Oh god, the 4 models vs 6 models discussion again. An Ostheer squad generally does 1.5 times the DPS of its Soviet counterpart because of the difference in squad sizes. 4 men Ost squads don't die faster than 6 men Soviet squads.
You'd only have a point with AoE damage, if it weren't for the fact that models in Soviet squads seem to be so busy hugging eachother that even a rifle nade can be enough to wipe those squads
(Correct me if I'm wrong, I just started playing again after a break of 6 months, but I'm pretty sure that everything I said was right at that time, and I doubt Relic changed that)
