His 10 days does at least refer to a specific event or opportunity- "The next intake of conscripts into the Russian Army is on April 1, when around 130,000 Russian families are required to send their sons (18-25) to Conscription Centers where they will be inducted into the Russian Army as privates."

That being said, the article title does have a bit of clickbait to it (perhaps justified if the goal is to try significantly disrupt this next intake of conscripts.)

Not really; logistics have the finality of gravity about them.

I don't remember hearing that. Who said it?

10 days to flatten Putin.
