Second video: The two cons in the right didn't storm Pzgrens while they were engaged fighting guards. No, why should they do that? They keep distance seeking for a doubtfull yellow cover. PzGrens were fighting with a guard unit and won (of course - cover type + units strengt). What would I have done? Close with my 2 cons squads in hugging distance, even with "ourrah". I can guarantee to you that the ending would have been different.
Now tell me I'm wrong.
Rushing at a panzergrenadier unit in cover with conscripts often ends up with a massacre like in the first video. The conscripts would only have a chance to non-cost effectively force the Pgrens off if they happen to need to reload the moment the cons are on the other side of the cover, or when both conscripts are armed with PPSH41s.
In my opinion the conscript squad on the right should have have stayed behind the wall on the right or move south a little to flank the panzergrenadiers without closing in on them. The other conscript squad should have hidden behind the truck. In that case the lone panzergrenadier unit would be unable to cross the gap to the truck without taking casualties. The only thing they could have done then was to close in on the squad on the right. However, the con squad on the right could then Oorah back and the Panzergrenadiers would have a hard time getting a cost-effective engagement. This however, would be completely fine as the Soviet player would have microd his more expensive force in a correct manner.
