In the raw you fire flak at the aim point - which the flak has to be able to see.
What happens if the aim point is out of los due to a hill etc, BUT the air support template still covers the AA unit? How can it then be argued that the AA can't fire at the aircraft that is bombing it?
I think that we might be binning the los to the target point bit- not sure it's bares scrutiny anyway when planes tend too be some way above the terrain!
Have others come up against this?
