Ernst, it means lots.
I'm reading every post, don't worry.
I'm actually thinking how to implement this since there are contradictory requests: some wants buildings, some wants flat areas, some wants no airport defense, some do...
I think I'll do the sandbags and a machine gun on each side. But not automatic, you actually have to go and use it yourself.
But there is a problem... airplanes are easy targets for this kind of guns. Once you are in position, no airplane would be able to pass. I'm trying to come up with a solution.
Probably put 2 or 3 guns, but each with limited angle of fire (30 degrees or so), so the airplane can come from behind.
This whole thing would also require that I have a soldier that is able to walk from gun to gun (not easy to animate). Then I have to think how the personal gun should work, how many ammo and power (could they bring down an airplane or tank?) and whether they should be able to reload and get ammo somewhere else.
In short, a request may not be as simple as it looks
