It's still Russian troops doing it so they will still attack anything belonging to Ukraine. It's not like the put out a Facebook ad for this.

They're trying to incentivize people to take out the new tanks because they're not sure how to deal with them effectively, so they want their troops to do whatever they can to take them out. If they get 12 reports of destroyed tanks and 9 of them were killed in the same, or similar, fashion then they will start telling all their troops to use that method to deal with them.
