To be honest, for me Soviet Union play to much like combination of America (Infantry in number) and Wehrmacht (Specialized units)...
They lack new gameplay in my opinion. I mean British has mobile HQ while PE has Lock-Down system and dozen of utility vehicle (Ketten, Vampire, and Bergetiger are unique to them)...
Maybe their uniqueness are Command Squad and a lot of 'special' unlocked at veterancy, but those are only realizable by those who familiar with CoH...
So while they fine in current design, they lack something that make them really felt different than vanilla faction.
At least in the eye of newcomer...
Though there are 2 things that I think could be Soviet Union feature: No-Cost ability and Outpost...
Beside that, non.
We feel that coming up with something too radical will drive players away with difference from Relic-like factions. Take a look at the brits. That fucking bus humping faction is a failure design from the start. You can potentially milk up to +42 fuel a minute on one high point.
The soviets are sort of unique in their own way. Units in certain buildings are unlocked as you tech up, and there is no definite unlock pattern that you have to follow. There's tons of viable strategys as well whereas with the other factions there may be 3 or 4 ways to go about skipping tiers strategically. The soviets also heavily support team gameplay in the reasoning that, again, there is no definite teching cycle. One player can invest in close range units, getting Tank Hunters upgraded and unlocking powerful mortars while others can invest in Snipers/Spotters, and powerful AT guns. Same goes for armor too.
Doctrines offer some more flexibility than some of the others with the other factions. When you pick a doctrine like Blitz, for example, what player in his or her right mind would choose the right side of the doctrine first? That's right, the 5% whom don't know how to play. It provides substantially shitty benefits compared to Stormtroopers and Tigers. (StuH is ehhhh.)
The soviets also have some neat little features too. Representing lack of supplies (Conscripts) and teching to higher tier weapons and becoming a late-game powerhouse, which the other two allied factions lack entirely. Most powerful allied tank could be considered Pershing and Firefly (Churchill too?). While armored and/or deadly, they don't present a good, genuine form of elite and deadly armor or infantry that the Axis does, especially with Veterancy, which is purchasable for the Wehrmacht and strategic for the PE. In team matches Axis will come out on top if they manage to drag you out beyond T4 or into Panther Battle Groups/Elite call ins. Soviets can counter that with their Airstrikes, Powerful Arty, their OWN elite call ins, etc.
