icons are already hidden if you are actually under cover.
I anti-gv in the IL2 with 37mm. I kill engine to hear them running if I dont spot the motion from way out, or haven't spotted them from tower F5 view. Usually, the 1.5k icon is not even visible until well on the attack pass. To kill, if it's an M4, make sure you're patient enough to climb high enough to be able to get steep enough angle to avoid main gun. You will only get main gunned if you're impatient and/or greedy. Avoid all wirbs/osties. panzers and panthers you can afford to come in less steep if you're desperate, t34's and tiger, the steeper the better, not because they can kill you any easier, but more because they absolutely need to be attacked on the top.
to OP:
these are my general method of gv attack. as others have said, kill ords, you'll avoid most bomb****s.. if you bring a wirble or ostwind along, most IL2's will stay away also, or some fighters kill the il2's and the bomb****s, then other side brings fighters to kill the fighters that killed the bomb****s, then buffs kill VH's, fighters go after buffs, more il2's come in, etc. etc. before ya know it, a good ole AH battle which we all know and love.
