Thanks a lot, Kornei!
Yes, that sounds like 'Putin's Cossacks' and Rosgvardia.
Re. number of Cossacks: got the number of 600,000 in quite a reputable, published source, thus very much surprised the same would be that much 'off'....?
Perhaps yes, they're all 'drunkards with potbellies', but the ones on photos I've posted today don't look that 'much better' …
