Karnak, unless the Meteor pilots were under threat from the buzz bombs, like if they had proxy fuzes and would blow up if a meteor got too close, or something, then thats not quite combat. IMO, combat implys that the other side is shooting at you, or at least in your general direction. The buzz bombs were being launched off at cities, not at the meteors. Really, unless you would say destruction of any enemy ordnance, be it bombs, rockets, or even bullets, before it reaches the target is combat, regardless of the circumstances, even if the one who fired the bullet is miles away and not shooting at you, then shooting down buzz bombs isn't combat.
They weren't being shot at the Meteors, the Meteors weren't really under threat of destruction besides from pilot error or mechanical failure, therefore shooting buzz bombs isn't true combat.
The ground-attack missions, and Fi-156 i'll give you.
