Are there no DShKs in the game? Seems like a bit of an odd omission if so. Looking at older forum posts, apparently it was removed from the IS-2 for historical reasons, as it was supposedly a post-war addition. However, somebody posted contrary photographic evidence in the same thread, so I'm not sure what's going on there.   In older threads from 2014, there is talk about DShK HMG specialist teams that were supposed to be in the game, but accidentally left out due to an error.
