Choosing to wage war as the Russians or Germans seems to make no difference when you’re executing your strategy; whatever nation you fight seems much better armed and positioned than you. Despite the fact that by mid-1944 the Russians had every advantage - more armor, more troops, fighting one enemy instead of two - you’ll face almost impossible odds when attacking the Nazis (although it works the same when you command the Wehrmacht). Small-caliber cannon will obliterate your powerful tanks while your foot soldiers get chopped to pieces by invisible artillery, causing you to fail repeatedly until luck finally intervenes.
To be sure, the maps, armor, and associated troops all look and sound terrific once the battles have commenced, and there’s an extraordinary range of units available. Missions don’t have a tremendous amount of variety though, as most involve an eventual attack on a centralized location where the enemy is entrenched and pissed the hell off. Overall, there are two major campaigns with sixteen battles, a solid enough amount of content for a $30 stand-alone game built on a mature gameplay engine.
