I've noticed that if I'm in an LVTA (with the Howitzer) sitting next to a Panzer, if I fire a shot, I get the LVTA gun sound and if the other person fires, I get the LVT firing sound from his tank. This has also happened with me in a Tiger and a squaddie sitting next to me in a Panzer. I was using Mitsu 2.01 when this ocurred and have downloaded 2.02 now. If I find something different on this topic, I'll post a reply.
