I've always had an easier time with Soviets. It's easier to just point a squad at a sector and check up on them every once in awhile. Not like Ostheer where I could send them off to a sector, look back 10 seconds later and 3 of them are on fire! Soviets are quite nasty with the squad wipes if you don't watch, and sometimes even if you do. But at the same time they're virtually immune to it due to model count and severe lack of Ostheer AI.
Ostheer Tanks can be a challenge to deal with, but proper use of Conscripts, Field Guns, SU-76, and SU-85 make it manageable.
Hmm well. Timing molotovs ain't too easy. If your enemy watches his units you wasted ammunition + cooldown for them without inflicting damage. Same counts for Mortar strikes and other stuff.
On the other hand, I've had multiple games during the last days where I managed to get 2-3 ppsh squad wipes with a single Pgren that I moved through their retreating path. So, both factions have their squad wipe power...
In general it's ridiculous how easy everything dies on retreat. I just love it...
