> what do you mean they are "explicitly neo-Nazi"?
Just looks at their crimes at Wikipedia:
> On 11 August, Azov battalion, backed by Ukrainian paratroopers, captured Marinka from pro-Russian rebels and entered the suburbs of Donetsk clashing with Donetsk People's Republic fighters.
They're killing Russians.
> In early September 2014, the Azov battalion was engaged in the Second Battle of Mariupol. Regarding the ceasefire agreed on 5 September, Biletskiy stated: "If it was a tactical move there is nothing wrong with it ... if it's an attempt to reach an agreement concerning Ukrainian soil with separatists then obviously it's a betrayal."
They don't believe Russians.
> As of late March 2015, despite a second ceasefire agreement (Minsk II), the Azov Battalion continued to prepare for war, with the group's leader seeing the ceasefire as "appeasement".
They don't believe Russians.
> In March 2015 Interior Minister Arsen Avakov announced that the Azov Regiment would be among the first units to be trained by United States Army troops in their Operation Fearless Guardian training mission.
They cooperate with US.
> According to Minsk Ceasefire Agreements, foreign fighters are not allowed to serve in Ukraine's military. Despite the Minsk Ceasefire Agreements, the regiment still has foreign fighters, including an ex-British army serviceman Chris Garrett and a 33-year-old former soldier of the Greek army and French Foreign Legion known by the nom-de-guerre of "The Greek".
They allow British and French to kill Russians.
And so on.
