Hi SukhoiLover
I don't believe the TOR M1 is combat proven somebody correct me if I'm wrong on but I couldn't find anything. The system is mid to short range so I it can be targeted by aircraft using standoff weapons. Alone it's mainly effective in close but if used correctly in a layered setup with mid and long range SAM's then at least on paper looks deadly. I think it's best used as a "part" of a SAM network and not how Iran is using it because it has limitations.
I don't think you'll get country's military saying in the open yes we know how to jammed it and take it out. It's mobile so as a target it's harder to hit and see but most SAM's as history has proven can be taken out. As crazy as it sound air power is needed to protect a SAM network or at least the outside edges and gaps. From what was explained to me from the edges you can get under and around to take shots.
