3 Trucks spawn, drive to a flat area to make a temporary, short airfield and act as a re-arm point for fighters. It's a forward mobile airbase. Very soft forward airfield.
Maybe even later on it can accept downed pilots from returning jeeps/M3s/Grasshoppers - but you can't up new planes from it.
GVs could re-arm and refuel there too - reason to bring back a fuel load on GVs. Supply M3s would shuttle back and forth. etc.
