Not that I'm against a towed gun, but what I want to see in the GV area is more accurate implementation of sights.
(Then again, maybe it's there and I just don't know how to use it.)
We should be able to dial in a range (say 2500 yards) and the center of your sight is now at 2500 yards, not the bottom of the sight.
(Also, as a side note, the 'zoom' factor on the sights should be made more historic. I don't think they had 40 power zoom on panzer sights in RL.)
Ouch out
