IMO, its interference unless an airfield is under direct threat. If someone bombs your hangers, then thats an invitation to bomb HANGERS, its not an invitation to bomb TANKS. I always respond in kind. If our attack bogs down because of bomb tards, then I go grab a few squadies and kill twice as many of their tanks.
I bomb flacks and campers impartially and can't complain when I get bombed under those situations.
And Rich, it has just been balanced out. There is no real reason that the Il-2 should have F3 view. Come to that, neither is there any reason that the A20, Boston, Mossie 16, Ju-87, D3A, B5N, or the SBD to have F3 view. Its just representing the multiple gun possitions alearting the rest of the bomber crew if a fighter is seen.
