Show us one replay where vanilla grens out of cover won against vanilla cons/penals in green cover. I call it either BS because you are butthurt or the cons/penals didn`t had the green cover directly in between them and the grens.
maybe it is just to hard to understand for ur butthead.
grens will win against cons or penals at long range if both has green cover. And if u are trying to move out of cover to come near enough using molotovs they will just hit u so hardly that u need to retreat to survive.
theres no way to beat them with just only cons or penals. The only way is using 2 units to beat 1 German unit. Or ppsh spam but this is still commander dependent.
if u need an example just search as soviet and try to fight grens on long range.
