No, it's your ridiculous belief that GV's should be immune to air attack which has brought us here.
For some weeks POTW has been finding and killing Cybro and PTBop for parking in the bushes just to create a flashing base or a GVDAR block to act as passive resistance greifing. They end up requiring up to an hour to find them or minutes with a film. Even Virgil has gotten in on the fun...

Their activities have no real effect on local outcomes and can be ignored. The GVers who want to fight after they spawn in, yes they hide but, they eventually give themselves away becasue they came to that location to attack things. Turn off post lighting, GVs really cannot hide at that point. Even parked inside those 5 trees in a ring standard for the Euro and Pac tile sets. With it off, from a storch 100ft above, just look straight down into the trees and you can see them. It's finding that needle in the haystack ring of trees in the 3x3 GVDAR block which is the real problem. Not really different than real life and our GVers now run a few MG rounds into the trees like using sonar looking for hit sprites.
I'll venture about half of our player base drives GV's. And a good number of those fly planes. Our game today in the MA is a combined arms game. GV's once spotted, are doomed becasue of bombs. If they want to sneak around, let them. Once they reveal themselves, they know a timer has kicked in most times that will not end well for them. At least they are showing some stones and taking a risk. We have too much risk avoidance these days.
