3 lets you aim and fire from the flex mounting point. 4 lets you reposition the mount on the ring.
I see what you are talking about with position 3 & 4 on the MG. That makes a big deference thank you for the information that will be a big help. But why not just use the same model as the MK IV panzer? I used to GV almost exclusively but the transmission changes pretty much chased me into planes. Aces High is still brilliant even if I have some complaints. no other on line game even comes close to the game play here.
