Certainly happened (my bold, above) to me: first minute the Flakvierling arrives, I hear a droning aircraft sound, then ... kaboom ... one kaput flak unit, without firing a shot. Makes the non-AA capability seem even more ironic when a purpose designed flak unit cannot even disrupt the aim of the air strike!
I know that we always want everything, right now, but - given the level of abstraction which seems to be already present in air strikes - would it have been soooo hard to add an AA layer to the calculation? (Or enhance it for the specific new AA assets, if one is already present to represent the general level of ground fire at the attacking air asset - sometimes from BOTH sides in real life!) Presumably the air attack resolution already checks for e.g. does the requested strike arrive at all?; weather / visibility?; does it see a target?; does it hit the target? How difficult is it to add another layer to the calculation that asks e.g.: is an opposition specific AA asset present?; is it not currently targeting a ground target / not suppressed?; how many gun tubes/calibre/Rof?; what terrain is it sited in (for view of aircraft)?; then add a combined AA defense factor to the airstrike outcome calculation? There are no complex actual sighting and round tracking calculations to do, as the aircraft is never actually physically "present" in the same way that ground units are, is it? And it would not need actually to shoot down the attacking aircraft (relatively rare, but possible), but just be another factor that disrupts its aim and persistence?
If this seems like too much of a moan, let me say thanks specifically for this scenario, and for GL generally - great!
