The Azov Battalion, known to be mainly made up of white supremacist militiamen.
They were under siege for a good 3 months in Mariupol while fighting Russia’s elitest Chechnyan’s.
Will Putin send Ramzan Kadyrov back into Ukraine to attack the Azov Battalion in Kiev? I would say, most likely they will continue to rain down missiles on Kiev for as long as they need to prepare for a total takeover of the capitol. So, that battle may come with the neo-Nazi’s in Azov again, but not anytime soon.
