I notice that the flag held up by "Men of 1st Battalion 92nd Mech Brigade, making clear..." has what appears to be a traditional Cossack on it. Makes me think of Taras Bulba.

Anyone know the story of this flag? 92nd Mech Brigade only? Whichever army group they're part of - or just the guys in the 1st Battalion looking to tell folks the Cossacks are back! Glad to see 'em BTW.
