When tanks hit a/c repeatedly, they are using HE rounds. You only have to be close with the shot. I have even downed an a/c by shooting at a tree as the plane
approached. Timing is the key. The round explodes and the plane flies through the explosion. You can kill them with HVAP and AP as well, but the HE rounds by far work the best.
There is no natural camouflage or building for the tanks to hide in without their icon being seen in any terrain. B-25's and IL-2's fly at tree top level looking
for that little red icon. They see the icon, not the GV.
GV's are still going to get bombed, it just won't be so easy.
