Ship-born Mi-8 is how.
There’s a ton of propaganda and lies coming from Ukraine and Russia. But not everything is a wag the dog production.
More likely that Russia is incompetent and was goaded into invading Ukraine due to US backchannel intelligence ops. The resulting miserable Russian invasion and US $upport of Ukraine is likely a money laundering scheme.
But, based on video evidence and reports I’ve been able to wade through, this one looks legit.
Would you explain which ship is carrying such a helicopter? The Russian Navy doesn’t have any.
