Having seen a request regarding manned guns I have to put this on the wish list.  
Add Manned guns to town along the ridge of the hills surrounding the town.
For example:
x4 AT
x4 37mm
No need for 88s in town.
Quantities don't really matter to me.  I just want to start a conversation on this and see how people would feel about this?  It would add a new element to the game.  Defense of town would be easier, however, if the attackers do their job correctly, it won't be a factor.
Thoughts?
