“blinding” is nothing to shy about. I’m not up to my Russian, but I think it says it’s vulnerable to blinding.

At any rate, if you use a sufficiently explosive shell and destroy a tank’s scopes, it’s basically dead against a fully operational tank, especially if the blind tank relies too much on computer-assisted aiming (which the Leopard does). Blinding first, destroying second is a common tactic in encounters against heavy tanks.
