Despite looking great there are a couple of issues with artillery sounds. There are no shell sounds when arty rounds come in. The mortar rounds have a whistle or "woosh" when they land nearby, which sounds appropriate for lighter shells like 60mm. I don't hear anything when the 105s come in. Only dead silence and then the explosion. Realistically there would be a sound far before impact, as the shell travels overhead, however I would expect at least a shriek moments before a large shell lands (as is the case in vanilla). Also regarding the airburst round: there is no sound for the airburst, only the impacts of the shrapnel on the ground. Not sure if these are oversights or bugs but they feel a bit off.
