Please change the gun manning color codes to avoid the present confusion of thinking Red positions are destroyed instead of occupied, and having to keep clicking on Yellow positions to find ones that are not destroyed.
A logical fix would be as follows:
Yellow: Gun is available.
Green: Gun is occupied.
Red: Gun is destroyed.
No need to have an exclusive color for the gun you are trying to occupy -- you know what gun it is since you are clicking on it, and you can see when it turns Green you are the one occupying it.
This can save lots of time trying to quickly find intact and unoccupied guns when bases are under attack. At present, frustrating to have to keep hunting among Yellow positions only to find the message Gun is Destroyed.
Incidentally, what is that strange little black symbol that appears on some gun position dots and not others? What does it symbolize and what does it mean? I realize I'll be told something everyone else knows, but I still need to know.
