Grenadiers are super strong now. This patch made charging in with infantry very dangerous, while at the same time made soviets only good at short range. Stick your LMG42 grens in some cover and they will only lose to snipers.
Edit: Heck, they don't even need cover. Last night I had a vet 2 LMG42 squad out in the open. They were charged by a vet1 full health shock trooper squad. By the time the shock troopers were in effective range (<5 meters lol), only 2 models were left and they were wiped out on retreat.
Whats wrong with that? A shock squad charges in the open a vet 2 grenadier squad with an LMG. 440mp vs 240mp/60 Munis/Vet 2 - It sounds like you didn't even try and pop off a nade, you didnt pop-off smoke, you didn't use line of sight correctly and then complain because a slightly weaker squad was able to beat your expensive, poorly micro'd, squad.
I think some soviet players need to realise they're going to have to micro harder to get their moneys worth out of their troops, the days of shock troops just obliterating everything regardless of poor micro are gone.
