The following description is exactly as I found with this video.
Funny footage from the Ukrainian TG: the Nazis from "Azov" seized the "Strela" air defense system and threatened to squeeze everything from the Russians. Then they tried to cross the river but got stuck . The Nazis tried to get it with a tractor.

In the end, Russian troops struck at them: the tractors were burned, the Strela was again in the ranks of the RF Armed Forces. happy end
