I think that would be cool and its a good Idea. Fresh ideas

Hope we can have that some day.
For now what about Something we can implement soon: I'm working on a terrain
It will have several different "attackable" "bombable" objects placed thoughout the map..
Ie. ships, tanks, Artilley,Villages, ect. that can be used as targets.
All my future terrains will be tooled like this..
This way if a set up designer wants to revolve a set up around for instance attacking a tank column they can.
Simply list it in the brief: EXP.
Axis: attack tank columns in grid 9,9 x 7 Allies defend tanks In grid 9,9x7 Along with any other targets they decide to use.
That is just a fast watered down example.
Folks can work toward objectives if they wish as an attack defend type thing 24/7 automatically W/O any intervention.
This way the players can do many things at once in the arena if they choose they can have a squad match and utilize the targets as an objectives. Or the population as a whole can play the set up as attack defend with the included targets by following the orders/script in the brief .
Or the players can just furball if they choose to not participate in a mission.
That way there is a smoother and uniterupted flow to the arena,without somebody "on duty" so to speak to constantly man the helm.
Kind of 24/7 FSO concept but by choice not mandatory..
