Nothing really surprised me in that video, isn't urban combat defined by extremely high attrition in this war? An average infantry man on both sides are really just drone/artillery targets until they reach the next dugout.
I feel like this thread has a unreasonably rosy view of Russian losses. Even if they have fire superiority, it is exceedingly difficult/expensive to dislodge an enemy from a prepared urban environment.
What's really dumb is going to Russia as PMC when there are a myriad of less hazardous military adjacent gigs that will have similar pay without risking a UAV to the dome.
It depends of what you consider rosy.
Most people don’t think Russian loses are small in absolute terms, they are small in relation to the available pool of men in the Russian army and they are specially very small in relation with the gargantuan ukranian loses.
Probably Russia have lost 100k men or so, more or less is what is possible to extrapolate from weekly numbers of media zona and some weekly estimations I saw time ago.
However it is important to notice that most of Russian loses were either Wagner fighters, either prisioners recruited, either militias of Donbass (that are now 1st and 2nd army corps).
