In June of 2014, the port city of Mariupol in Donetsk oblast came back under Ukrainian control.
The liberation was due to the highly controversial Azov volunteer battalion, now a special regiment of the ministry of internal affairs.
Azov always has been different to other groups, and even now, as it is an official fighting group, the difference to other armed groups is striking.
Azov had come a long way since its formation, when it is said that all sorts of radicals, hooligans, ultras, right-wing sympathizers came together. Back in the day they were branded Neo-Nazis, and they still are. But are they?
First video on Azov.
