The Russian AT gun is ridiculous. A tier 1 unit that has the ability to destroy vehicles AND kill any infantry, emplacements, and other AT guns is OP. Might as well put a motor on it and let it run around the field at high speed. A MAXIM with its infinite supply of crew members, a blisteringly fast reorientation speed and NO PACK UP TIME is all you need to support the BEST AT CRAWL IN THE GAME. Add SU-85s to that and its just a joke.
I think think the AT gun is op, the MG is though.
