The tank shown in the field has a broken track, left track is incomplete just below the front idler wheel. Watch at 2.21 and you can see the end of the track in front of the first road wheel. Author of this vid has no real idea what he speaks of. Disregard everything except what you can see. I wouldn't take a poke at a main battle tank with ANY RPG. Best I would expect was what happened, a broken track. I doubt there are any secrets unknown about the Leopards.
