How do I stop this from happening?

[Ratzki]

I think that because assaulting a tank with AT weapons is abstracted in the game, the closer you are to the tank, the better chances that is what will happen. At the far end of throwing grenades or whatever, the tank activates the squad through the covered arc, but then a series of rolls have to be made to abstractly get a man to run the distance and throw something at the tank. I seem to have much better results when i set the covered arc down to <25m.
