Why use infantry AT weapons?

[Blackcloud6]

I think you have the order of option wrong. I understand all the infantry types roll for the possibility, those who make the roll have the option of using them. They would then get either an AT shot, or could participate in normal assault combat.

No, I don't think so as rule 11.5 (4th Ed.) says: "On each result of 1 through 3 there is no effect and its combat is complete."  That means to me if it fails the roll, it is done and cannot participate further in the assault.


In the Invasion of Germany book it says that the Infantry unit that makes its roll get to do both regular assault and take the AT shot.  But the roll needed to get AT is only 5 or 6.  This rule actually makes more sense consider this is a whole platoon fighting.
