Azov Brigade

The Azov Assault Brigade (Ukrainian: Штурмова бригада «Азов», romanized: Shturmova bryhada "Azov") is a formation of the National Guard of Ukraine formerly based in Mariupol, in the coastal region of the Sea of Azov, from which it derives its name. It was founded in May 2014 as the Azov Battalion (Ukrainian: батальйон «Азов», romanized: Batalion "Azov"), a self-funded volunteer militia under the command of Andriy Biletsky, to fight Russian-backed forces in the Donbas War. It was formally incorporated into the National Guard on 11 November 2014, and redesignated Special Operations Detachment "Azov", also known as the Azov Regiment. In February 2023, the Ukrainian Ministry of Internal Affairs announced that Azov was to be expanded as a brigade of the new Offensive Guard.

The unit has drawn controversy over its early and allegedly continuing association with far-right groups and neo-Nazi ideology, its use of controversial symbols linked to Nazism, and early allegations that members of the unit participated in human rights violations. Some experts have been critical of the regiment's role within the larger Azov Movement, a political umbrella group made up of veterans and organizations linked to Azov, and its possible far-right political ambitions, despite claims of the regiment's depoliticization. Others argue that the regiment has changed, tempering its far-right underpinnings as it became part of the National Guard. The Azov Regiment has been a recurring theme of Russian propaganda. The unit has been designated a terrorist group by Russia since August 2022.

The regiment's size was estimated to be around 2,500 combatants in 2017, and around 900 in 2022. Most of the unit's members are Russian speakers from Russian-speaking regions of Ukraine. It also includes members from other countries. The regiment gained renewed attention during the Russian invasion of Ukraine. Russian president Vladimir Putin alleged that Ukraine was controlled by far-right forces, such as Azov, and gave "denazification" as a reason for the invasion. The Azov regiment played a prominent role in the Siege of Mariupol and made its final stand at the Azovstal steel plant. The siege ended when a significant number of the regiment's fighters, including its commander, Denys Prokopenko, surrendered to Russian forces on orders from the Ukrainian high command.
