Hey Bar, I'd like to add that you don't have to use all of the sounds in a sound pack. I have got most, if not all, the sound packs and mix them up. It takes some time to go though every sound one by one but it's sure worth it when it's all done. I can sit in the tower now and can tell if a 38J or 38L is out there. Whether a Panzer or Sherman, LA5 or 7.
It's a lot of fun to mix it up.
