I played a little bit of the beta
It's German Wermacht vs. Russian Conscript forces. For anyone familiar with the FIRST game, wermacht plays almost exactly the same and it's fucking beautiful. Their squads are small, and elite. Russia has lots of super cheap units with lots of abilities. They get molotovs and anti-tank grenades pretty much right off the bat, because duh conscripts.
Most games are decided by the territory defined by the early moments in the game. At that point Russia pretty much only has squads of 6 shitty-ass conscripts, while the wermacht rolls in with squads of 4 grenadiers from the first unit production building. Conscripts are so shitty, that they even come with an ability to get them to mash their squads together, add them to other squads to command big weapons and such. they're pretty damn cool.
Russian tanks are smaller and shittier than pretty much all german ones, since the Panzer IV is their first tank and you can roll out a tiger by the end of a match. T-34 is nice, but you need 2 or 3 of them to directly fight even one german tank. Like original COH, flanking is incredibly important if you want to destroy a tank first. Which is to say, it's fun.
