The Russian boats are nice for multiplayer because they have the missile torpedoes to quickly rain down hell on your enemies

Assuming you can detect your enemies first haha other than that, you can always just snapshot on the TIW bearing

Other than that, their sonar and, therefore, TMA is a lot trickier because of the lack of waterfall. Not impossible, but definitely trickier.
Seawolf is a lot of fun but it's easy to get rusty on your TMA skills with that nifty WAA
