Yes, I am afraid it is too powerful. No one will be able to attack fields in a tank while ords are up. I will teach everyone the trick right now to level the playing field and get this experiment over with. The following is a simplified reenactment. Up an A-20 and fly along the edge of a dar quadrant. When the quadrant flips, turn 90 degrees toward the quadrant and follow the edge. When it flips, drop bombs, the tank is dead.
I just used this technique to isolate a single tree, before even looking for the tank. Using quadrant flipping, I already knew which tree to scan, so the whole idea of using trees for cover that they were supposedly created and perfected to provide, is now out the window and I retract my impetuous endorsement. I'd foolishly assumed it only worked for gv's where it belongs.
