Russian version of SWAT (called OMON) use urban camo or black bdu. Friend of mine, who lives in Moscow and serves in OMON sent me bunch of videos about them. Urban and black are the only two kinds of camo I've seen in those videos. Even on tours in Chechnya.
If you want to get something else, just in case you will get to play outdoor, look into spetsnaz GRU. Those guys wear woodland camo. Can't help you with what exactly they are supposed to wear though. I don't think anybody has an answer to that question
because they wear whatever they can get.
Check this link for some pics of cops in action. It's not work safe. There are two pics of a guy with a wound to the head.

Guys wearing urban are OBOB (anti organized crime unit) as far as I can understand but OMON wears similar camo.
