There are lots of texts on how to fight other aircraft, attack bombers, dive-bomb/torpedo ships, but I haven't been able to find any good info on how to tackle mobile AAA. I have yet to even encounter a single personal account in WW2 of someone attacking mobile AAA.
The lethal range of most AAA is beyond the lethal range of most aircraft guns, and the introduction of the Ostwind with its considerable armor makes it a salamanderly kill.
Strafing AAA requires heading right at it, which gives it a zero degree deflection shot. Not good odds. With net lag, a guy can peg you before you even realize you're inside his lethal range (I do better against airfield AAA than mobile AAA).
Korean and Vietnam-era personal accounts indicate the use of 500lb dumb bombs(HE/frag) and napalm (oooh, the latter would be good against open-topped Ostwinds
) But dropping dumb bombs accurately outside the Ostwind's lethal range is difficult. Rockets I thought would be a good standoff weapon, but they seem to go inert outside 1k range.
Gangbanging seems to help, assuming you can see his tracers, but it requires bravery beyond what I've seen lately
Desert Storm style "tank plinking" with medium bombers works okay too, but it's difficult to get one on station high enough to avoid getting hit.
Any tips?
