A scout car can't but a M5 can. And you shouldn't be able to push 1-2 squads with an M3 either because it makes no sense as a game mechanic, and can entirely negate enemy infantry for very low cost.
Why should a scout car be able to kill pgrens because it can just push them around despite pgrens being a perfect anti-armor counter? Not to mention how easy it is to kill a gren squad before they fire their faust, or after they do.
Here Ill just save you many posts:
I Alexandvar think its perfectly ok for the SWS to push and win early engagements. Negating the value and need for a strong allied early game in certain situations with no real economic risk for OKW while doing so.Unless of course the units that have risk and cost cannot do so either. There!
