C14 (Січ, occasionally translated as S14) is a far-right political group and street mob formed as a youth wing of the Svoboda party, it was led by Yevhen Karas.

The group was recognised by US authorities as hate group and has acted as a street gang offering their services for money, the group has also been contracted by some government authorities to provide an unofficial police role, forming an organisation known as the “Municipal Guard” to do so:

The administration of at least one district in Kyiv is known to have signed a memorandum of cooperation with the police and a civic organization («Муніципальна варта») which is headed by a member of C14.

Since the beginning of 2018, C14 and other far-right groups such as the Azov-affiliated National Militia, Right Sector, Karpatska Sich, and others have attacked Roma groups several times, as well as anti-fascist demonstrations, city council meetings, an event hosted by Amnesty International, art exhibitions, LGBT events, and environmental activists. On March 8, violent groups launched attacks against International Women’s Day marchers in cities across Ukraine. In only a few of these cases did police do anything to prevent the attacks, and in some they even arrested peaceful demonstrators rather than the actual perpetrators.

To be clear, far-right parties like Svoboda perform poorly in Ukraine’s polls and elections, and Ukrainians evince no desire to be ruled by them. But this argument is a bit of “red herring.” It’s not extremists’ electoral prospects that should concern Ukraine’s friends, but rather the state’s unwillingness or inability to confront violent groups and end their impunity. Whether this is due to a continuing sense of indebtedness to some of these groups for fighting the Russians or fear they might turn on the state itself, it’s a real problem and we do no service to Ukraine by sweeping it under the rug.

The organisation coordinated with the Congress of Ukrainian Nationalists, Organisation of Ukrainian Nationalists, Svoboda and Right Sector during the 2019 Ukrainian elections, endorsing a joint candidate (Svoboda’s Ruslan Koshulinsky - https://www.pravda.com.ua/news/2018/11/19/7198643/), it has also coordinated demonstrations with Tradition and Order, Monolith and the Katekhon movement:

On May 17 activists of Ukrainian right-wing radical groups, such as “C14”, “Tradition and Order”, “Right Sector”, “Monolit”, and “Katekhon”, held the action “Nationalists against the leftists from Amnesty”.
