized brigade; rather than a glorified infantry or motorized brigade. It was noted that the new brigades may not receive new, modern vehicles, but rather old Soviet-era vehicles.
The core of the brigade was reported to me made up of a machine gun platoon, commanded by Nazariy Kishak, belonging to the infamous 72nd Mechanized Brigade. Kishak was known to have been an experienced soldier, participating in the Ukrainian anti-terrorist operation in 2014, commonly referred to as the War in Donbas. The machine gun platoon was created at the beginning of the full-scale Russian invasion of Ukraine, consisting of approximately 200 fighters. Among Kishak's detachment was Oksana Rubaniak, a popular, young female blogger who has been defending Ukraine since the beginning of the full-scale invasion; becoming one of the main faces of the newly established brigade.

### Reforms

The 153rd Separate Mechanized Brigade (Ukrainian: 153 окрема механізована бригада, romanized: 153 okrema mekhanizovana bryhada) became an infantry brigade on 2 April 2024 due to a shortage of vehicles for the newly created brigades, leading to the Ukrainian command to rethink plans. After this, the unit became officially known, until 13 May 2024, as the 153rd Separate Infantry Brigade (Ukrainian: 153 окрема піхотна бригада, romanized: 153 okrema pihotna bryhada).
The designation of the unit as an infantry brigade was lifted on 13 May 2024, when publications by the unit were made revealing that it had returned to the designation as a mechanized brigade. Alongside this, the unit also received a new insignia on 16 May 2024, additionally confirming the designation of the unit as a mechanised brigade.

### Insignia

In December 2023 the brigade revealed its insignia, alongside other core elements of the brigade such as the official publicization of its creation and its motto. The insignia featured a shield with a yellow border, with the interior being blue, reflecting the colours of the Ukrainian flag. In the centre of the insignia was a cross shape, with a variation of the Ukrainian Tryzub symbol towards the top of the insignia. This version of the insignia was retained during the period of the brigade being reformed as an infantry brigade.
After being reformed for a second time, and redesignated as a mechanized brigade, the brigade was seen to have a new insignia on 16 May 2024. The new insignia retained several features such as the colours of the shield, but instead changed the central elements of the insignia. The center of the insignia now featured the head of a boar's head profile in shades of grey.
