One of the better counters to soviet snipers is the half track reinforce with g43 greb spam. The extra dps from g43s will wear the soviets down and the reinforce will keep you on the field long enough to cap viable territory.
Other advice is veto really open maps like rails and metal. Axis acutally fair pretty well on close combat styled maps since patch.
This has been working for me atleast, i will admit though majority of OKW players are really bad lol.
G43's is where it's at, just spam that. The sniper build often seens all of his Penals going AT or he hauls out early guards. This gives you superiority in AI with G43's (build like 3-4) also toss a Pgren in there for some lovely nades and high dps.
Though, that doesn't solve how the 222 is suppose to handle a sniper... it's sad to say but Bren carrier can do far more in this game now than a scout car usually can and.. as mentioned cost no fuel.
