well I think it could even add more of an airfield feeling too, when you take off and see all those parked aircraft on the base, it gives more of an Airfield feeling feeling would be nice to have some life on every base too. I can think of this. not flahing and flashing
not flashing:
Airfield - some people marching (including in town) a few aircraft with some opened parts in the field (like fixing an engine) some fuel trucks moving once in a while.
Vehicle base - cars moving from bunkers to that big hangar, troops marching, empty cars parked arround.
Port - same thing of the vbase basically but the troops would have another skin
flashing
basically scramble feeling so troops actually running, (the alarm already gives a great feeling) couple jeeps running around...
